Adding an interface to a partial class

Question

I have a class that is generated by a third party tool:

public partial class CloudDataContext : DbContext 
{
    // ...SNIPPED... 
    public DbSet

        

Answer 1

Here's a quick checklist. Do the classes have identical:

• Names?
• Namespaces?
• Access modifiers?

Example:

• You decide to split an existing class into two files.
• The original file's namespace doesn't match its folder path.
• Consequently, the new class file you create has a mismatching namespace.
• Build fails.

Answer 2

IN my Case problem was that interface Method that was implemented in other part of the partial class was not compiling and C# was giving error of not implemented Method

Answer 3

The problem must be somewhere else, because you can implement interface in the other part of partial class then it's set on. I just tried following and it compiles just fine:

public interface IFoo
{
    int Bar { get; set; }
}

public partial class Foo
{
    public int Bar { get; set; }
}

public partial class Foo : IFoo
{

}

The properties probably use different types in interface and class.
