I am unable to install a package (using package restore) due to some kind of versioning issue with Nuget. Here are the steps I took:

build project: error : The schema version of 'MagicalUnicorn.MvcErrorToolkit' is incompatible with version 1.6.21205.9031 of NuGet. Please upgrade NuGet to the latest version from http://go.microsoft.com/fwlink/?LinkId=213942.

Extension manager says version is: 2.0.30619.9119.

Ok, restart VS as administrator, extension manager uninstall nuget. restart VS as administrator again, search for nuget and install.

Extension manager again says version is: 2.0.30619.9119.

rebuild project: error : The schema version of 'MagicalUnicorn.MvcErrorToolkit' is incompatible with version 1.6.21205.9031 of NuGet. Please upgrade NuGet to the latest version from http://go.microsoft.com/fwlink/?LinkId=213942.

Ok, so restart VS as administrator, extension manager uninstall nuget again. This time download from http://visualstudiogallery.msdn.microsoft.com/27077b70-9dad-4c64-adcf-c7cf6bc9970c Run the installer, all seems ok.

Extension manager again says version is: 2.0.30619.9119.

rebuild project: error : The schema version of 'MagicalUnicorn.MvcErrorToolkit' is incompatible with version 1.6.21205.9031 of NuGet. Please upgrade NuGet to the latest version from http://go.microsoft.com/fwlink/?LinkId=213942.

Grr! Any ideas?

I was facing the same issue. I resolved it by selecting Tools on VS 2010 Menu --> Library Package Manager --> Package Manager Settings --> Check "Automatically check for updates". After that I restarted VS and was prompted for Nuget Update Installation. Once the update was installed, the Nuget package, HTTP Client in my case, got installed smoothly.
