SQL Server sys.objects and Entity Framework

SQL Server 2005 and later stores metadata in the sys tables (sys.objects, sys.columns etc.)

Using Entity Framework 4 in 开发者_运维技巧Visual Studio 2010 is it practical to generate a model on these sys tables as a way of working with the metadata? My intent is to use it read-only.

Probably easier to use the INFORMATION_SCHEMA views for this. My guess would be that they are ignored by the EF Framework. However, you could wrap them in your own views and access them that way.
