I didn’t want to add the NuGet packages of my Visual Studio solution to TFS, because I download all NuGet packages during build.

To exclude all NuGet packages from TFS:

• Add a folder “.nuget” to the folder that also contains the “packages” folder and in most cases the “solution file”.
• add a file to the “.nuget” folder with the name “NuGet.config”
• contents of the file:

<?xml version="1.0" encoding="utf-8"?>
<configuration>
  <solution>
    <add key="disableSourceControlIntegration" value="true" />
  </solution>
</configuration>

• Add a file “.tfignore”  to the folder that also contains the “packages” folder and in most cases the “solution file”.
• contents of the file:
• \packages
