One of our end users is getting this error when trying to install our package (PrecogClient):
PM> Install-Package PrecogClient
Install-Package : 'Default' tag requires a nonempty 'Extension' attribute. Line 1, position 556.
At line:1 char:1
+ Install-Package PrecogClient
+ CategoryInfo : NotSpecified: (:) [Install-Package], XmlException
+ FullyQualifiedErrorId : NuGetCmdletUnhandledException,NuGet.PowerShell.Commands.InstallPackageCommand
I've tried it from the command line locally and it installs fine, although I'm running this under mono:
» mono --runtime=v4.0 /home/software/dotnet/NuGet.exe install PrecogClient
Successfully installed 'PrecogClient 1.0.0'.
Not sure what the differences are between NuGet.exe and the Package Manager are, but it's unhappy.
