If you want to use MsSqlSpatial you need to install an addition to SqlServer.

If you want to use SqlServer2008, use SqlServer2008 provider

sandimchk, it is advised to compile sharpmap yourself. Grab yourself a copy of the source and replace the sqlserver2008.cs file by the one provided in the patch
