[Bug] Null Reference Exception Thrown in RegisterCache on Mac

[trwalke]

Adding P1 as this is throwing a null ref

I seem to have found the issue. When the StorageCreationPropertiesBuilder was being created I needed to add the service and account name using

WithMacKeyChain(
    "msal_service",
     "msal_account");

After I added this the issue went away. This also explains why the issue was only appearing on mac

@jfullerton44 - looking at the stack trace above, I don't think you are using a recent version of the library.

Microsoft.Identity.Client.MSAL.Extensions is currently at version 2.18.8 and MSAL itself is at 4.35.

MsalCacheStorage.ClearCore was removed by this commit, exactly 2 years ago.

Can you please upgrade to latest versions of MSAL and cache ext and try again?

[jfullerton44]

I updated MSAL to 4.35 and Extensions to 2.18.8 and this is the stack trace now

Yes, but please add something more descriptive than "msal_service" / "msal_account". Use the name of your app. Open KeyChain app on mac and see how the data is stored there and how these labels are used.
