I'm trying to make a great GUI for my csgo cheat. I decided to use C++/CLR. Firstly I create empty project then, I change in a properties entrypoint and the subsystem and I add this code to the cpp file:

#include "MyForm.h"

using namespace System;`

using namespace System::Windows::Forms;`

[STAThreadAttribute]
void Main(array<System::String ^> ^args)
{
 Application::EnableVisualStyles();
 Application::SetCompatibleTextRenderingDefault(false);
 SmallPackofCheats::MyForm mainForm;
 Application::Run(%mainForm);
}

Then I save it and I restart visual studio. I run visual studio and I design menu. Designer works. After ended work I save everything and I close Visual Studio. Every next run of the Visual Studio and after opening my project I have this problem: image link

How to solve this problem? Thanks in advance.

This VS feature is not actively being maintained anymore since the C++ Winforms templates were removed in VS2012. Stuff keeps falling off with each release. This particular issue is not a huge problem, rebuilding the project was always enough in my experience. More about this in this post. – Hans Passant
Thank you very much you've solved my problem every thing works after cleaning and rebulding project. – user8233624

I encountered a similar problem recently and the other suggested solutions did not help. This method, however, did work:

  1. Window -> Close all Documents (or at least ensure that every designer window is closed)
  2. Close VS and restart it (important!)
  3. Reopen the solution
  4. Build -> Rebuild Solution

Now you should be able to open the designer.
