Microsoft has reduced the .net runtime by over 85%. Applications using the .net framework should be quicker to download and install, said Microsoft.
The service packs are intended to help developers build Windows applications quicker. They include tools such as the .net Framework Client Profile, which Microsoft said would enable developers to deploy Windows-based applications faster.
Scott Guthrie, corporate vice-president of Microsoft's .net Developer Division, said: "The .net Framework Client Profile significantly speeds up the installation of Windows and enables a much more consumer-friendly experience. This is a huge step forward for the more than 4 million .net developers worldwide."
