Embedding Winform control in asp.net page

Hi, has anyone managed to successfully embed a Winform control in a browser/asp.net page using .Net v4.0.  I have had this working for years in a .Net v1.1 app using the <object> element.  I am now trying to upgrade to .Net v4.0 but I can't get the winform control to display.  I appreciate that I should really be upgrading  the control to something like silverlight but there is a lot of code/functionality and as an interim solution I just want to host the winform control in the asp.net page as I did before.

To get it working in v1.1 I had to assign full trust to the local intranet zone (the web app is running in an intranet) using the .Net configuration wizard.  To test that my problem was a security issue I could disable code access security using 'caspol -s off' command.  Neither of these exist in .Net v4 so I am a bit stumped.

Any help would be appreciated.

Thanks

I am not sure how you reply helps me.  The linked article seems to be about ClientIDs on WebForms.  My issue relates to embedding WinForms in a web page.

ok, after a lot more research it appears that this functionality is no longer supported in .Net Framework v4.  The best explanation I have found is in the following forum post:

It seems that if you need to be able to embed a winform in a browser then the latest .net version you can use is v3.5.

I now have this working in .Net v3.5 which confirms the problem was v4 not allowing it.
