Community Preview of the Enterprise Library 4.0 Available

The Community Preview of the Enterprise Library 4.0 is available from CodePlex.

Overview from CodePlex
This release has been adapted to work with WMI version 2.0 and version 3.5 of the .NET Framework.

Enterprise Library 4.0 has the Allow Partially-Trusted Caller attribute (APTCA) on all assemblies. This means that you can call the methods of Enterprise Library and the application blocks from an application running in a partial trust environment. You can do this with the signed assemblies provided with Enterprise Library. There is no longer any requirement, as there was in version 3.x, to recompile the source code then either use the unsigned binaries or strong-name them yourself.

The Caching Application Block has been refactored to allow developers to replace the CacheManager class with other implementations, including the ones offered by the distributed cache solution providers. This does not affect the API of the application block.

There are also additions in functionality to the Logging Application Block, the Validation Application Block, the Exception Handling Application Block. For details see the change log attached.

Build scripts are packaged under /Scripts. Run the following:

BuildLibraryAndCopyAssemblies.bat
InstallDbs.bat
RegAssemblies.bat
InstallServices.bat (optional; if you need MSMQ support et al)

Note: This community preview does not include integration with the Unity Application Block http://www.codeplex.com/unity or the integrated Visual Studio 2008 config tool. These features are planned for the final release.
