Also look for dependencies in the `bin` folder

As pointed out by #156 (comment) .

This will fix an issue here dependencies are automatically discovered in a .NET Framework console app (where the .exe and its dependencies typically live in the same folder) but not in .NET Framework ASP.NET apps (where dependencies are copied to the bin folder)

This should get easier to implement once the refactorings in #151 are merged
