runtime: Asserts not working in WinForms .net Core apps

• .NET Core Version: 3.1.6.

• Have you experienced this same bug with .NET Framework?: No.

Problem description:

System.Diagnostics.Trace.Assert and System.Diagnostics.Debug.Assert are not working in WInForms .net core apps. Programs are silently crash.

Expected behavior: No crash, and assertion dialog must appear after assert.

Minimal repro: Create new WinForm core project. Put System.Diagnostics.Debug.Assert(false, "test"); anywhere in the code, for example:

protected override void OnShown(EventArgs e)
{
    base.OnShown(e);
    System.Diagnostics.Debug.Assert(false, "test");
}

run project (Debug conf.) with ctrl+f5. P.s. if run with f5 - no crash, but and no assertion dilaog (only message in output).
