Describe the bug

When the TargetFramework is missing, the issue is reported as part of the infrastructure, in files the user may have never heard of before, and that they can't fix.

To Reproduce

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

  <PropertyGroup>
    <!--<TargetFramework>net10.0</TargetFramework>-->
    <ImplicitUsings>enable</ImplicitUsings>
    <Nullable>enable</Nullable>
    <IsPackable>false</IsPackable>
  </PropertyGroup>

On any console app or test project.

Exceptions (if any)

Severity Code Description Project File Line Column Suppression State

If not, then the TargetFrameworkIdentifier and/or TargetFrameworkVersion properties must be specified explicitly. TollTests C:\Program Files\dotnet\sdk\10.0.300\Sdks\Microsoft.NET.Sdk\targets\Microsoft.NET.TargetFrameworkInference.targets 109 5

Further details

I made this mistake as I was working with directory.build.props and mistaken about what was in the props file. I realize it looks like a pretty dumb mistake, but this is the kind of thing that makes people think MSBuild is scary :witch:
