Add NuGet package version to ThisAssembly

I’m working on a .NET tool which will add a reference to a NuGet package to a project file, very similar to what nbgv does.

For this, I’d like to use a property on ThisAssembly which would return the NuGet package version.

@AArnott what do you think?

If there was a NuGetPackageVersion available in ThisAssembly, it would be easy to compare.

Really? What compare method would you use? You’d need to know whether the version string is using semver1 or 2 rules then use a compare function appropriate for that semver syntax. It wouldn’t be a simple Version class comparer. Would you redist a NuGet assembly and use its comparer function?

I’ve been trying to use the AdditionalThisAssemblyFields

That would have very specific build ordering requirements. But it should be possible. Like this:

<Target Name="AddNuGetPackageVersionToThisAssembly"
        DependsOnTargets="GetBuildVersion"
        BeforeTargets="GenerateAssemblyVersionInfo">
  <ItemGroup>
    <AdditionalThisAssemblyFields Include="NuGetPackageVersion" String="$(NuGetPackageVersion)" />
  </ItemGroup>
</Target>

correct, using Nuget.Versioning to provide SemVer-compatible version comparison, to enable auto-update for the application itself, and (future plan) application content, aside using Nuget Core/Protocolto handle feed, download and unpacking. All worked well from the ground for public releases, just got stuck when offering an additional update channel for “developer versions” which are basically non-public releases in nbgv semantic (and served of a separate feed). Certainly not a standard use case.

aweseome just did a quick test and seems to do that I needed, saves me from string-mangeling metadata into release labels for non-public releases. Thanks for quick response, and great tool!
