Using generic classes with ObjectDataSource

Question

I have a generic Repository class I want to use with an ObjectDataSource. Repository lives in a separate project called DataAccess. According to this post

Answer 1

I know this is an old post but I have recently had this problem myself. Another solution would be to replace the inheritance with object composition, e.g.

[DataObject]
public class DataAccessObject {
    private Repository _repository;

    // ctor omitted for clarity
    // ...

    [DataObjectMethod(DataObjectMethodType.Select)]
    public MessageCategory Get(int key) {
        return _repository.Get(key);
    }
}

This way the ObjectDataSource doesn't know about the repository because its hidden within the class. I have a class library in my facade layer that is a perfectly reasonable place to put this code in the project I am working on.

In addition, if you are using Resharper and interfaces, its possible to get Resharper to do the refactoring using Resharpers "Implement using field" function.
