AbleCommerce Shopping Cart Software

Has anyone been able to get AbleCommerce installed and built/compiled using Visual Studio? I'm using VS2010 and am trying to install a new installation of 7.0.5 and continue running into build errors. I set this up as a web site project and initially get an error about the ScriptManager. I refreshed the AjaxControlToolkit.dll reference (not sure what else to do):

• The name 'ScriptManager' does not exist in the current context. (\App_Code\PageHelper.cs, line 522)

I tried correcting this error by replacing "ScriptManager" with "page.ClientScript" and ended up with more errors (183 total):

• The 'CodeFile' attribute cannot be used without an 'Inherits' attribute. (\Admin\Catalog\AddCategory.aspx) - error appears 78 times for this one page
• The 'CodeFile' attribute cannot be used without an 'Inherits' attribute. (\Admin\Catalog\AddLink.aspx) - error appears 91 times for this one page
• The type or namespace name 'ScriptManager' does not exist in the namespace 'System.Web.UI' (are you missing an assembly reference?) and The type or namespace name 'UpdateProgress' does not exist in the namespace 'System.Web.UI' (are you missing an assembly reference?) (\Admin\Catalog.master) and (\Admin.master)
• The type or namespace name 'UpdatePanel' does not exist in the namespace 'System.Web.UI' (are you missing an assembly reference?) (half a dozen different pages)

Ultimately, I need to be able to build the site and haven't been able to get past this so that I can proceed with the installation. Any info would be of great help. Thanks in advance.

I had similar problems until I changed the target framework in the VS property pages to .net 3.5 instead of 4.0.

Perfect...that worked! Thanks so much!
