VS.NET 2005 ASP.NET Component

[Michael Lang]

I have a class deriving from System.ComponentModel.Component.

In VS 2003 I could drag it on to a web form. However I'm finding in VS 2005
whilst it functions perfectly at runtime. At design time in VS.NET 2005 you
can not drag the component on to a web form. When I select customize
toolbox and select my dll containing the component I can see the component
listed and checked. After clicking OK the component is not actually
available in the toolbox. Selecting show all, displays the component
however it is disabled (greyed out) and cannot be dragged on to a web form.

This same component works in VS.NET 2005 as it did in 2003 for Winforms
projects, but not Webforms.

It seems VS.NET 2005 has decided that my component is not applicable to
ASP.NET.

I've attempted adding the System.Web.UI.ToolboxData attribute however it
made no difference.

Can anyone explain how VS.NET 2005 decides what is and what isn't an ASP.NET
component?

If you want code to replicate it...
Just create an empty class derived from component.

Well that was a surpirising lack of response for an issue that after some
research turns out has been quite well known for quite some time. It seems
this was widely discussed during the beta period...

Basically the functionality my code relied on has been taken away and is now
unavailable in VS 2005. It seems like you can no longer have components
that work at design time with both windows forms and asp.net.

Both the lack of response here and the changes that have been made seem
extremely odd to me.
