The type initializer for '<Module>' threw an exception

Question

I had one source code having 25 projects in single solution. It is consisting of both c++ as well as C# project. But now i wanted to call one of C# project(which is of windows application type) calls from a separate test project. I created a separate c# project and added the source reference, and created a object of source code class. it is building fine. but at the time of execution, it is throwing:

The type initializer for '<Module>' threw an exception

Please give me suggestion to resolve this issue.

Answer 1

I got this execption and when I looked at the stack trace, it had another exeception: Arthimetic operation resulted in overflow. In my case, the application I was trying to run, required 32-bit mode where as the IIS in my Windows 8 machine runs in 64-bit mode by default. I had to set Enable 32-bit Applications to true for the AppPool this application was using.

Experienced a similar problem when catching the error with a try-catch... Upon removing the try-catch block the full trace indicated FIPS as the culprit. Toggling the registry switch to 0 for FIPS solved the problem in this case.
