                                          | .Net 3.5 uses mscorlib.dll and system.dll from the 2.0 folder under Microsoft.Net\Framework, that is why you see version 2.0.50727 when you look up that DMV. But you would be able to use the .net 3.5 features if you have it on your system.From what I understand, SQL 2012 requires .net 4.0, and Net 4.0 has its own versions of mscorlib.dll and system.dll. So if you were to query sys.dm_clr_properties in SQL 2012, I assume you would see 4.0.30319 (or some such).There is a little bit of information about the various .net versions and their relations to SQL CLR here, but it is a little dated: http://www.sqlskills.com/BLOGS/BOBB/post/On-SQL-Server-and-NET-40.aspx  |
