If you see unusual diffs in this PR, please help fixing them via suggestions. I would greatly appreciate it.

API changes in my areas LGTM. CC. @dakersnar

Mostly just the nullability annotation fixes

[JeremyKuhne]

@KlausLoeffelmann can you sanity check the WinForms changes you made here? Thanks!

[KlausLoeffelmann]

New WinForms CommandBinding and DataContext APIs look OK.

[RussKie]

System.Windows.Forms.* look good 👍

@KlausLoeffelmann @dreddy-work to confirm

[David-Engel]

System.Data looks good.

[buyaa-n]

System.Runtime.Versioning, System.Reflection, System.Reflection.Emit
changes LGTM

[bartonjs]

The methods shouldn't show as deleted.

Suggested change

	- public HMACMD5();
	+ [UnsupportedOSPlatformAttribute("browser")]
	+ public HMACMD5();
	+ [UnsupportedOSPlatformAttribute("browser")]
	public HMACMD5();

It's not showing up as deleted. AsmDiff shows the whole API as diffed when a new attribute decorates it.

[carlossanlop]

Same issue as with classes dotnet/arcade#10982

[bartonjs]

It's not showing up as deleted.

On net, it isn't, no. But to a casual interpretation by a human, it is, since there's a - line for it.

[bartonjs]

The content of System.Security.* and System.Formats.Asn1 looks correct to me; but the attribute-only changes are showing as very noisy diffs, suggesting we removed a lot of methods. Those diffs really need to be cleaned up.

System.Text.Json & System.Linq changes LGTM

[krwq]

System.Text.Json LGTM

[tommcdon]

System.Diagnostics LGTM

@bartonjs I can apply your suggestions for APIs that only had their attributes changed, but note that this is something that affects many APIs and has been happening with AsmDiff for a long time. I really don't think this is worthy of this much attention and the priority seems low.
