With the exception of Microsoft Internet Explorer, .NET controls are not supported in applications designed to host ActiveX controls.
Microsoft .NET 1.0 Windows Forms controls are supported in Windows Forms and Internet Explorer 5.01 and later versions. .NET 1.1 Windows Forms controls are supported in Windows Forms, Microsoft Foundation Classes (MFC) 7.x, and Internet Explorer 5.01 and later versions. Other applications and development tools that are capable of hosting ActiveX controls, including the ActiveX Test Containers from versions of Visual Studio that are earlier than Visual Studio .NET 2003, are not supported hosts for .NET Windows Forms controls.
The supportability information in this article also applies to the use of .NET controls through COM Interop. The use of a .NET control through a COM Callable Wrapper (CCW) is supported only in Internet Explorer. For more information on this please see article 317346 listed below.
