How to generate the access Token to access the Proxy Application using AcquireTokenSilent method.

Question

How to generate the access Token to access the Proxy Application using AcquireTokenSilent method.

I have used the AcquireTokenSilent method but the method returns null result.

Below is the code snippet

**var scopes = new string[] { todoListResourceId + "/user_impersonation" };

        AuthenticationResult authResult;

        //authResult = await clientApp.AcquireTokenSilent(scopes, account).ExecuteAsync();

        try

        {

            authResult = await clientApp.AcquireTokenSilent(scopes, account).ExecuteAsync();

            //authResult = await 

        }

        catch (MsalUiRequiredException ex)

        {

            authResult = await clientApp.AcquireTokenInteractive(scopes).ExecuteAsync();

        }**

Here in** authResult ** i am getting null result.

Thanks :)

AcquireTokenSilent() is used to get the cached token tied to the users login identity. If expire and a refresh token is available, it will the refresh token to get the access token.

this all requires the user has successfully authenticated and the token was stored. Also if a server farm, a distributed cache is required.

show your configuration code for the initial authentication.
