Hi,
The framework supports Transient and Singleton lifestyles for dependencies. I have a domain service whose lifestyle I would like to configure to be Per Request, as this domain service is heavily used and I want to reduce the number of unneccessary instantations of this domain service for each request.
I've tried this but it does not work. The dependency still behaves as Transient.
Please advise on how I can configure dependencies to be per request.
Thank you, Justin

Hi @justinidsza
You can try using ASP.NET Core's scoped dependency injection, something similar to below;
using var scope = _serviceProvider.CreateScope(); var coreObjectManager = scope.ServiceProvider.GetRequiredService<CoreObjectsManager>();Does that work for you ?

Hi @ismcagdas,
Thanks for the response.
Unfortunately, I don't think that will work us. It looks like I would need to inject IServiceProvider into dependencies, which would be the Service Locator pattern. I consider that pattern to be an anti-pattern.
I was under the impression that MsScopedLifestyleManager would work for ASP.NET Core, but If I look at the source code it seems that there is no active / current scope.
I will investigate if I can implement a custom lifestyle manager based on HttpContext.
Regards, Justin

There is another interface named
IPerWebRequestDependencywhich registers the class with the lifestyleMsScopedLifestyleManager. Maybe you can give it a try.
