✨ DataAnnotations support for specimen factories

[aivascu]

Description

Allow the use of .NET data annotation attributes to be used when specifying a factory function for a specimen.

Example

fixture.Customize<Version>(o => o
    .FromFactory(([Range(0, 2)] int major, [Range(0, 10)] int minor, [Range(0, 100)] int patch) =>
    {
        return new Version(major, minor, patch);
    }));

fixture.Customize<Version>(o => o.FromFactory(CreateVersion)));

static Version CreateVersion([Range(0, 2)] int major, [Range(0, 10)] int minor, [Range(0, 100)] int patch)
{
    return new Version(major, minor, patch);
}

Tasks

• Confirmed feature idea with maintainers in support forums

More Information

Currently the FromFactory method does not use the usual AutoFixture pipeline, but rather uses the delegate directly to create the new specimen.
Must investigate whether it is viable to allow AutoFixture to generate values and what implications might, changing the implementation, have.
