Entity Framework – The version of SQL Server in use does not support datatype ‘datetime2’

I came across this error when I’ve generated the EDMX model (Entity Framework) using a database source that is SQL Server 2008R2 and ran it in different environment that has different SQL Version (2005).

To fix this issue:

Manually open the EDMX file using XML Editor or notepad, replace the value of ProviderManifestToken from 2008 to 2005.
