This is a follow-up to another question.
I have a migrated .NET framework project which I'm trying to package using msbuild -t:pack and the corresponding NuGet.Build.Tasks.Pack.
I have included all of my NuGet information in the *.csproj-file, like so:
    <TargetFramework>net48</TargetFramework> <!-- Error! -->
    <PackageId>Testcenter.RobotFramework</PackageId>
    <Version>1.0.0</Version>
    <Authors>Testcenter Team, Some person</Authors>
    <Company>Some company</Company>
    <PackageOutputPath>$(ProjectDir)</PackageOutputPath>
    <Description>A class library to implement a remote library interface conforming to RobotFramework.</Description>
    <Title>RobotFramework Remote-Library-Interface for C#</Title>
    <Copyright>Copyright (c) Some company 2022</Copyright>
    <RepositoryUrl>https://redacted-url.com/repos/testcenter.robotframework/browse</RepositoryUrl>
    <Product>Testcenter.RobotFramework</Product>
    <AssemblyVersion>1.0.0</AssemblyVersion>
    <FileVersion>1.0.0</FileVersion>
Due to an error I am unable to use the TargetFramework property, normally used in SDK-style projects.
How do I add that property or anything for that matter, so that NuGet recognizes that I target net48 and shows that information in the packaged project?
I was not able to find information about this in the target frameworks documentation, because it only speaks of SDK-style projects, and apparently I cannot use their attributes in the project. Also, I did not find a similar documentation meant for Non-SDK projects.
