Thanks to the PowerShell template for VS.2005 wiping out all my standard templates I had to uninstall (pretty long) and reinstall the whole thing again. My setup is: Microsoft Windows Vista Business Visual Studio 2005 SP1 Ajax Extensions So I installed products in this order (SQL Server is already installed): 1) VS.2005 PRO 2) WWF Extensions: Visual Studio 2005 Extensions for Windows Workflow Foundation (EN) 2) VS.2005 SP1 VISTA: VS80sp1-KB932232-X86-ENU 3) Ajax Extensions 1.0 for .NET 2.0: (ASPAJAXExtSetup After quite a long time (hours) I tried to open my web applications project (created prior to the template wipe out) and VS tells me still that the project is not supported/recognized. When I try to create a new web application project there is no "ASP.NET Web Application" template in the New Project dialog either. I am down to my 2nd re-install cycle, any ideas?
