Hello

I have an ASP.NET MVC 5 application and I have added Application Insights to it. I simply did it in Visual Studio in the meny "Configure Application Insights...". It works and I can see data in Application Insights. I see all requests, both 200 and failing ones.

But, I cannot see the Exception part. If I click on a 500 request, there is no information on what went wrong, and I cannot see the Exception information or the Stack Trace.

What can I do to be see the Exception and the Stack Trace in Application Insights.

Thanks!

    Hi @Julia ,
    If you have no data for Application Insights, I'm guessing that the problems are these:

    1. It's probably a firewall issue.
    2. IIS Server might be missing some prerequisites, like .NET Extensibility 4.5 or ASP.NET 4.5.

    More details,you could refer to below article:
