I have this problem when open project with a gradient component (ProgressBar in this moment) and I have an error in the designer window.
Message could not be processed 32 code line in the designer. For more detailed information, see the task list. The code within the method ' InitializeComponent ' is generated by the designer and should not be edited manually. Remove any changes and try to reopen the designer.
This is the error reported:
32 Me.PrgTry.BackGradientStartColor = System.Drawing.Color.FromArgb(CType(CType(209, Byte), Integer), CType(CType(211, Byte), Integer), CType(CType(212, Byte), Integer))
Software: Visual Studio 2015 Professional and :NET FrameWork 4.5 (but I have this error with .NET 4.6)
