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?
The generated classes are partial. If you create a new class in your project with the same namespace and class declaration you can add the [ExcludeFromCodeCoverage] attribute to your partial class. That way you don't have to go back and edit the Reference.cs file whenever you refresh your reference.
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.
System.Diagnostics.CodeAnalysis.ExcludeFromCodeCoverage can be used on top of the class. This is a poor option since you need to redo this anytime you regenerate your code. Maybe Microsoft could do this for us automagically when creating service references, entity framework types, etc...
You could create a code generator that emits partial classes with the DebuggerNonUserCode attribute.
