SignIn issue

[Banchio]

Followed all the steps to create app registration, permissions, bot service etc etc but when I add this in code:

[Message] public async Task OnEveryMessage(IContext<MessageActivity> context, [Context] IContext.Client client) { if (!context.IsSignedIn) { await client.SignIn(); } }
I obtain a Stack Overflow exception with a VERY long stack trace :), a snippet is reported at the end of the issue, should be enough to get the recursion problem.

If instead of client.SignIn() I use await context.SignIn(); I obtain this exception:
System.InvalidCastException: 'Unable to cast object of type 'Microsoft.Teams.Apps.Context1[Microsoft.Teams.Api.Activities.MessageActivity]' to type 'Microsoft.Teams.Apps.IContext1[Microsoft.Teams.Api.Activities.IActivity]'.'

Examples lacks on documenting this for C#, actually in the dotnet docs there are typescript snippets.
Thanks!

going deep on this, I am missing something on the configuration part because I found that I receive a signin/failure activity which causes the infinite recursion (and stack overflow). Please see image below, class is SignInActivity.cs

In the error I see this "value":{"code":"resourcematchfailed","message":"Resource match failed"} but I do not understand which resource it refers to.

Hope this can help someone until is resolved.
Using Fiddler and DevTunnel inspect I analyzed the network traffic. Ended up in:

• add https://token.botframework.com/api/oauth/signin to the url in the app registration. I do not recall to have seen this in the doc but this is what is sent by the signinrequest endpoint in the bot framework
• I needed to modify the tokenExchange request to the botframework endpoint because of a 400 error. Specifically the body of the request must be {"token": "tokentoexchange"}. In the current implementation there is an useless object called exchangeRequest wrapping the token exchange request coming from UserTokenClient.cs

Hey thanks for opening this issue. I will look into this shortly.

P.S. We're going to be updating the C# docs very soon to be up to date.
