Entity Framework June 2011 CTP and SQL Server 2012

Question

I have a spatial model definition which used to be working with SQL Server 2008 but not with 2012 anymore.

I don't know why but I can't get it working...

model.Location = DbGeography.Parse("POINT(" + model.Latitude + " " + model.Longitude + ")");

I am getting this exception:

System.Reflection.TargetInvocationException was unhandled by user code
HResult=-2146232828
Message=Exception has been thrown by the target of an invocation.

Any help ?

Answer 1

It was really not understandable with this error but the problem was the localization of my computer.

It was expecting a dot (.) rather than coma (,) as my decimal symbol. I've just set it from Start>Control Panel>Region and Language>Additional Settings and voila. It is working now.

Thank you for your helps.

Unistall the CTP and install .NET Framework 4.5 beta. If you still have the problem update the thread.
