Issue with Net 5.0

[Chessnut1071]

Okay, I see the advantage of bit boards, at least on pseudo move generation; however, Net 3.0 doesn't support bit scan forward. So, I took the advice of some on this board and target Net 5.0. I got the intrinsic bit operations working and it runs 9.9x faster than my code work around. The problem is Net 5.0 doesn't update my labels and the WPF doesn't support some of my Win forms code. I need the speed, but, I also need my graphics and forms code. Am I missing an assembly or namespace? It seems like 100s of other programmers are having the same issue with Net 5.0. Does Net 6.0 have better support for Win Forms?

Again for Chessnut: Bitscanforward (ie TrailingZeroCount) could be used since Visual Studio 2015 and .net framework. For Core its also there:
System.Runtime.Intrinsics.X86.Bmi1.X64.TrailingZeroCount(value);

WPF doesn't support some of my Win forms code.

That's odd. You should be able to just host any system.windows.forms form with the WindowsFormsHost WPF control. If you can't load your form within a WPF host, that may be because you use different frameworks for the assembly containing the form and the WPF assembly.

FRUSTRATION!
Been there, done that, have the t-shirt. I still get the same error: Net 5.0 C# Wpf

using System.Windows.Forms; CSO234 error: Type or namespace "Forms" does not exist in the namespace System.Windows

}

Perhaps Net 5.0 doesn't like me.

The namespace should be System.Windows.Forms.Integration.

You're probably missing a framework reference to WindowsFormsIntegration (and to System.Windows.Forms, apparently).

Status: bit scan forward is working fine in Net 5.0; However, my labels are not updating on the Grid. It seems my program can no longer update, or refresh, like I could in Windows Forms. I think this is a WPF issue which probably has a simple solution. There are no errors or warnings, just no update to the labels I use for debugging. Net 5.0 is brand new to me and you can no longer refresh a control in WFP. I would go back to my Windows forms, but, the intrinsic bit operations are over 9x faster than my C# code work around. It seems like 100s of other programmers are having similar issues, most converting to Net 5.0 from earlier version too. This seems so simple, how do you refresh controls in WPF?

stop using 5.0

start using 6.0

Okay, got it working in Net 6.0, including trailing zeros and the rest of the intrinsic bit operations. Net 5.0 drove me bananas. Thx for all the responses.

It appears Net 6.0 is approximately 18% faster on than Net 5.0 on most of my pseudo move generating code, was not expecting that big of an increase.
