I am trying to follow this tutorial for Azure AD authentication in a .NET core web app:
https://github.com/Azure-Samples/active-directory-aspnetcore-webapp-openidconnect-v2/tree/aspnetcore2-2
and I get this error:
The type or namespace name 'OpenIdConnectOptions' could not be found (are you missing a using directive or an assembly reference?)
I am using Linux and have no issue getting the basic templates to generate and build, the issue appears to arise where the tutorial says to add this line:
services.Configure<OpenIdConnectOptions>(AzureADDefaults.OpenIdScheme, options =>
{
options.Authority = options.Authority + "/v2.0/";
options.TokenValidationParameters.ValidateIssuer = false;
});
I have tried adding packages (semi randomly) e.g.:
Microsoft.IdentityModel.Protocols.OpenIdConnect
Microsoft.Owin.Security.OpenIdConnect
to no avail as the error persists and I get new issues like:
Error: Package 'Microsoft.Owin 4.0.0' was restored using '.NETFramework,Version=v4.6.1' instead of the project target framework '.NETCoreApp,Version=v2.1'. This package may not be fully compatible with your project.
I am not sure if I am missing some basics with authentication and running .net core on linux, I am new to this and just trying to get the ball rolling with a working demo that actually does something :)
I have not checked on linux yet, but the nuget package you are missing should be produced by ASP.NET Core from the following project: https://github.com/aspnet/AADIntegration. Did you try to update the latest nuget package of ASP.NET Core ?
As a workaround you might want to have a look at the following branch of the sample (which still has the code which was now moved to ASP.NET Core AADIntegration) : https://github.com/Azure-Samples/active-directory-aspnetcore-webapp-openidconnect-v2/tree/master
ran into the same issue. After installing these modules, it compiled.

I am working on a web project with .Net core 3.1.
I need to use FormsAuthentication.SetAuthCookie in login action and when i add using System.Web.Security to project its unknown. I cant add this using.
I read all posts about but still wasn't able to solve this.
I studied many references and finally the result was nothing else this :
System.Web.Security only is available with .net framework and in core has no alternative or i couldn't find it.
I'm trying to limit the amount of data sent to Application Insights in a .NET Core program. I'm attempting to follow the documention here which says I should use the UseAdaptiveSampling method. It has the rather cryptic instruction:
Use extension methods of TelemetryProcessorChainBuilder as shown below to customize sampling behavior.
However, it doesn't tell me where exactly this extension method lives. My code is as follows:
public AppInsightsStats(string appInsightsKey)
{
TelemetryConfiguration configuration = TelemetryConfiguration.CreateDefault();
configuration.InstrumentationKey = appInsightsKey;
telemetry = new TelemetryClient(configuration);
// Enable sampling since amount of logging is massive
var builder = configuration.DefaultTelemetrySink.TelemetryProcessorChainBuilder;
builder.UseAdaptiveSampling(maxTelemetryItemsPerSecond:5); // <-- Compiler error here
}
However, the code doesn't compile since UseAdaptiveSampling isn't found. I have the following using statements:
using Microsoft.ApplicationInsights;
using Microsoft.ApplicationInsights.DataContracts;
using Microsoft.ApplicationInsights.Extensibility;
The source code I can dig up that uses UseAdaptiveSampling all seems to be .NET Framework 4.5 code, so I'm wondering if this just isn't included with the .NET Core version. These instructions are for ASP.NET Core, but I'm wondering if they mean running that on the .NET Framework on Windows.
For console project, you should use this package Microsoft.ApplicationInsights.WorkerService. It's used for non-http application like console project.
I used your code with this package, everything is ok. Please give it a try, and let me know if you still have the issue.
I'm trying to upload a blob to azure using a shared access signature. I have the token and added the nuget package WindowsAzure.Storage to my project. I've tried both version 7.0.0 and 7.0.1-preview.
For some reason I'm unable to resolve the reference when creating an instance of CloudBlobContainer. Also I've tried to just type the using statement but no luck. All azure documentation points to a version 4.4.0-preview, is this the one I should be using?
azure doc ref https://azure.microsoft.com/da-dk/documentation/articles/storage-xamarin-blob-storage/
Best regards
I would just guess that the docs are outdated with the 4.4.0-preview link instead of a link to the NuGet package:
https://www.nuget.org/packages/WindowsAzure.Storage/
CloudBlobContainer seems to be within the Microsoft.WindowsAzure.Storage.Blob namespace.
I would check to ensure that you actually installed the NuGet package as it may have failed silently with other projects.
EX: http://screencast.com/t/FLhztkeu
Changing the PCL profile worked for me. Bizarre.
After installing the NuGet package, you actually need to change the profile on your Xamarin project. You can do this by going to the shared project -> Options -> General – > C#
Change the Current Profile to PCL 4.5 – Profile111 (I have no idea
of what this does.)
You need to retarget your NuGet packages for this new profile now.
Right click on Packages within the shared project, and you’ll have 5
options here.
Retarget will be available. Click that. (Not shown here, as I’ve
already retargeted)
Rebuild your project
How I figured this out
I stumbled across this Xamarin forum post, where someone had the exact same issue. One user pointed us towards a bug report, where PCL references were not added automatically via NuGet package installation. They recommended retargeting, and it worked! Now I can include the using Microsoft.WindowsAzure.Storage.Blob; namespace.
I have a blog post with more info on this.
I'm trying to read a message from an Azure ServiceBus queue using an Azure WebJob but it's throwing and exception:
Unhandled Exception: System.InvalidOperationException: Found 2 DNS claims in authorization context.
I've set the correct connection strings named "AzureWebJobsServiceBus", "AzureWebJobsDashboard" and "AzureWebJobsStorage"
The WebJob Program code has been updated to use JobHostConfiguration:
class Program
{
static void Main()
{
var config = new JobHostConfiguration();
config.UseServiceBus();
var host = new JobHost(config);
host.RunAndBlock();
}
}
And the actual Job method
public class Functions
{
public async static Task ServiceBusResizeRequest(
[ServiceBusTrigger("blah")] string message,
TextWriter log
)
{
await log.WriteLineAsync("got message " + message);
}
}
I can successfully create and write to the queue via a separate console application.
But when I run the webjob application, it throws that exception.
Any ideas?
EDIT: Using .net 4.6.1
The answer marked as solution, is not the solution, it is a botched job.
The solution to use it in .Net Framework 4.6.1 is to add in the rutime block in App.config:
<AppContextSwitchOverrides value="Switch.System.IdentityModel.DisableMultipleDNSEntriesInSANCertificate=true" />
Read this article Mitigation: X509CertificiateClaimSet.FindClaims Method
Very IMPORTANT for now Azure WebApps / WebJob etc, doesn't support 4.6.1 I will note here when (said at jan 21, 2016).
It means, that you can develop a web job application with 4.6.1, but when you push it to Azure, you can see exceptions like Job failed due to exit code -2146232576
January 29th Microsoft released version 3.1.3 of the NuGet package WindowsAzure.ServiceBus.
From the release notes:
• General: .Net 4.6.1+ compatibility fix. Fixing custom DNS IdentityVerifier so that we honor multiple DNS claims returned by WIF
Upgrading the package solved the problem for us.
As outlined in this answer above, the snippet below does the trick
<runtime>
...
<AppContextSwitchOverrides value="Switch.System.DisableMultipleDNSEntriesInSANCertificate=true" />
...
<runtime>
BUT be carefull to add it to the correct project in your solution! Add it to the project containing the Azure code and Azure references.
Microsoft released a new package (under a new name) to fix this issue. So ...
remove the Microsoft.AspNet.SignalR.ServiceBus package,
install the Microsoft.AspNet.SignalR.ServiceBus3 package instead, and
upgrade the WindowsAzure.ServiceBus package.
More info here: https://github.com/SignalR/SignalR/issues/3548#issuecomment-296326048
Downgrading from .net 4.6.1 to 4.6 seems to prevent the issue from occurring.
Today, I ran into this issue and had no idea about it. Finally, I decided to upgrade all the Azure nuget packages that I am using (including webjobs, servicebus ...) and BOOM! it WORKS. Hopefully, it will help if anyone runs into this issue in the future
For me it started failing after I updated .NET Framework from 4.5.2 to 4.7
All I did to fix it was update the Nuget Package WindowsAzure.ServiceBus to 5.2.0
I read the previous posts - Tried a few things.
Here is the issue
A simple console OWIN self host app - Not much in there
public void Configuration(IAppBuilder appBuilder)
does not compile.
1. If I say using Microsoft.Owin and using Owin, then I get an error the using directive for owin already appeared. I can't figure out why.
2. If I do using Microsoft.Owin but modify the use as Owin.IAppBuilder
then the compiler says it can't find owin.IAppBuilder.
Yes I tried reinstalling Microsoft.Owin
and Owin (3 times)
I checked the project reference 4.5.1
Here is an issue to consider.
If your using statements are insider a namespace declaration
And your name space starts with Microsoft (for whatever reasons)
Then using Owin ==> looks at Microsoft.Owin
The solution is to use using global::Owin;
