"..." cannot implement an interface member because it is not public

Question

public interface IDatabaseContext : IDisposable {

    IDbSet<MyEntity1> Entities1 { get; set; }

}

public class MyDbContext : DbContext, IDatabaseContext {

    IDbSet<MyEntity1> Entities1 { get; set; }

}

Can't compile because of the error described in here: http://msdn.microsoft.com/en-Us/library/bb384253(v=vs.90).aspx

However, this makes no sence since the interface obviously IS public. What could be the error here?

Answer 1

When implementing an interface member in the class, it should be public

See: Interfaces (C# Programming Guide)

To implement an interface member, the corresponding member of the implementing class must be public, non-static, and have the same name and signature as the interface member.

public class MyDbContext : DbContext, IDatabaseContext {

    public IDbSet<MyEntity1> Entities1 { get; set; }
}

Or as @Marc Gravell said in comment you can do Explicit interface implemenation, More could be found at this answer
