Release Candidate

The following are the changes made in this Release Candidate since CTP 2. Visit the Issue Tracker to see the full list of bugs.


The following are the most significant changes made in CTP 2:

  • Switched the package feed from ATOM to an OData service endpoint: If you upgrade to the CTP2 version of NuGet, be sure to add the following URL as a package source:
  • Renamed the Add-Package command to Install-Package.
  • Updated the .nuspec Format. The .nuspec format now includes the iconUrl field for specifying a 32x32 png icon which will show up in the Add Package Dialog. So be sure to set that to distinguish your package. The .nuspec format also includes the new projectUrl field which you can use to point to a web page that provides more information about your package.

This build will not work with old .nupkg files. If you get null reference exceptions, you're using an old .nupkg file and need to rebuild it with the updated NuGet command line tool.
