I've installed VWD to a brand new Vista machine. I've installed SP1 for VWD and installed the Vista service pack for Visual Studio Express. I've set VWD to run as an administrator.

All appears fine until I try to use a dll in the bin directory.

The dll appears in the solution explorer and I can even use the object inspector to look at the classes available and the methods etc.

But if I try to reference the classes/namespaces in the code, they just aren't there. They don't appear in auto complete and building the solution gives a compile time error stating that the namespaces/classes can't be found. I've tried using "Add reference" to add the dll to the project, but have had no success.

The exact same code and dlls work fine under XP.

I've even tried setting the application compatibility to "XP service pack 2" but it has made no difference.

Can anyone tell me if I've missed something really obvious?

Thanks.

Could you be more specific?

Do you mean under assemblies?

 I've tried that and I get the error

 Error 2 Could not load file or assembly ... or one of its dependencies. The module was expected to contain an assembly manifest.

EDIT: Actually I've just tried it in VWD 2008 and it's exactly the same. Could it be the 3rd party .dll that is the problem under Vista?? This all works fine in XP.

Further more, I'm trying to use the AJAX control toolkit, but when I try and add the controls to the toolbar from the dll, I get this error.

 "'C:\Users\crashby\Documents\Visual Studio 2005\WebSites\AJAXEnabledWebSite4\Bin\AjaxControlToolkit.dll' is not a Microsoft .NET module."

This is terrible. My brand spanking new PC is useless for development. 

Does everyone else use VWD 2005 on vista without issues?

Solved it! I turned off the internet security that shipped with the PC and everything works. How helpful of the manufacturers...
