Assets file '/home/runner/work/tns2tool/tns2tool/tns2tool/obj/project.assets.json' doesn't have a target for 'net6.0/linux-x64'. Ensure that restore has run and that you have included 'net6.0' in the TargetFrameworks for your project. You may also need to include 'linux-x64' in your project's RuntimeIdentifiers.

Process completed with exit code 1.

The "--output" option isn't supported when building a solution. Specifying a solution-level output path results in all projects copying outputs to the same directory, which can lead to inconsistent builds.

For projects targeting .NET 8.0 and higher, specifying a RuntimeIdentifier will no longer produce a self contained app by default. To continue building self-contained apps, set the SelfContained property to true or use the --self-contained argument.
