Visual Studio 2005 does not use project files, so Iron Speed Designer does not generate them for Visual Studio 2005 or 2008 (.NET Framework 2.0 / 3.0 / 3.5) applications. To open a generated application in Visual Studio, open it as a “web project”.
Note: Iron Speed Designer does not create a .SLN file (“solution” file), because Visual Studio .NET automatically creates one if you open any Visual Studio project file.
