I need to add cache functionality and found a new shiny class called MemoryCache. However, I find MemoryCache a little bit crippled as it is (I'm in need of regions functionality). Among other things I need to add something like ClearAll(region). Authors made a great effort to keep this class without regions support, code like:
if (regionName != null)
{
throw new NotSupportedException(R.RegionName_not_supported);
}
flies in almost every method.
I don't see an easy way to override this behaviour. The only way to add region support that I can think of is to add a new class as a wrapper of MemoryCache rather then as a class that inherits from MemoryCache. Then in this new class create a Dictionary and let each method "buffer" region calls. Sounds nasty and wrong, but eventually…
Do you know of better ways to add regions to MemoryCache?

I know it is a long time since you asked this question, so this is not really an answer to you, but rather an addition for future readers.
I was also surprised to find that the standard implementation of MemoryCache does NOT support regions. It would have been so easy to provide right away. I therefore decided to wrap the MemoryCache in my own simple class to provide the functionality I often need.
I enclose my code it here to save time for others having the same need!
