I must admit I haven't tested my solution with .NET 4.0 / VS2010 yet and considering the age of this post, I might do well in rechecking the proposed solutions. Your control being a grandchild shouldn't be an issue though. What version of Visual Studio and/or .NET do you use?

It is nested to the 3 level (a grandchild). Oh, I forgot to mention, it is a nested user control that is causing the problem. It is nested to the 3 level (a grandchild).

Can I not debug my application with your code, or am I doing something wrong with my build configuration/process? If I put the data from the ExecutionMode properties in a message box I get exactly the same values in designer as I do running the application - though UserMode is never true, however, I gather it will be when it is published. Tony Hi Abel,

Whenever I run the code from Visual Studio (F5 or Ctrl+F5) my application still thinks it is in DesignMode using your code. Can I not debug my application with your code, or am I doing something wrong with my build configuration/process?

If I put the data from the ExecutionMode properties in a message box I get exactly the same values in designer as I do running the application – though UserMode is never true, however, I gather it will be when it is published.

This article is about a .NET control in a .NET environment. .NET, but its nature, has no knowing of the COM environment. To find out whether you're in design mode you need to call the correct COM interface method on the host. Unfortunately, I have yet to see an example of how to retrieve that method. Luckily, there's another way.

I've been trying to get designview or usermode to work in any form and this gave me hopes, but when run from VB6 in the designer and from executable no assemblies work. In fact all methods provide the same results. Possibly I'm not exposing a particular attribute but I'm at a loss. It works perfect when embedded in .net apps. or a current release of visual studio. This is the most intelligent writeup on this, so I thought I'd ping you. I have a C# UserControl that exposes Com for Interop purposes in a VB6 Application.

Dynamic loading is exactly what is done when loaded in a designer. You could say, that with my approach, I consider all dynamic loading siting in a designer. If you need to support dynamic loading, you may want to be careful with this approach. I currently have no idea how you can support that without resorting to existing worse methods.

Won't the "Recursive EntryAssembly Reference Lookup Test" fail in such case? Hi,
