>With SQL Server 2012, the Web site was running ok with tables containing Spatial Data Type.

>The only think I did was to install the following two files on the Web server:
>
>Microsoft System CLR Types for Microsoft SQL Server System
>Microsoft SQL Server Shared Management Objects
>
>...and, adding this to the connection string: ;Type System Version=SQL Server 2012

>Now, the Web site is running against SQL Server 2014. Then, of course, it no longer runs. We have this:
>
>"DataReader.GetFieldType(371) returned null."
>
>So, I upgraded the project to use the new 2014 version of the above two files. I had to remove that setting in the connection string as this is no longer supported.
>
>But, the Web site does not want to run. This is the same error.

>Some says to add a reference to Microsoft.SqlServer.Types.dll in the project and deploy that to the Web site bin directory. I did that with no success.
>
>Some says to lower down the application pool to 32 bits. I did that with no success.

>Is this still working in 2014?
