Try doing a full rebuild, or delete the build files and then build the file. Visual Studio doesn’t always pick up changes to resources, and it can be a pain to get it recompile.

Yes, .NET Framework 4.8 will be the last version of .NET Framework, but since we now have WinForms and WPF continuously developed on top of .NET Core, we should not worry.

You can use the x:FieldModifier attribute on your controls, thusly: <TextBox x:Name=”textBox1″ x:FieldModifier=”private” /> Interestingly the MSDN page for x:FieldModifier doesn’t give “private” as a valid value for the attribute, but I’ve tested it and it works.
