A new version of Enterprise Library has been released by the Patterns & Practices team @ Microsoft. This library has been extended with an Integration Pack that focuses specifically on the development patterns and architectural guidance of the applications running on Windows Azure.
So what is in this package? The most important things are the following:
The recommended way to obtain the Enterprise Library Integration Pack for Windows Azure is as NuGet packages. Alternatively, you can download self-extracting zip files with binaries, sources (including tests) and the reference implementation from MSDN. The configuration tool is available as a Visual Studio extension package (VSIX) from the Visual Studio Gallery.
Definitely worth to download!
