Got this error today while trying to install MSBuildTasks for a DNN Module development project and used NuGet:
install-Package : Method invocation failed because [NuGetConsole.Host.PowerShell.Implementation.PSTypeWrapper]
doesn’t contain a method named ‘AddFromFile’.”

I copied this error message to Google and found no match. After some digging, with portion of error words, found some tips linking to the fact that NuGet might need a face-lift. So I went back to VS2010 project, uninstalled the NuGet and re-installed it. Then run PM>install-package MSBuildTasks again, it went through with not error.

Hopefully this tip will be picked up next time someone would run into the same error message I got here.

Cheers!
