Non-generic version of Create method

[dhilgarth]

Is there a simple way to create an anonymous instance from a Type instance?
Looking through the code, I came up with this:

    public static object Create(this ISpecimenBuilder builder, Type type)
    {
        return new SpecimenContext(builder).Resolve(new SeededRequest(type, null));
    }

Is this correct? Is there a simpler way to do it? If not, would it be benefical to add this to AutoFixture?

Perhaps this might help:

public static object Create(this Fixture fixture, Type type)
{
    var context = new SpecimenContext(fixture.Compose());
    return context.Resolve(type);
}

The code is from from this post by @ThomasArdal.

Thanks. What's the benefit of calling Compose?

[ThomasArdal]

Correct. I originaly wrote about this here: http://thomasardal.com/non-generic-createanonymous-method-for-autofixture/

But! Fixture were changed in AutoFixture 3.x. You now simply need to do this instead (no Compose):

public static object Create(this Fixture fixture, Type type)
{
  var context = new SpecimenContext(fixture);
  return context.Resolve(type);
}

Looks exactly like what I have - just with the difference that you use Fixture instead of the more general ISpecimenBuilder. As far as I can see there is no benefit in constraining this extension method to Fixture as the only constructor of SpecimenContext takes an ISpecimenBuilder.
Am I missing something?

[ThomasArdal]

You are right. Fixture now implements ISpecimenBuilder. Constraining it to Fixture, doesn't make sense :)

Thanks for the confirmation! :)
