Options pattern in a shared class library
Hello all, I am looking to use options pattern in a shared class library, but I am not sure how should I go about it. The project structure is something like this:
What I need is to somewhat use options pattern in, say,
Class_library_2 (or at least have access to the configuration provider in any way), but I am unsure what would be the proper way to do this.
If I register the config in the Startup.cs of the Api_1 web project, those won't be available from Api_2.
Should I create the option classes and register the config in both projects?
Any hints or advice? Thanks a lot!10 Replies
normally, you'd make an
IServiceCollection extension method inside the package that needs the configuration (ie Class_lib_1)
something like AddClassLib1();
if you want to access the IConfiguration, thats fine and can be done in a few ways, including passing it into that methodSo I need to register the config in both projects, right? Where do I define the option classes?
Something like this? https://learn.microsoft.com/en-us/dotnet/core/extensions/options-library-authors#iconfiguration-parameter
yep, exactly like that
Thank you. I will attempt to follow that example, still learning 😅
One more question, that still is not clear to me: where should I define the option classes?

you would define the option class in your library
that way any other project that uses it has access to it
