How to generate Personal Access Token

Error Message: VSSDK: error VsixPub0029 : An error occurred while communicating with the marketplace: VSIXValidatorWarning08 - (CsharpMacros) An open ended version range was detected in an InstallationTarget element in the .vsixmanifest file.

Solution: Make sure that PackageManifest/Installation/InstallationTarget@Version is a range with both ends defined explicitly. Example of correct manifest:

<PackageManifest Version="2.0.0" xmlns="http://schemas.microsoft.com/developer/vsx-schema/2011" xmlns:d="http://schemas.microsoft.com/developer/vsx-schema-design/2011">
  <Installation>
    <InstallationTarget Id="Microsoft.VisualStudio.Community" Version="[15.0, 17.0)" />
  </Installation>
</PackageManifest>

Error Message: Response status code does not indicate success: 403 (The specified API key is invalid, has expired, or does not have permission to access the specified package.).

Solution:

1. Make sure that you set Acquire and Manage permission in the section Marketplace of your Personal Access Token configuration.
2. Sometimes you need also set Organization to the All accessible organization.
