We are hosting our site on windows azure where site is running on multiple instances.Due to multiple instances we were using shared cache for storing session values. As Microsoft is going to stop shared cache and recommended to use redis cache to store session. I modified project to use redis cache and it worked for most of the pages. My problem is that, we have a very important page "search page" (we are using lucene.net for search functionality) in our site which stores a lot of data in session and this page is not working. After hitting search button, it shows connecting status in address bar for a long time and goes to oops page of website. We are recording error messages in DB so after looking at there we found following error message.
System.Runtime.Serialization.SerializationException: Type 'myWeb.clsSearchCriteria+ContentCriteria' in Assembly 'HelmBriscoeWeb, Version=1.0.0.0, Culture=neutral, PublicKeyToken=null' is not marked as serializable.

I am not sure if this is related to my problem but seems if this is fixed, page will work properly. Has anyone any idea why this error occurred and how can I fix it?
Thanks
I solved this problem myself by adding serialization attribute to class like below.
<Serializable()> _
Public Class clsSearchCriteria
Thanks

Our installer app uses the following code to verify service account permissions:
try
{
using (svcIdentity.Impersonate())
{
using (SqlConnection conn = new SqlConnection(builder.ConnectionString)) // <<<
{
conn.Open();
...
Omitted for brevity:
The svcIdentity WindowsIdentity is obtained by using the Win32 LSA LogonUser function in advapi32.dll and LOGON32_LOGON_SERVICE.
builder is a SqlConnectionStringBuilder that builds a connectionstring to a local SQL Server database.
Targeting .Net Framework 4.6.
The app runs elevated (requestedExecutionLevel level='requireAdministrator' in the app.manifest).
This code ran flawless until Windows 10 version 1803 (April 2018 update). Since then, the SqlConnection constructor (marked <<<) throws an exception:
The type initializer for 'System.Data.SqlClient.SqlConnection' threw an exception.
The inner exception provides more insight:
Catastrophic failure (Exception from HRESULT: 0x8000FFFF (E_UNEXPECTED))

The stack trace indicates the SqlConnection constructor fails to open a configuration section. Our app.config does not have a connectionstrings section and machine.config and security.config on the tested computers haven't changed since 2017.
The code works when:
Commenting out using (svcIdentity.Impersonate),
or
when setting a breakpoint on the line immediately above the SqlConnection constructor ({) and stepping through the code (???),
or
when adding our application to the registry key mentioned at the end of KB945701
That KB article about a fix for Internet Explorer 9 seems unrelated, except that GetLocationEvidence on the first line of the stack trace seems to take a SecurityZone into account, which applications listed in the corresponding registry key seem to ignore.
Now my question:
Can anybody help me understand what exactly is going wrong, and if there is a better way to fix this than with an obscure registry key? It seems a 'coincidence' that this registry change works and I'm afraid our code might break again if we don't understand exactly why it fails.
Thx.
Hello I have a silverlight project for WP8.1 that is a game. I use a backgroundTask to alert the user about when he last played, if he is too slow to comply I would like to make a call to the server from the bagroundTask to resign from the games.
The backgroundTask is made using stackoverflow and this blog, just basic implementations of the backgroundTask.
I then install the NuGet Package Microsoft.Azure.Mobile.Client and everything is fine, I then do a compile, everything succeeds.
The app installs and splashscreen appears, then I get an error in the main project at the initialization of MobileServiceClient in App.xaml.cs
public MobileServiceClient MobileService = new MobileServiceClient(
"https://xxxxx.azurewebsites.net"
);
The exception in the above line states:
An exception of type 'System.IO.FileNotFoundException' occurred in mscorlib.ni.dll but was not handled in user code
Additional information: Could not load file or assembly 'System.Runtime.InteropServices, Version=4.0.10.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a' or one of its dependencies. The system cannot find the file specified.
The only change was the install of the NuGet package in the backgroundTask project. The stack trace output for the exception above.

I am able to do normal http calls to the web by using the proposed code, replicated here:
BackgroundTaskDeferral _deferral;
public async void Run(IBackgroundTaskInstance taskInstance)
{
_deferral = taskInstance.GetDeferral();
// your async code
_deferral.Complete();
}
Update based on Adrian Halls Answer
The code works, my front application can communicate with the server and everything. The backgroundTask, can extract information from the device everything is fine, everything compiles and runs.
I then add the NuGet package to the backgroundTask and suddenly the above error appears, when I deploy this solution to the client.
I am running VS2015, Win10, and have v2.0.1 installed of Microsoft.Azure.Mobile.Client. I have seen some odd behaviours with silverlight projects on win10 before.
The error indicates a problem with your .NET setup - the error is in mscorlib (the basic library for .NET). Try to add a reference to the specific library that you need. Also, ensure that you have installed v2.0.1 (or later) or the Microsoft.Azure.Mobile.Client library.
I'm working on a WindowsPhone 8.1 app, and I have a SQL database connected to a Web API server hosted on an Azure website. Recently, the database person updated the database, added a new table, and added sample data to the tables that didn't already have any. When managing the database through Azure, I can see that all the tables have data in them, but when I try to retrieve them with the /api/entityname url, it returns an error message.
A few things to note, the database the server connects to has changed since I originally published it. I tried to run the enable migrations and update database commands again, but I don't know how to select the new database it's now connected to. Do I need to republish the server? Run the migrations commands for the new database? I'm hesitant try things involving the database connection on my own since I don't know much about it and don't want to mess up any configurations. I have a .NET backend. Thanks in advance for the help.
Update:
I went into the Web.Config file of my Services project and changed catalog value in the connection string to the name of my new database. Now I get the following error when I try to get the games values using the /api/teams extention:
An error has occurred.The
'ObjectContent1' type failed to serialize the response body for

I think I'm making some progress, but I'm not very experienced with connecting apps to databases, so I'm hesitant to poke around. Thanks in advance for the help. I am using data-first migration (EF Designer from database). Also, the above error message is only displayed when I run the service locally via localhost. When I run it through it's hosted azurewebsites url, I get the following:
An error has occurred.
I assume this is due to my database updates not being published to the hosted site, correct? I'm using Firefox as my browser. If I use IE, I can't download or open the JSON file for the new entities.
With the help of a friend, I managed to fix this problem. In case anyone comes across this post down the line, the problem was due to conflicting data types between the database and the server's data objects. A list of data type mappings between C# and SQL Server can be found at https://msdn.microsoft.com/en-us/library/cc716729%28v=vs.110%29.aspx. Match the data types according to the linked chart, and ensure that any other database constraints (ie: required, etc) are included in annotations. Also, make sure that you update any code in your server's context file to match the data type changes. For instance, I had the following code in my OnModelCreating method:
modelBuilder.Entity<Game>()
.Property(e => e.GameTime)
.IsFixedLength();
Once I changed GameTime to a DateTime property,.IsFixedLength(); no longer applied to it, so I had to comment it out. As you make these changes, you can test them out by debugging your server locally, but you'll have to publish it back to the url it's hosted on in order see the changes take place on your remote server. In my case, I had to republish my azurewebsites.net site. I hope this helps anyone down the line that has a similar issue.
I am using Thinktecture Identity server and running it in azure. The issue I am having is that sometimes when I read the Federation metadata XML file or while signing in I get this Keyset does not exists CryptoGraphic exception . Now i know these exceptions can be caused if we do not have proper permissions but the thing is that it just happens sometimes and other times it is working fine. I am not sure how to debug this. Can someone please lead me in some direction.
Also if someone has any idea about what kind of certificate is this system assembly trying to read and how it is configured that will be very helpful as well.

I developed a simple VB .NET Web API project using .NET 4.5
This project was working perfectly fine, but I decided to install the AttributeRouting nuget package. After installing this package every function seems to raise the following exception:
The constraint entry 'inboundHttpMethod' on the route with route
template 'Company' must have a string value or be of a type which
implements 'IHttpRouteConstraint'.
In this message 'Company' is the route name to a simple GET method that simple returns one object. Every route results in this error message. The stacktrace is:
[InvalidOperationException: The constraint entry 'inboundHttpMethod'

I found the following thread which describes my problem: https://github.com/mccalltd/AttributeRouting/issues/191
Unfortunately, this fix does not seem to help: https://github.com/mccalltd/AttributeRouting/issues/191#issuecomment-13814025
Any ideas on how to fix this?
In your case, I definitely feel like this issue is related with in memory hosting and do have a solution in the link that you mention above.
After updating to MVC 5 I came across this issue and following the workout in this link which ultimately helped me out.
Here is how I did it.
In global.ascx page, I have the following:
AttributeRoutingHttpConfig.RegisterRoutes(GlobalConfiguration.Configuration.Routes);
In AttributeRoutingHttpConfig class, I replaced the code
routes.MapHttpAttributeRoutes();
with
routes.MapHttpAttributeRoutes(cfg =>
{
cfg.InMemory = true;
cfg.AutoGenerateRouteNames = true;
cfg.AddRoutesFromAssemblyOf<Your_API_Controller>();
});
You can overwrite Your_API_Controller with any of your ApiController class. (Yes, don't know why but any api controller you want works ;) )
Hope this helps,
