Am I missing something?  I can't seem to find the web control library template in visual studio 2008.

C# -> Windows -> WPF User Control Library

Visual Basic -> Windows -> WPF User Control Library

I don't think that's what I am looking for.  That is a windows project template. 

File | New | Project | Visual C# | Web -> ASP.NET Server Control. You can add more controls into the same project.

Thanks.

Thanks, I was looking for this also. Following these steps the first thing I noticed is that there is no presentation (ASPX)  file to go along with the control.

I have created a few web controls in various projects. For obvious reasons I would like to add them to a user control library so that we benefit from re-usability. How do I achieve these things?

 
 Thanks!

ASPX file does not make sense in a class library. Class library is client-side project (even with Web controls) so it is unable to run a Web server to display aspx page (aspx cannot be opened directly in a browser). You need to add a Web site project to the solution and add class library as a reference to the Web site.

Did you create custom controls or user controls (ascx)? With custom controls you should only have class libraries, you may want to merge several into one. You cannot build library of user controls, user controls are not indended to be distributed in an assembly (compiled form).
