Hi @abdul rahman alif putra ,Welcome to Microsoft Q&A,
When I add the AForge namespace in the nuget center, I can add the target control you mentioned correctly.
It is recommended that you clean the project or recreate it to add it.
In addition to dragging and dropping directly, you can also add directly using code.
For example:
AForge.Controls.VideoSourcePlayer player=new AForge.Controls.VideoSourcePlayer();
this.Controls.Add(player);;
Best Regards,
