Commented Issue: If spatial types cannot be loaded we should tell it to the user instead throwing an exception without message. [3]

If Microsoft.Sql.Types.dll assembly is not present DefaultSpatialServices will throw NotImplementedException without any error message. It is hard to figure out why the exception is thrown and how to fix it - vide:

Also the exception probably should not be NotImplementedException
Comments: Nevermind. using nuget Install-Package Microsoft.SqlServer.Types did the trick
