Microsoft just recently announced the new Microsoft .Net logo. This will replace the old logo that has been hanging around for the last 8 years.
We needed a logo that was in sync with the key values that we want .NET to stand for: consistency, robustness and great user experiences. We also wanted a logo that conformed to the design principles that are driving Microsoft’s brand identity evolution and is reflected in newer brands such as Silverlight, Surface and more. Finally, we needed a logo that is more strongly aligned with the portfolio of brands that .NET is most strongly aligned with: Silverlight, Visual Studio and the AppPlat server products.
