[chuongmep]

Purpose

• Resolve problem support update and track modify dependencies.

Description

#47 #
New Process :
System.Runtime.Loader.AssemblyLoadContext
• With .NET Core, there is only a single AppDomain
• In .NET Core 3, Contexts were introduced to replace AppDomains
• They are not a security boundary
• Load contexts are named, there is no "Current" as it was for AppDomains
• Almost zero-cost in accessing code in a different context
Main use cases:
• Ability to unload addons/plugins from the AppDomain
• Controlling the resolution (probing) of addons assemblies and native dlls
• Isolating and using different versions of the same addons
