A while ago, I wrote a blog post regarding Test Data Builders Refined. Earlier this week, I wrote a very simple base class that provides an implicit cast operator for the builder class:

public abstract class TestDataBuilder<TSubject>
{
    public abstract TSubject Build(); 

    public static implicit operator TSubject(TestDataBuilder builder)
    {
        return builder.Build();
    }
} 

Even I can’t get it more complex than this .
