NuGet packages downloaded directly are unusable

When a NuGet package is downloaded from Nexus, it has the name "mypackage-1.0.0.nupkg".

If you use the the directory the nuget package is downloaded in as a source for a nuget install, it is unable to find the package due to the name.

If you edit the downloaded file name to be "mypackage.1.0.0.nupkg" (which is the same as what the package name is when a nuget install is done and the source is a Nexus repository) then it will be found by NuGet and installed.

The package name should be updated when downloading from Nexus, to have a "." instead of a "-" before the version number so that the package is usable by NuGet.
