Answer 1

You can add a generic function to your repository, like this:

public T FindBy(Expression<Func<T, bool>> predicate)
{
    return Context.Set<T>().Where(predicate).FirstOrDefault();
}

And then in your program, call it like this:

var person1 = MyGenericRepository.FindBy(r => r.FullName == "John Smith");
var person2 = MyGenericRepository.FindBy(r => r.Email == "jane.smith@gmail.com");

Assuming you have FullName and Email in your DB Set.
