You can only upload template VSIX files for the Visual Studio Express SKUs.

Question

I am attempting to upload a VSIX file as a Template and I'm getting the above error even though my VSIX only contains a project template. I've included my vsixmanifest and the vstemplatefile.

Answer 1

Ok, found the error. Somehow my vsixmanifest lost it's <Content /> elements children. Once I changed it to:

  <Content>
    <ProjectTemplate>ProjectTemplates</ProjectTemplate>
  </Content>

I can upload my VSIX Project Templates targeting all VS 2010 editions.
