MVVMLight package handling failure

The latest version of MVVMLight package (from the official nuget feed) cannot be server correctly by nuget. The package has indeed some duplication in its nuspec file, but nuget server can serve it or even when serving from a directory.
However, ProGet cannot serve it.

Are you getting an error message? Can you be more specific?

There is a known issue (PG-71) that relates to framework-specific depdency searching (for example... 4.1.27.0:net35 ≤ x), but this does NOT seem to impact MVVMLight in my quick testing.

The error in the VS Extension as follows:

'MvvmLightLibs' already has a dependency defined for 'CommonServiceLocator'

This comes after CommonServiceLocator was successfully installed.

You can reproduce it by downloading the MvvmLight package & its dependencies (MvvmLightLibs & CommonServiceLocator) from NuGet official feed and hosting them in ProGet.

Ah, thanks; it would appear I wasn't on the latest version of NuGet... where this seems to be an issue.

This is related to the aforementioned issue and should get resolved by PG 2.0.
