当我从控制台应用程序打开它时，为什么我的 Windows 窗体布局会发生变化？

Question

At the beginning of my Project I am starting a Console. After the Console executes my code, a new Form gets open. The Problem the Form looks really strange, not like i designed it in the Editor.

Form in the Editor, like i designed:

Form after I opened it from the Console-Project:

Code in the Console-Project for opening the Form

Application.Run(new Form1());

One more thing: I am using .NET Core 3.1

Anyone has a solution to this problem?

thanks in advance!

If you want the same "theme" you should EnableVisualStyles as the first line in your main method. As outlined in the documentation.

Also call SetCompatibleTextRenderingDefault with false as this is also the default since 2005.

The following are the defaults when creating a new winforms project for dotnet core 3.1

Application.SetHighDpiMode(HighDpiMode.SystemAware);
Application.EnableVisualStyles();
Application.SetCompatibleTextRenderingDefault(false);
