In April 2003, Microsoft introduced a minor upgrade to Visual Studio .NET called Visual Studio .NET 2003, codenamed Everett (for the city of the same name). It includes an upgrade to the .NET Framework, version 1.1, and is the first release to support developing programs for mobile devices, using ASP.NET or the .NET Compact Framework. The Visual C++ compiler's standards-compliance improved, especially in the area of partial template specialization. Visual C++ Toolkit 2003 is a version of the same C++ compiler shipped with Visual Studio .NET 2003 without the IDE that Microsoft made freely available. As of 2010 it is no longer available and the Express Editions have superseded it. The internal version number of Visual Studio .NET 2003 is version 7.1 while the file format version is 8.0.
Visual Studio .NET 2003 shipped in four editions: Academic, Professional, Enterprise Developer, and Enterprise Architect. The Visual Studio .NET 2003 Enterprise Architect edition includes an implementation of Microsoft Visio 2002's modeling technologies, including tools for creating Unified Modeling Language-based visual representations of an application's architecture, and an object-role modeling (ORM) and logical database-modeling solution. "Enterprise Templates" were also introduced, to help larger development teams standardize coding styles and enforce policies around component usage and property settings.
Service Pack 1 was released September 13, 2006.
