I just posted .NET Micro Framework Unit Test Sample Project on Codeshare. Feel free to discuss and make suggestions here.
@ 4egod - Good job! Will this work in VS Express?
Yes, VS Express is supported by vsix package, but I didn’t test this possibility. I checked the package in VS Ultimate 2013 and 2012.
Package also support NETMF 4.1, 4.2, 4.3, but required to reinstall of the NuGet package:
Update-Package -reinstall MFUnitTest
