That doesn't seems to be the issue. I checked and all the packages are ok.
The problems I get are related to VS SDK. For example, on the Zippy.Chirp project, I'm missing the Microsoft.VisualStudio.Shell reference. I don't have any "Shell" only item in my assemblies. I only have the ones that ends with "Interop"
(from 7 to 10).
I found the Microsoft.VisualStudio.Shell.dll on the VS folder, under the "PrivateAssemblies" folder. I'm able to build chirpy (had to change the target platform to .net 4.5 because this new dll was built against that), but on the post build,
ILMerge throws an error because that assembly now it seems to be private: "An exception occurred during merging: Unresolved assembly reference not allowed: Microsoft.VisualStudio.Shell."
Not sure how to continue...
