BPM Tuple Error

Good morning! Hope everyone is well. When I make any change to a BPM (working on an upgrade) I get a strange error about tuples. It doesn’t matter what I change. If I put in a string, and comment it out, the error still occurs (heck even when I simply add a space, the error occurs).

The error: “Feature ‘tuples’ is not available in C# 6. Please use language version 7.0 or greater.”

I was hoping someone could shed some light on this. Seems to be a server/upgrade issue.

two facts I know from a few years ago.

  1. C# Tubles is a “new feature” that was released. https://docs.microsoft.com/en-us/dotnet/csharp/tuples
  2. There were developers who were excited about this, and were hoping to use it in future releases.

Beyond that, I dont know what version tuples started getting used… but it sounds like your installation is not at the correct versions of software. You should probably contact Tech Support with all your version information.

I’ve used Tuples in Epicor 10.1.500.46 and we upgraded from 10.1.500.46 to 10.2.300.10 just fine.
