Unable to compile demo project due to tuples utilization

Can you provide some context for the .map expression? I’ll be able to diagnose the problem quicker if I have access to your demo. Thanks

I got a zip file ready but forgot to send it. Here it is.

Thanks. I've diagnosed the problem. Generally, a method with an auto return type that resolves to an anonymous type, such as a tuple type, cannot be used as a method reference. As you've discovered, you must instead use a lambda.

I'm addressing this issue by adding a compiler message indicating that lambda usage is required here. This change will be available in the next manifold release later in the week. Thanks for reporting this!

Hi. Is there really no way how to make it work with method reference? Method references are used a lot and it would be nice to support it.

It’s not impossible. I plan to circle back on this because there are other features such as extension methods that don’t work with method refs. The solution is similar.
