After compiling the code and running its output through Ildasm.exe, the resulting IL text file can be hand-edited to add the missing attributes. and makes an executable.

IL Spy already has this feature so I guess this shouldnt be too difficult to implement this in VS too. I would add that explicit statements from the copyright owner about usage and decompilation is incredibly important. It allows you to navigate directly to the decompiled source using F12, however this will only lead you back to where you are stuck now. Based on my tests it does not do this currently. Also I would welcome if there was an option to generate not only C# code, but also IL together with C#. This could be a killer feature.
