Custom build with StrongName

[axd2201]

I need to add " [assembly:AllowPartiallyTrustedCallers];" to the Assembly info of some projects of SharpDX, which i managed to do and compile, but they were not strong named, i decompiled them edited the .il file to add the key to the SharpDX as a reference, and failed horribly, somehow i broke the assemblies and they wouldnt work, so here is the big question How can i build locally with AllowPartiallyTrustedCallers with .snk key
OBS: Already tried to add an key in the same folder of the .sln file, it gives compiling error
