.NET analysis no more requires MS framework assemblies to be packaged

When you are packaging .NET source code there is no more requirement of adding MS framework assemblies as resource package. But while doing a package you will have several alerts related to System assemblies as shown in the screenshot below (Microsoft run time library alerts)but you can ignore these alerts and go ahead in delivering the packages.

The reason why we do not require to package MS framework assemblies is because from .NET extension 1.1 and above we are already delivering the extension under third_parties folder , see this official documentation link for more details: https://doc.castsoftware.com/display/TECHNOS/.NET+-+Prepare+and+deliver+the+source+code

Assemblies (.NET Core and .NET Framework assemblies) present in the extension in the below location

So, as advised when using .NET 1.1 or above version we should not package the framework assemblies and simply making the delivery bulky by keeping the assemblies.
