I've made a simple dll to demonstrate calling C# from Matlab. When I run with the dll built using .Net Framework 4.7.2 the call to Net.Assembly works as expected. When I call a dll built using .Net Core 3.1 I get the following error message.
"Could not load file or assembly 'System.Runtime, Version=126.96.36.199, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a' or one of its dependencies. The system cannot find the file specified."
I suspect there may be a Matlab config file that needs to be changed to support this runtime version.
Anyone else run into this problem and have solution?

Starting In R2022b, on supported Microsoft® Windows platforms, MATLAB will support loading libraries compiled for .NET 5 and higher and for .NET Core, as well as existing support for the Microsoft .NET Framework. You will be able to select a .NET environment, use the dotnetenv function.

I enquired with Matlab support last summer regarding .NET Core / Matlab interop and it is not supported although I was assured that the team were working on it. I've looked at the releases since then (R2019b and R2020a) and MATLAB/.NET core is still not supported and I have not seen any official information released by MATLAB regarding timescales for .NET core support.
This is a bit disappointing as Microsoft are recommending .NET Core for new developments. In fact last week they announced .NET 5 preview 1. As .NET 5 is the next major release of .NET and will unify .NET on a single platform and that this is what they are recommending that all new applications are built with it, it is surprising the Matlab have not got round to supporting .NET core, particularly as it now several years old.

As Robert mentioned R2019b, the MATLAB Interface to .NET does not support .NET Core. The developers are considering adding support for this in a future MATLAB release. Please find the current system requirements for using the .NET Interface below.

There is nothing in the release notes about .NET Core. Microsoft has announced .NET 6 preview 2 now. It's not obvious that anyone from Matlab looks at these kind of posts very often or has much current interest in supporting .NET Core judging by their level of engagement.
