Code coverage, analysis and profiling for dynamically generated code

Question

I have a demo project, which creates an assembly and uses it. I also can debug the injected code. But if I run coverage, analysis or profiling, it is counted, but I want to measure it.

Code:

CSharpCodeProvider codeProvider = new CSharpCodeProvider();
ICodeCompiler icc = codeProvider.CreateCompiler();
CompilerParameters parameters = new CompilerParameters();
parameters.GenerateExecutable = false;
parameters.GenerateInMemory = false; // debug enabled                
parameters.OutputAssembly = "DynamicCode.dll"; // if specified creates the DLL
parameters.IncludeDebugInformation = true;
CompilerResults results = icc.CompileAssemblyFromFile(parameters, "InjectedCode.cs.txt");

I create the DLL to check the generated IL code. I can debug the code in VS. But when I run coverage, the generated assembly is simply missed, if I use TEMP directory, or if I output the DLL (like above) NO FILE is included in the coverage (so not even the main assembly).

When I run profiling, I can only see the invoke (reflection), but nothing about the generated code. When I do analysis (I have some errors in the injected code, e.g not used locals, and ofc analysis for everything), no problems are reported from the injected code. The injected code:

namespace CodeInjection
{
    public static class DynConcatenateString
    {
        public static string Concatenate(string s1, string s2){
           //  System.Diagnostics.Debugger.Break(); // break here for debugger and also test comment output
            int a = 1+2+3+4+5; // complicated math
            int b = a+2;
            int c = 0;

            return s1 + " !"+b+"! " + s2;
        }
    }
}

I would like to use coverage, profiling and analysis on the generated code (mainly coverage).

Ok code coverage in VS 2012 does not have full support for dynamically generated code.

You can run our analyze command to see that your module has been skipped for this very same reason or is it because of a missing symbol/p
