7 years ago Pretty good question. I had to play with the default ASP.NET Core DI a little bit to figure that out.
First of all, you probably should not use transient instances and use singleton instead for CacheManager.
Then, in your code, t.GetType() gives you the type of IServiceProvider, that is what t is. So that totally wouldn't work. In that overload, you do not get to the Type requested. And there is no overload to do so.
Instead what you can do, and what actually works pretty well:
- You register the cache configuration as singleton
- You register the open generic interface of cache manager and the implementation type for it, which is
BaseCacheManager<>also as open generic
var config = ...build cache configuartion...
/* add it to the services */
services.AddSingleton(config);
/* add the cache manager interface and impl type as open generics */
services.AddSingleton(typeof(ICacheManager<>), typeof(BaseCacheManager<>));Later, in your controller for example, you can constructor inject a CacheManager instance
public ValuesController(ICacheManager<string> cache, ICacheManager<int> intCache)
{
this.cache = cache;
this.intCache = intCache;
}Works fine! Let me know if you have any issues and, in general, this kind of questions are probably more suited for stackoverflow ;)

Hello,
I have tried to find some good examples of registering CacheManager in ASP.NET Core with DI. Is there any examples of this , cause I couldn't really get it working with the "Built-In" DI. So wanted to ask if I'm missing something or do a need to use StrucutureMap, To be able to register CacheManager Generic?
This is the non-working code I wrote:
That throws an error
Open generic service type '{typeof(IEnumerable<>)}' requires registering an open generic implementation type.
