Unused private members for targets in Visual Studio (IDE0051)

[robertcoltheart]

Visual studio shows certains targets as being "unused", when clearly they will be used as part of a Nuke build.

I'm a maintainer over at Machine.Specifications and we have the same issue with using delagates for test targets.

I'm aware that you can add supressions in code attributes / editorconfig etc, but I'm just wondering if there are any thoughts or ideas as to how you could suppress IDE0051 at the source instead? I've toyed with the idea of a source analyzer (Roslyn) to suppress the diagnostic or a source generator to "use" the delegates to prevent reporting the diagnostic.

Any thoughts?

Personally, I'm using JetBrains annotations to mark code entities as implicitly used. But this should really only be necessary for targets that are neither a dependency or the default target. I.e., only targets that are manually invoked are a concern. Otherwise, there should always be some kind of usage.
