Invalid login token. Issuer doesn't match providerName about aws-cognito-dot-net-desktop-app HOT 4 CLOSED

Looks like the issue is the .NET framework I was using.
Supported version is 4.5

from aws-cognito-dot-net-desktop-app.

What is the error message?

from aws-cognito-dot-net-desktop-app.

Similarly to user rvyasedh, the application gets stuck when trying to access credentials object. The issue occurs in a web application. ASP.NET (4.6.1 framework).

The uploaded code works fine. Noticed a small issue there but not relevant for this problem (if the role associated to the identity pool does not have permissions to access S3, the application reports the username / password could not be validated, although it is an access issue, not an authentication issue).

When executed in a web application, in debug mode, the application seems to hang when it reaches the credentials.GetCredentials().AccessKey instruction.
The application I have does exactly the same thing as this desktop application, only that it is a web application.
When I run in debug mode, I enter the username and password then F11 to step into the application. All works well until I get to the line bucketlist.Append("Access Key - " + credentials.GetCredentials().AccessKey);
When the execution reaches there, the control is given to the web application as if it waits an input from the web page (so I cannot proceed to the next line in the code).

Any help, much appreciated.
