Any ideas. Thanks.

Answer 1

I had the same issue and was able to resolve it by commenting out the Microsoft.ApplicationInsights.Web.AspNetDiagnosticTelemetryModule in the ApplicationInsights.config.

Answer 2

I started getting this message in the past two months or so and now i think i found the problem.

As you can see in this issue on Github it seems there's a problem when using ApplicationInsights v2.4.0 because it references a dll called System.Diagnostics.DiagnosticsSource (v4.4.0) and (as stated in the issue) this new reference causes the problem.

The date that they were copied to that folder was about two months ago (when this issue started to happen for me). And i coudn't reproduce this problem in DEV/QAS because the dll's were not "installed" in these environments.

When i removed these dll's from the bin folder of my app the problem was gone. Since my app didn't reference these dll's for nothing there was no problem removing them.

But if you can't remove them, it seems v4.5.0 of System.Diagnostics.DiagnosticsSource will fix this problem but it was not officially released yet. Keep track of the Github issue for more details.

Answer 3

Here's how I fixed mine.

1. Find the NuGet package System.Diagnostics.DiagnosticSource installed in your web project. Mine was already at the latest version.
2. Downgrade it to the last stable version. In my case, it was 4.4.0.
3. Once downgrade is complete, upgrade it again to the latest version. Rebuild solution and check. My error went away.

The down/up grading process updated the items needed in web.config to make it work again.

Answer 4

Just been through the pain of this message! We are using webroles on azure with RDLC's being part of key things such as invoice print.

For us the answer was to go to the properties of the webrole and TURN OFF "enable diagnostics".

ATM, this is still with MSFT support so cannot give you a reason why, but this fixed our issue of RDLC's crunching live ! Hope this helps someone Regards Peter
