I have a form from which the user will be able to enter the latitude and longitude of a certain point on the map. The data will be input as string values. I did some research and found out from various sources that the Entity Framework doesn't support geography data types.
Thanks in advance!
In fact Entity Framework 5 components that are shipped with .NET Framework 4.5 do support spatial types. Take a look at this walkthrough.
EDIT With EF6 you can use spatial types on both .NET Framework 4 and .NET Framework 4.5
