Using a System.Windows.Forms.WebBrowser inside ASP web form

I am converting a windows application which contains a web browser control
into an ASP.net application.

The Windows project references all manner of html controls in the WebBrowser
control and retrieves values using the HtmlControlCollection class etc.

I was hoping I was going to be able to work with the
Windows.Forms.WebBrowser object from inside my ASP.net webform by simply
adding a reference to System.Windows.Forms and doing code like below:

WebBrowser webBrowser = new WebBrowser();
webBrowser.DocumentText = "<html><body>my document</body></html>;
HtmlDocument htmlDocument = webBrowser.Document;

However, it blows up with the following error:
ActiveX control '8856f961-340a-11d0-a96b-00c04fd705a2' cannot be
instantiated because the current thread is not in a single-threaded
apartment.

Is there any way to get round this problem. It would save having to totally
rewrite this project.

Many thank,

CodeRazor
