Is the Grain File Storage Example Still Valid in Orleans 9?

[zeus82]

Im trying to test a very specific use case and I was hoping to some a simple file based grain storage solution. I found this page: https://learn.microsoft.com/en-us/dotnet/orleans/tutorials-and-samples/custom-grain-storage?pivots=orleans-7-0, but when I copy the code, I get this error:
'IServiceCollection' does not contain a definition for 'AddSingletonNamedService' and no accessible extension method 'AddSingletonNamedService' accepting a first argument of type 'IServiceCollection' could be found (are you missing a using directive or an assembly reference?)

When I tried looking for information about AddSingletonNamedService I brings me to https://learn.microsoft.com/en-us/dotnet/api/orleans.runtime.keyedserviceextensions.addsingletonnamedservice?view=orleans-7.0. Changing it to Orleans 9 doesn't seem to work, it just goes back to 7.

So I guess my question is - is that example still valid for Orleans 9? If not, is there a newer example I could follow?

NamedServices were used in Orleans before keyed services were added in .NET 8. You can now use AddKeyedSingleton instead.

Other than that, the example should still be valid. The documentation should be updated to reflect this change though.

That works thanks!
