What's New in This Release: [ read full changelog ]
· Bug fix to remove the need to specify ‘Persist Security Info=True’ in the connection string when using SQL authentication. This change predominantly affects users connecting to SQL Azure.
Introduction of new types to facilitate design-time tools for Code First:
· DbContextInfo can be used to instantiate and interact with a derived context as well as determine information about the origin of the connection string etc..
· IDbContextFactory is used to let DbContextInfo know how to construct derived DbContext types that do not expose a default constructor. If your context does not expose a default constructor then an implementation if IDbContextFactory should be included in the same assembly as your derived context type.
