Replace assembly at runtime
-
Hi, I have a .NET C# application that contains many different assemblies. My start up project contains all assemblies as references, so when I build the application all these assemblies are copied to output directory. Is it possible to replace one of the assemblies at runtime, if it exist a new version of that assembly? Best regards Olof

Short answer: No Shortish answer: If you get to it early enough (before any types (or types that reference the types) are instantiated that reference the dlls) you can overwrite them. Long answer: If you need more than the above gives you like being able to swap the types after they have been used you need to create a seperate AppDomain and load the dlls into that. If they get updated you can destroy the AppDomain and create a new one with the new dlls. It all depends on what you are trying to achieve.

One way would be to load the assemblies using Reflection. That way, if an assembly changes periodically, you will get the latest

Hi, a lot of the types declared in the assembly I want to update at runtime are used both in this assembly and in other assemblies. And since a lot of people are working in the project at the same time it's not easy to make a bigger reorganization of the source files.

The traditional way to approach this would be to use Dependency Injection to inject the appropriate DLL at runtime. The best way to do this is to not hardcode your type references, but rather you would work against interfaces which the concrete classes would implement. There are many benefits to doing this such as creating more testable objects, improving the loose cohesion of the system, etc.
