 IMPORTANT VERSION CONSTRAINTS:
-- System.Threading.Tasks.Extensions must not be updated beyond version 4.5.4
+- Can't reference any library requiring System.Threading.Tasks.Extensions must not be updated beyond version 4.5.4
   Reason: The VS2019 extension will fail due to a transitive dependency conflict between
           Compilers.Services.Unsafe and System.Collections.Immutable.
+- Can't update Polly beyond version 7.2.4 because of dependency conflicts with System.Threading.Tasks.Extensions.
