Microsoft.Azure.Documents.Client not supported in RC2

# Issue Title

Microsoft.Azure.Documents.Client not supported in RC2

# General

I am trying to access an Azure CMOS database from webassembly and getting the runtime error

"Unhandled exception rendering component: System.Security.Cryptography.Algorithms is not supported on this platform."

Missing this functionality limits the usefulness of Blazor since I cannot write directly into my Cosmos database using Microsoft.Azure.DocumentDB.Core and Microsoft.Azure.Cosmos

The full error trace is
Unhandled exception rendering component: System.Security.Cryptography.Algorithms is not supported on this platform.
System.PlatformNotSupportedException: System.Security.Cryptography.Algorithms is not supported on this platform.
