Microsoft.VisualStudio.Sdk meta package and Microsoft.VisualStudio.TemplateWizardInterface reference have build conflicts about vsextensibility HOT 2 CLOSED

It is expected that there are incompatibilities between mismatched versions of TemplateWizardInterface and the metapackage. Could you please let us know which versions of the packages you were using? For example. I got errors just as you described with this:

<PackageReference Include="Microsoft.VisualStudio.SDK" Version="16.0.206" ExcludeAssets="runtime">
    <IncludeAssets>compile; build; native; contentfiles; analyzers; buildtransitive</IncludeAssets>
  </PackageReference>
  <PackageReference Include="Microsoft.VisualStudio.TemplateWizardInterface">
    <Version>17.0.0-previews-1-31314-256</Version>
  </PackageReference>

But this worked fine:

    <PackageReference Include="Microsoft.VisualStudio.SDK" Version="17.0.0-previews-1-31314-256" ExcludeAssets="runtime">
      <IncludeAssets>compile; build; native; contentfiles; analyzers; buildtransitive</IncludeAssets>
    </PackageReference>
    <PackageReference Include="Microsoft.VisualStudio.TemplateWizardInterface">
      <Version>17.0.0-previews-1-31314-256</Version>
    </PackageReference>

It is unfortunate that the default new Vsix project behavior leads you to the first option (we're working on that).

I forgot to mention the problem is when you use Microsoft.VisualStudio.TemplateWizardInterface and Microsoft.VisualStudio.Interop as regular references to the local Visual Studio installation folder. But I was not aware that there is a Microsoft.VisualStudio.TemplateWizardInterface NuGet package. So, everything is fine from my perspective.

Thank you!
