Initializing a new cacheProvider instead of removing the keys from the existing cacheProvider gives inconsistent behavior to how Remove(key) works.
E.g. if the CachingService was instantiated using any of the constructors except CachingService(), then calling RemoveAll will change the underlying cacheProvider to a DefaultCacheProvider.

You are right.
I made this PR because I use dependency injection to create a CachingService, and the PR #91 doesn't work correctly with DI.
I think it's best to abandon this PR, and edit PR #91 so dependency injection code (asp.net core, ninject) works correctly.

Yeah this sort of change will need to incorporate DI so will close in favour of #91

I am still thinking about if, and how, LazyCache should support a delete everything feature. In the meantime I have added 2 ways of achieving the same thing without changes to LazyCache to the docs.
