I recently installed NuGet for Visual Studio 2010 Professional.
I was also able to install same external packages. Since yesterday I am not able to get an overview of available packages any more.
In the Dialog appear the error message: Value cannot be null. Parameter name: frameworkName.
I also tried to uninstall and reinstall nuget version without any change. If I try to get the list of available packages over the powershell command console, it works withou problem.
I have nuget Version 1.6.21215.9133 on a Windows 7 64bit system.
I search the internet for similar problems, but found only one entry in the issue tracker regarding the version 1.5 of nuget.
Help would be very nice
