Question

I wasn’t able to set my new form as a startup form, it complained about it not existing.
But after some minutes I tried with typing “Namespace.NewForm” and that worked.

In my other project, The startup is set as this:

        Application.Run(new MyForm());

Why did I have to specify namespace when changing startup form in this project?

Answer 1

Use a using directive so you do not have to fully qualify the types within the namespace in question.

using MyNameSpace;

It’s also worth pointing out that using directives in C# do not give you access to namespaces nested in the namespace you specify (just in case you are wondering). This means that

using System;

does not give you access to System.IO
