IsTrimmable and EnableTrimAnalyzer are not supported for the target framework. Consider multi-targeting to a supported framework to enable trimming, and set IsTrimmable only for the supported frameworks. For example:

<IsTrimmable Condition="$([MSBuild]::IsTargetFrameworkCompatible('$(TargetFramework)', 'net6.0'))">true</IsTrimmable>

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.

Because this call is not awaited, execution of the current method continues before the call is completed. Consider applying the 'await' operator to the result of the call.

Nullability of reference types in type of parameter 'sender' of 'void Program.TaskScheduler_UnobservedTaskException(object sender, UnobservedTaskExceptionEventArgs e)' doesn't match the target delegate 'EventHandler<UnobservedTaskExceptionEventArgs>' (possibly because of nullability attributes).

Non-nullable field 'Check' must contain a non-null value when exiting constructor. Consider adding the 'required' modifier or declaring the field as nullable.
