A couple of months ago I posted how to add OpenID to your existing web site in conjunction with ASP.NET Membership. In the comments a few times I was asked to post the code to the OpenID login user control or to create a sample project to share. Even though there really isn't a lot to the code other than what I shared in that article I said that I would post the sample code. After ScottGu linked to my original post last week I felt compelled to step up the pace of doing so.
Below is a link to the sample solution/project/web application. There is really nothing to the web site itself, just a static home page, a "join" page and a "login" page that use traditional membership controls and the OpenID login user control. Go ahead and check out the code and feel free to use that control and the accompanying utility code in your own projects. Please read the Readme.txt file included in the zip for setup instructions.
