sandboxed web parts inside SharePoint 2010

Is it possible to develop a web-par开发者_运维百科t in ASP.NET (framework > 2.0), to have a sandbox architecture, and deploy those web parts inside Share Point 2010 and/or MOSS 2007

we donot want to use any SharePoint dll reference with web parts we develop.

we refer to the url, section at http://msdn.microsoft.com/en-us/library/ee539417.aspx (section Web Parts in Sandboxed Solutions)

i referred the following How Tos, hope it helps some one ..

I've just hit this problem - looks like it's not meant to be possible which is really annoying.

See: http://msdn.microsoft.com/en-us/library/gg615454.aspx

Specifically:

Application pages, mobile pages, and user controls (.ascx files) cannot be deployed in a sandboxed solution.

However, there is a workaround (hackaround!) here:

I'd love to have a better way!
