I fixed it. The problem is with the library SqlServerSpatial.dll. Download this file SQL Server System CLR Types from http://www.microsoft.com/download/en/details.aspx?id=8824. Extract the files. Copy SqlServerSpatial.dll to system32.

This is all the trace:

[BadImageFormatException: An attempt was made to load a program with an incorrect format. (Exception from HRESULT: 0x8007000B)]

Microsoft.SqlServer.Types.GLNativeMethods.GeodeticIsValid(GeoMarshalData g, Boolean& result) +0

...

Thanks for you quick response.

The problem is in .NET applicacion not in SQL server. I think it's a problem with 32 / 64 bits library version.

Thanks again and best regards,
