Rhino WIP Feature: Get ready for .NET 7!

I noticed this tweet recently:

Many CPUs, even older ones use/have AVX. Is there any chance that Rhino can make use of it, now that it is accessible through the new .NET version?

One specific case of a “free” performance improvement was when optix for raytraced was introduced. That speedup felt magical to me. Now the move to the newer cyclesX with RH8WIP brings jet another very noticeable improvement - no new hardware/investment required. With that in mind I thought it would be really nice if you guys could find a way to utilize AVX capable hardware through the new .NET. I know it probably won’t be related to rendering but hopefully there is something in Rhino that would benefit from AVX. Maybe something Grasshopper related?

Ok is where any example with a plugin using net 7.0. I run into some issues. Is where any Rhinocommon complied against net 7.0?

so, what is the Default value? is it netfx or netcore?

.NET core 7 is the current default in Rhino 8: Rhino - Moving to .NET 7

Rhino 7 is .NET Framework 4.8

Thank you clarifying,
It is going to be a windows vista moment for some plugins, especially for the older ones that are no longer in development, I guess time to move on.

By default, that could be. We are trying to improve the information when a plugin does not load so that some people might be able to switch the runtimes if needed.

Is it possible at runtime to test whether Rhino is running in framework or core?
ie some property in Rhino.Runtime or similar?

Sorry if I’ve overlooked it.



I believe Environment.Version would let you know


Thanks, hadn’t found that. Works great.

Oh… does that mean it only supports one runtime at a time?

So if the user wants to run a legacy 4.8 plugin and set their version of 8 to use the 4.8 runtime, then a 7.0 based plugin would stop working?

Dose .NET 8 come with Rhino 8 too? .NET 8 (LTS) is in RC1 now, seems like it will release next month.

No, we plan on sticking with .NET 7 for Rhino 8. We will explore the next version of .NET with Rhino 9.
