@marcpopMSFT @MiYanni I have pushed a change to unblock the build. Could you help to review it?

[marcpopMSFT]

Did you try making Equals and GetHashCode readonly? Seems like that's what the error message itself suggests.

[v-wuzhai]

There are two reasons why I am doing this fix:

1: IDE0251: Member can be made 'readonly', Source: https://github.com/dotnet/docs/blob/main/docs/fundamentals/code-analysis/style-rules/ide0251.md?plain=1

2: To maintain the same processing as other branches. For example: https://github.com/dotnet/templating/blob/main/src/Microsoft.TemplateEngine.Utils/ListExtensions.cs#L62

But I still made the change, because it looks more concise. BTW, in order to maintain consistency, I want to confirm that do we need to make the same change to the other branches?

I just realized that this PR is for 7.0.2xx which is now out of support. I'll go ahead and close it and we can check if the 0251 change is needed in other branches when they fail.
