Example of the CS7038 Failed To Emit Module Error with VS 2015

Example of "Failed to Emit Module Example"

Example repository showing the "CS7038: Failed to Emit Module" build error - Roslyn Issue 4196.

The issue occurs when calling a method with default parameters in a referenced assembly that was Obfuscated using Red Gate Smart Assembly 6.8 (and possibly lower), and building using the Roslyn compiler built into the Visual Studio 2015 RTM.

Obfuscating the assembly using Red Gate Smart Assembly 6.9 fixes the build error.

Example Setup

This example is a minimal solution to show the error.

The FailedToEmitModuleExample.Obfuscated project has been obfuscated with both Smart Assembly 6.8.0.121 and 6.9.0.114 (in the obfuscated folder).

The master branch references the assembly obfuscated with version 6.8, this will fail to build in Visual Studio 2015 RTM (but will build in VS 2015 RC or earlier VS versions).

The smart-assembly-6.9 branch references the assembly obfuscated with version 6.9 which builds correctly.
