How to ignore generated code from code coverage data

Question

I am using Visual Studio 2010 and would like to exclude the generated service reference code from my code coverage statistics.

I found an article pre 2010 that mentions using DebuggerNonUserCode and DebuggerHidden attributes. I have tried this an it works as advertised. DebuggerNonUserCode is set at the class level, but with 50+ classes generated in each of the generated service reference code files, this is not an attractive option.

Does anyone have any alternative solutions?

Answer 1

You could create a code generator that emits partial classes with the DebuggerNonUserCode attribute.

Answer 2

In Reference.cs, you can find an existing attribute, like "[System.Diagnostics.DebuggerStepThroughAttribute()]" and do a search and replace with "[System.Diagnostics.DebuggerStepThroughAttribute()] [System.Diagnostics.DebuggerNonUserCode()]". The major drawback is that you have to redo this each time you update the reference.

I don't understand why MS does not make the code coverage tool smart enough to skip service reference generated code.
