C#

var newForm=(Form)Activator.CreateInstance(null, "aFrmInCurrntCntxt").Unwrap();

newForm.Text = "some new form";

newForm.Show();

In this two-string-parameter variant of Activator.CreateInstance, if the first parameter string, "AssemblyName," is 'null:' MS says: "the executing assembly is searched."

Note this flavour of CreateInstance returns a "System.Runtime.Remoting.ObjectHandle" that must be unwrapped.

This technique does not require Reflection.

Tested and verified in a simple WinForms app.

Hope this helps.

Why not use FindTypes[^] directly?
