I've come across this error using Visual Studio Development Server when my project output directory was not bin\

One of my DLLs has versions for different platforms (x86, x64), so I created corresponding configurations, and they got by default output directories like this:

bin\x86\Debug 
bin\x64\Debug

But the Visual Studio Development Server still tried to load binaries from the bin\ folder and of course failed.

I fixed the issue by specifying bin\ output folder in my debug configurations.
