I've been looking at the June CTP build for a few days now. Only a small number of the promised features are actually available in this early build. One of the features that is available is DMF (Declaritive Management Framework). This allows organisations to define how their SQL Server(s) should behave by defining policies. So for example if I want all my databases to have certain settings or tables to have specific naming conventions I can define policies that eforce these behaviours. However there is a bug in this CTP build that will result in a error when you attempt to use the feature. This is a known issue and Dan Jones who is a PM in the SQL team explains the problem and has a simple fix in his blog post here. All you need to do is run the folllowing:-

 C:\Program Files\Microsoft Visual Studio 8\SDK\v2.0\Bin\sn.exe -Vr Microsoft.SqlServer.DmfSqlClrWrapper,89845DCD8080CC91
