I need to invoke office communicator to create a chat window and phone call directly from Silverlight when running out of browser. When running in browser I do this and it works pretty well:
System.Windows.Browser.HtmlPage.Window.Eval(String.Format("window.open(\"sip:{0}\", target=\"_self\");", sip));
When running out of browser as far as I have gotten is to invoke the Communicator.UIAutomation via a dynamic but honestly I don't know what to do next.
dynamic communicator = AutomationFactory.CreateObject("Communicator.UIAutomation");
Anyone have any suggestions on how to make this work? Searching has yeilded zero results.
A couple thoughts:
Have you tried making the automated Communicator object a var, then setting a breakpoint and digging into the resulting hydrated object? You might find some methods or properties on the object you can use to make things happen.
There's a blog here that describes the Office Communicator SDK and has some sample projects. I think you might be able to include the SDK assemblies in your OOB app and automate Communicator using Microsoft's provided SDK.
The SDK has to be preinstalled in the user machines. There's no easy way to deploy it along your Silvelright OOB application.
You will need the SDK.
You can check the documentation for more details here: C:\Program Files (x86)\Microsoft Office Communicator\SDK\OCSDK.chm
It mainly refers to C#, but most of it could easily be ported to Com Automation. As an example look at the following code to start a conversation
dynamic comm = new ActiveXObject("Communicator.UIAutomation");
dynamic msgrAdv = comm.IMessengerAdvanced;
if(msgrAdv!=null)
{
try
{
object obj = msgrAdv.StartConversation(
1, //CONVERSATION_TYPE.CONVERSATION_TYPE_IM,
sipUris, // object array of signin names
null,
"Testing",
"1",
null);
windowHandle = long.Parse(obj.ToString());
}
catch (COMException ex)
{
this.writeToTextBox(
formReturnErrors.returnComError(ex.ErrorCode)
);
}
I hope this help. Noticed that from the example in the help file I changed some of the members that are defined in the .NET Assembly (which can't be referenced from your C# code). If you need this, I would suggest opening the CommunicatorAPI.dll assembly in Reflector.

We use the Microsoft.SharePoint.Client library to automate SharePoint work from our workflow engine but yesterday, one of our client informed us they wanted to disable the Legacy Authentication (LegacyAuthProtocolsEnabled to false).
Once I tried it on our end, I ended up getting an Unauthorised exception.
All in good wanting to disable the Legacy Authentication for obvious security reason, but the problem with the Modern Authentication is that it requires user interaction which is clearly not a solution since we are running tasks in the background.
I've been googling this for quite some time but I haven't found a solution as of yet on how to handle automatic authentication for background work.
Is there a way to "authenticate" to SharePoint without any user interaction while LegacyAuthProtocolsEnabled is set to false?
I found an article that suggested using the App Authentication but after reading more about it, I believe this is considered an old method to authenticate and is likely to be deprecated as well over time, but I thought I'd still give it a go just in case but it did not work. When I got to
https://tenant.sharepoint.com/_layouts/15/appregnew.aspx
Where tenant is our company domain name, and I click on the "Create" button after filling in all the relevant fields, I get the following error, which is completely useless:
Sorry, something went wrong
An unexpected error has occurred.
TECHNICAL DETAILS
According to this article HOW TO HARDEN YOUR SHAREPOINT ONLINE ENVIRONMENT BY DISABLING LEGACY AUTHENTICATION, Legacy Authentication was no longer be an option as of the 13/10/2020, yet here we are, and the option is still available in SharePoint 365 and while the article is interesting explain why Legacy Authentication should be switched off, etc... it does not get into any details as to how automated solutions should be handled.
Also found an old thread "LegacyAuthProtocolsEnabled" and Scripted Logons to SharePoint Online? where #DeanWang suggests leaving it turned on as:
All custom CSOM, PowerShell code will stop working
This may also prevent third-party apps from accessing SharePoint
Online resources.
I'm going to stop here as I could keep going and the question is already too long for my liking and bottom line is, does anyone know if there is a way, and what is the best way, to authenticate to SharePoint while running automated "scripts/code" from a background task without requiring any user interaction while the Legacy Authentication is switch off?
Thanks
Update-1
After reading articles after articles, I've yet to connect to SharePoint 365.
I also spend more time on the PnP Framework as recommended by numerous articles. I created a dummy app with the following sample code which is used again in various articles, including this one:
Secure Authentication of SharePoint with PnP Framework with C#(Code)
My code is identical as you can see:
var clientContext = new AuthenticationManager().GetACSAppOnlyContext(
"https://mycompany.sharepoint.com/sites",
"MyClientid",
"MySecretId");
using (clientContext)
{
//Get Lists
var web = clientContext.Web;
var lists = web.Lists;
clientContext.Load(lists);
clientContext.ExecuteQuery();
foreach (var list in lists)
{
}
}
And even though I've granted full control in Azure for the specific test app that's using the specific ClientId and SecretId
I'm still getting the following error (401 - unauthorized):

Is there another section I should be looking at (and change) in the App Registration in Azure
Since it's the SharePoint Online that we are talking about, one easy way to connect to different SharePoint Sites is by using the Azure AD App-Only approach and since you are talking about a Deamon Service you can easily use Application Permissions when registering the App Registration.
You can, and you should, read more about it from the linked Microsoft Docs article.
You can also loggin via certificate or app registration secret as it is discribed in the Log in to Microsoft 365 in order to create automated CI CD SPFx pipelines, for example.
Hope the above helps, if not feel free to ask :)
Update: Please read below in order to have a better understanding.
Firstly, in your code segment you are using a wrong method from the PnP.Framework package.
AuthenticationManager().GetACSAppOnlyContext()
The above method refers to a completely different method of obtaining an authentication token, more specifically the Sharepoint App-Only model, which... well.... more or less is not being used nowadays quite so ofte. I think I read somewhere that MS is thinking of retiring this kind of Authentication and going onwards on the path of Azure Active Directory authentication, but, unfotunately, I cannot seem to find the link.
Furthermore, I have collected three projects and uploaded them to github for you to see. You can simply clone the repo and run the projects as-is from HERE.
As you will be able to see for yourself, there are three projects in the solution, which you can run each one individually from VSCode or Vs.
More in detail:
ConsoleApp1
(sorry for the name but forgot to switch it :) )
This is a Deamon Console Project that references the PnP.Framework namespace and tries to utilize all of the goodies that the good folks form the PnP Community have contributed.
The procedure is straight forward and is the same for all three projects ->
Read the AppConfiguration
Request the Access Token with appropriate scopes (Depending the service that i am referencing)
Declare the Token to be used by our Client Context.
In the PnP.Framework-related project the above cycle can be seen as below
AuthenticationConfiguration config = AuthenticationConfiguration.ReadFromJsonFile("appsettings.json");
var authManager = new PnP.Framework.AuthenticationManager(config.ClientId, config.Certificate.CertificateDiskPath, config.Certificate.CertificatePassword, config.Tenant);
using (var cc = authManager.GetAccessTokenContext("https://<REPLACE:name of tenant>.sharepoint.com/sites/testsite2", (string siteURL) => authManager.GetAccessToken(siteURL)))
ConsoleAppMSGraph
As the name suggests this Deamon Console App utilizes GraphServiceClient graphClient in order to get all the information that you request through the graph endpoint.
Subsequntly, you will notice that for this porject the scope name changes to
string[] scopes = new string[] { "https://graph.microsoft.com/.default" };
In addition, we request a collection of all the lists that currently reside in our SharePoint Root Site with the below segment:
var lists = await graphClient.Sites["root"].Lists
.Request()
.GetAsync();
ConsoleAppSPClient
This app is the default and most simple way of accessing data on Sharepoint.
The projects utilizes MSAL.Net and Microsoft.Sharepoint.Client namespaces in order to fetch an access token and, subsequently, embed that token in all our next requests.
In order to keep the answer a bit short, please refer to here in order to see how we initiate a Confidential App Client, request for a token and, later on, embedd it in our ClientContext object.
Notes
I have listed in the Readme.md of the repo, which permissions you should give to your app registration. You can view them Here.
I am using the Sites.FullControl.All but you can narrow down the list of sites that the app registration will have access by using the Sites.Selected.
All of the above projects, reference a common class library that serves as a strongly typed configuration object.
IMPORTANT you should always use a certificate to authenticate the client app as it is mentioned here. The previous link also describes the way you can create a certificate and upload it to the store of the app registration.
Amazing! Thank you very much #Jimas13. For the last 2 weeks I was struggling to find solution to my problem!! You saved me!! If you ever been in Greece let me buy you a drink!
I have a simple custom Add-in that just displays a message to the user.
namespace GeorgiSpotfireCustomExtention
{
public class GeorgiEvent : CustomApplicationEventHandler
{
protected override void OnApplicationInstanceCreated(AnalysisApplication application)
{
base.OnApplicationInstanceCreated(application);
MessageBox.Show("On Application Instance Created");
}
}
}
That is my CustomAddIn class:
public sealed class CustomAddIn : AddIn
{
// Override methods in this class to register your extensions.
protected override void RegisterApplicationEventHandlers(ApplicationEventHandlerRegistrar registrar)
{
base.RegisterApplicationEventHandlers(registrar);
registrar.Register(new GeorgiEvent());
}
}
I am just trying to learn the package deployment process. When I am running it locally - in the installed Spotfire Analyst client it displays the message just fine:
However, when I package the extention, add it to the server (via the "Deployments & Packages" section, adding the "spk" file and then saving the area, the message is not shown when I try to open a document in the WebPlayer/Consumer.
Notes: I am choosing "TIBCO Spotfire Any Client" for my intended client in the Package Builder when building the spk file.
from the Spotfire Wiki (emphasis mine):
WinForms graphical user interface is a component of the .NET Framework and not something supplied by Tibco Spotfire. It's not recommended to implement solutions using Forms, but sometimes it could be handy when debugging. There is no commitment that it will work in future versions of the Analyst client. Forms are not supported on the Web Player.
the example listed on the wiki is for IronPython, but presumably the same holds true for C# extensions.
Correct. My assumption, and I don’t really know a lot about .NET, so this is not absolute, is that the form is rendered on the machine executing the code. In the case of your example above, the dialog would pop on the Node Manager host. If you’re really set on using an alert like this, you can accomplish it in JavaScript with an ‘alert()’. There is probably a way to render dialogues o in the web client too, but I don’t know it offhand.
I have a WebApp on Azure that uses a dll. This library needs Interop libraries x86 and x64.
Sometimes, at the restart of the App (I suppose), the App fails due to an exception:
System.EntryPointNotFoundException: Unable to find an entry point named 'sqlite3_config' in DLL 'SQLite.Interop.dll'. at System.Data.SQLite.UnsafeNativeMethods.sqlite3_config_none(SQLiteConfigOpsEnum op) at System.Data.SQLite.SQLite3.StaticIsInitialized() at System.Data.SQLite.SQLiteLog.Initialize() at System.Data.SQLite.SQLiteConnection..ctor(String connectionString, Boolean parseViaFramework) at T_Dox.WebService.SQLiteDb.CreateConnection() at WebService.CeDb.Connect()
The SQLite used is the SQLCipher's one.
What am I missing here? I don't understand why the app stops working suddenly even if I don't make any changes.
The App is a Web Service (.asmx file) that uses a data access layer to perform some business logic.
It was under a web site project, then we moved it into another project, a webapi\mvc project.
The routing bypasses this extension, so it works as before, a simple web service call.
The called web method initializes a business class loaded from another .net library (a VB.Net library).
Inside, this class uses a wrapper to a sqlConnection, in this case the SQLiteConnection.
In its constructor it starts an SQLiteConnection, and normally it works.
Then it performs some CRUD operations ...
So I can represent the operation this way:
[WebService(Namespace = "...")]
[WebServiceBinding(ConformsTo = WsiProfiles.BasicProfile1_1)]
public class SampleService : System.Web.Services.WebService
{
[WebMethod]
public ServerInfo Test()
{
var sampleBusinessClass = new SampleBusinessCLass();
sampleBusinessClass.DoSomething();
using(var connection = new SQLiteConnection()) //the constructor is the parameterless one
{
//...
}
}
}
And the stack will be this (this is not the real one):
System.EntryPointNotFoundException: Unable to find an entry point named 'sqlite3_config' in DLL 'SQLite.Interop.dll'.
at System.Data.SQLite.UnsafeNativeMethods.sqlite3_config_none(SQLiteConfigOpsEnum op)
at System.Data.SQLite.SQLite3.StaticIsInitialized()
at System.Data.SQLite.SQLiteLog.Initialize()
at System.Data.SQLite.SQLiteConnection..ctor(String connectionString, Boolean parseViaFramework)
at xxx.WebService.SampleService.Test()
It always works, but sometimes it starts to launch this error until the stop and start of the web application on iss (in our case: Azure).
Inspecting the System.Data.SQlite.dll I can clearly see the entry point and actually it always passes this internal code (no conditions that can bypass this part) and it generally works.
The System.Data.SQlite.dll (1.0.96.0 version) is provided by SqlCypher product. I think it is the original System.Data.SQLite one because at first sight I can see the same assembly manifest and content.
The interop System.Data.SQLite uses is probably modified by SqlCypher team to give their features.
To avoid possible issues we put the interop in the path /bin/x64, then we compile our web app ONLY in x64 and it runs on a x64 environment.
This is regarding SharePoint 2010 Integration with MSCRM 2011.
While creating a record in CRM, trying to create a Custom Document location for that record and a similar folder in sharepoint, So that when user clicks on document link in the entity record it does not prompt user to create folder in Sharpoint (Trying to avoid sharepoint noise for better user experience)
I have implemented through post create asynchronous plug-in. (I did this through console program working fine). Build the plugenter code here-in and deployed to CRM.
When creating a record it error out with a message like "An internal server 500 error - Could not load the assembly with public key token etc…blab bla bla…”
But when I am debugging the plug-in it failed at the first line of command where I am instantiating sharePoint method Create client context of sharepoint, it says [System.Security.SecurityException]={“That assembly does not allow partially trusted callers”.}
As per google, per this issue it should be having one attribute “Allow partial users” in assembly info file. As per my understanding, this should be done in because the request goes from CRM plug-in to SharePoint dll. I mean share point dlls are not allowing request from my assembly. How can we change that?
I have referenced Microsoft.SharePoint.client.dll and Microsoft.SharePoint.Client.Runtime.dll
What is the alternate to overcome this issue?
Appreciate if some one can help me ..Thanks In advance.
Here is my code for SharePoint
ClientContext clientContext = new ClientContext(siteUrl)
CredentialCache cc = new CredentialCache();
Cc.Add(new Uri(siteUrl), "NTLM", CredentialCache.DefaultNetworkCredentials);
clientContext.Credentials = cc;
clientContext.AuthenticationMode = ClientAuthenticationMode.Default;
Web web = clientContext.Web;
SP.List list = web.Lists.GetByTitle(listName);
ListItemCreationInformation newItem = new ListItemCreationInformation();
newItem.UnderlyingObjectType = FileSystemObjectType.Folder;
newItem.FolderUrl = siteUrl + "/" + folderlogicalName;
if (!relativePath.Equals(string.Empty))
newItem.FolderUrl += "/" + relativePath;
newItem.LeafName = newfolderName;
SP.ListItem item = list.AddItem(newItem);
item.Update();
clientContext.ExecuteQuery();
Where I am passing the siteurl, folderlogicalname,relativepath and new foldername as parameters.
This works fine from my Console application. But when converted to CRM plug-in it gives the above specified issue
I've seen a similar issue before.
CRM plugins run inside a sandbox, so all assemblies and .NET libraries used must allow partial trust callers (since the CRM sandbox runs under partial trust). It works in the console because you are executing the code as a full trust user in that context.
This issue is not necessarily your code, but could be a dependency or a .NET library itself does not allow partial trust callers - in your case it sounds like the Sharepoint library is the culprit (but a stack trace of the error should reveal exactly where the cause is).
Since you don't have access to the source library causing the problem, to overcome the error you will likely have to create a wrapper. However, the problem is the wrapper cannot directly reference the problem library or you will get the same issue. So to get around this, you may have to create a web service which acts as your wrapper and then call the web service in your CRM plugin. This way the full trust code is executed by the web service (which is full trust) and then returns the result to your calling CRM plugin.
Here is more info on the error.
Thanks Jason. This works for me.
I Would like to add additional few points to the answer.
1. I have added the sharepoint dlls to the bin folder of CRM 2011 site.
2. Also deployed the same dlls in the folder whereever Async job is running to make my Async plug-in to work.
Thanks once again for the cooperation
I'm writing an application in which I have to log on to a CRM 2011 server from ASP.NET code. I quickly found this article:
http://msdn.microsoft.com/en-us/library/cc156363.aspx
The problem I'm having is in this bit of code from that article:
//Create the Service
CrmService service = new CrmService();
service.Credentials = System.Net.CredentialCache.DefaultCredentials;
service.CrmAuthenticationTokenValue = token;
service.Url = crmurl;
Visual Studio can't resolve CrmService. So I tried to add a web reference to this project and point the web reference at the CRM service I'm using. The URL I'm getting from Settings->Customizations in CRM, and I'm using the Organization Service endpoint. However, after I add that reference CrmService is still unresolvable. What am I doing wrong?
First off, you have linked a CRM 4 MSDN article, some things have changed so you might want try this one instead: Authenticate Users with Microsoft Dynamics CRM Web Services.
Then as an alternative you may want to try the CrmConnection class, its a helper library in Microsoft.Xrm.Client. It means you can use a connection string approach to authenticate with CRM (and let the class takes care of all the hard work).
var connection = CrmConnection.Parse("Url=http://crm.contoso.com/xrmContoso; Domain=CONTOSO; Username=jsmith; Password=passcode;");
var service = new OrganizationService(connection);
var context = new CrmOrganizationServiceContext(connection);
You can also keep the connection strings in config files makes life significantly easier.

If you're using standard AD authentication with a local environment this answer should work fine: How to Authenticate to CRM 2011?
Actually, the login procedure is heavily dependent on the authentication provider you're targeting. I'm currently in the process of structuring that info in a pedagogic way on my blog so you're welcome to check it out and nag if it's too techy.
There are at the moment four such ways.
Active directory
Live id
Federation
Online federation
Which is applicable in your case, you should know already. If not, there's code for that too uploaded just a few days ago.
using Microsoft.Xrm.Sdk;
using Microsoft.Xrm.Sdk.Client;
...
public AuthenticationProviderType GetAuthenticationProviderType(Uri address)
{
IServiceManagement<IOrganizationService> organizationServiceManagement
= ServiceConfigurationFactory.CreateManagement
<IOrganizationService>(address);
return organizationServiceManagement.AuthenticationType;
}
Assuming that you're aiming for AD, you're in luck. It's the easiest.
Uri organizationUrl = new Uri("http ... Organization.svc");
OrganizationServiceProxy organizationService = new OrganizationServiceProxy(
organizationUrl, null, null, null);
If you're aiming for Live Id - that's stingy. I'm still trying to set up a graspable example. The ones at MSDN are just too heavy and confusing. At least when one's dense and lazy like me. More info at mentioned but undisclosed location.
