Use your autodata attribute like the XBehave Example attribute

ExampleAutoDataSpecimenBuilder.cs

public class ExampleAutoDataSpecimenBuilder : ISpecimenBuilder
{
    private readonly object[] _data;

    public ExampleAutoDataSpecimenBuilder(object[] data)
    {
        _data = data;
    }

    public object Create(object request, ISpecimenContext context)
    {
        var parameterInfo = request as ParameterInfo;

        if (parameterInfo == null)
            return new NoSpecimen();

        if (CurrentPositionGreaterThanProvidedExampleCount(parameterInfo))
            return new NoSpecimen();

        if (ParameterIsType(parameterInfo))
            return _data[parameterInfo.Position];

        if (ParameterTypesMatch(parameterInfo))
            return _data[parameterInfo.Position];

        return new NoSpecimen();
    }

    private bool CurrentPositionGreaterThanProvidedExampleCount(ParameterInfo parameterInfo)
    {
        return parameterInfo.Position >= _data.Length;
    }

    private bool ParameterTypesMatch(ParameterInfo parameterInfo)
    {
        return _data[parameterInfo.Position] != null && _data[parameterInfo.Position].GetType() == parameterInfo.ParameterType;
    }

    private bool ParameterIsType(ParameterInfo parameterInfo)
    {
        return _data[parameterInfo.Position] is Type && parameterInfo.ParameterType == typeof(Type);
    }
}

@iamkoch How do you configure this to work with autofixture and xbehave?

Extend the autodata attribute, and add this as a customisation when instantiating the fixture

@iamkoch this seems to need some constructor params, where do those come from when I try to add them to the customizations?
