Can you switch the error list filter from “Build+Intellisense” to “Intellisense” and try right clicking from error list again? Note that Build diagnostics are not suppresible. Also note that you can suppress diagnostics by double clicking in error list and then in the editor invoke the light bulb menu with Ctrl + . Keys to see the suppression menu items.

Ctrl + . key not provide Supress CA..... =>menu items

if I use [SuppressMessage("Microsoft.Naming", "CA1724:TypeNamesShouldNotMatchNamespaces")] in code it works.

[xmarshal]

what can I do next?

Does this work if you downgrade CA1724 to a warning instead of an error?

The issue seems to be CA1724 and CA1812 are both compilation end analyzers, and we don't run them in live analysis anymore, primarily because they are expensive for live analysis and need the whole compilation to be analyzed before diagnostics are reported. https://github.com/dotnet/roslyn-analyzers/issues/2267 tracks rewriting CA1812 as a non-compilation end analyzer, which should fix the issue for that diagnostic. For CA1724, unfortunately you will have to manually add suppressions.
