Dependency injection, inject with parameters

Question

I\'m using vNext implementation of DI. How to pass parameters to constructor? For example, i have class:

public class RedisCacheProvider : ICacheProvider
{
         


        

Answer 1

You can either provide a delegate to manually instantiate your cache provider or directly provide an instance:

services.AddSingleton(provider => new RedisCacheProvider("myPrettyLocalhost:6379"));

services.AddSingleton(new RedisCacheProvider("myPrettyLocalhost:6379"));

Please note that the container will not explicitly dispose of manually instantiated types, even if they implement IDisposable. See the ASP.NET Core doc about Disposal of Services for more info.
