Is this a bug on Visual Studio or AxWMPLib::AxWindowsMediaPlayer?

Microsoft Visual Studio Community 2019 Version 16.8.4.

This is a CLR Project (.NET Framework 4.5).

I'm not sure about the origin of this bug, so I cannot fill in a bug report to its respective program.

I either found a bug on Visual Studio Community 2019 or AxWMPLib::AxWindowsMediaPlayer. When adding a custom control derived from AxWMPLib::AxWindowsMediaPlayer in the Designer, if you switch the Language of the form by the Designer then it gets all blank and you are forced to close the Designer. For another custom controls like derived from System::Windows::Forms::* that bug doesn't happen.

This is my ClassLibrary1.dll e.g:

#pragma once

using namespace System;

namespace ClassLibrary1 {
    [System::ComponentModel::ToolboxItem(true)]
    public ref class MyMediaPlayer : public AxWMPLib::AxWindowsMediaPlayer
    {
    public:
        MyMediaPlayer() {}
    };
}
Solution

  • Problem solved on version 16.8.6. So it was actually a Visual Studio bug.
