Empty TargetFramework breaks the build

[hankovich]

I have the following content in my csproj

<PropertyGroup>
  <TargetFramework /> <!-- used to override the default value specified in Directory.Build.props -->
  <TargetFrameworks>netstandard2.0;net8.0</TargetFrameworks>
</PropertyGroup>

And the build is broken

10>------ Build started: Project: Extensions, Configuration: Debug Any CPU ------
10>C:\.nuget\packages\nugetizer\1.0.5\buildMultiTargeting\NuGetizer.targets(14,3): error MSB4020: The value "" of the "Project" attribute in element <Import> is invalid.
10>Done building project "Extensions.csproj" -- FAILED.

If I'll remove <TargetFramework /> then everything will work as expected. As being said, it's needed to override the default value that comes from Directory.Build.props.

BTW calling nugetize from the command line shows another error NuGetizer.targets(14,3): error MSB4020: ╨╖╨╜╨░╤З╨╡╨╜╨╕╨╡ "" ╨░╤В╤А╨╕╨▒╤Г╤В╨░ "Project" ╨▓ ╤Н╨╗╨╡╨╝╨╡╨╜╤В╨╡ <Import> ╨╜╨╡╨┤╨╛╨┐╤Г╤Б╤В╨╕╨╝╨╛., so it looks like errors in russian are not displayed correctly.

I can't repro this. The library:

<Project Sdk="Microsoft.NET.Sdk">

  <PropertyGroup>
    <PackageId>ClassLibrary</PackageId>
    <PackOnBuild>true</PackOnBuild>

    <TargetFramework />
    <TargetFrameworks>netstandard2.0;net8.0</TargetFrameworks>
  </PropertyGroup>

  <ItemGroup>
    <PackageReference Include="NuGetizer" Version="1.1.0" />
  </ItemGroup>

</Project>

The clearing of TF seems to breaking other things in VS, even if I remove nugetizer:

Ensure that restore has run and that you have included 'net8.0' in the TargetFrameworks for your project.

From cmdline it works though.

Perhaps this was a fluke in the editor?

Also, the russian error message is not from nugetizer but MSBuild itself (messages with codes starting with MSB are built-in ones).

Closing for now since I couldn't repro. Please reopen if you can provide a reliable (and ideally isolated) repro.

Thanks!
