Application cannot load Microsoft.SqlServer.Types Version 13

I am having a problem that many people have had before but none of the existing answers seem to work for me.

When I deploy my ASP.NET project I get an error in the event log saying

Could not load file or assembly 'Microsoft.SqlServer.Types, Version=13.0.0.0, Culture=neutral, PublicKeyToken=89845dcd8080cc91' or one of its dependencies. The located assembly's manifest definition does not match the assembly reference. (Exception from HRESULT: 0x80131040)

To try to rectify this I installed the Nuget package:

PM> Install-Package Microsoft.SqlServer.Types

This didn't work and I get the same error. So then I followed the readme and used Loader.cs to load the files. Again, same problem. What is happening and why don't the usual solutions fix it?

One thing I did note is that my Microsoft.SqlServer.Types.dll is version 11 not 13? If it makes any difference our database is SqlServer 2016 and our machine is running Windows Server 2008

The way I solved this was to to set the SqlServerTypesAssemblyName in my app. I currently set it in my EntityContext constructor [that inherits off DbContext] to ensure its always set

SqlProviderServices.SqlServerTypesAssemblyName 
            = "Microsoft.SqlServer.Types, Version=13.0.0.0, Culture=neutral, PublicKeyToken=89845dcd8080cc91";

Note your version may want to be different.
