How do I set SizeLimit when using asp.net core DI? #151

Closed coderdnewbie closed 3 years ago

coderdnewbie commented 3 years ago

I am building a webapi and want to use LazyCache. Can the SizeLimit be set? The only way that is shown to do this is:

IAppCache cacheWithSizeLimit = new CachingService( new MemoryCacheProvider(new MemoryCache(new MemoryCacheOptions { SizeLimit = 5 })));

However, I am puzzled how to do this using the DI mechanism. How do I set the SizeLimit when asp.net is making the IAppCache instance?

I found this:

services.AddMemoryCache(options => options.SizeLimit = 1000);

Would this work for lazycache, I can’t see how to do it. Please help.

Register it in DI with a factory class or factory delegate.
