ASP.Net AppFabric Cache missing Flush/Clear and Count/GetCount methods?

Question

I am trying to convert a solution using EntLib into using AppFabric caching. By help of a few extension methods this is a fairly pain-free process.

See my previous answer for my speculation as to how the cache works internally when you don't specify a region, and how you can get the count of objects that aren't in a named region.

We can build a Flush method using the same technique:

public void Flush (this DataCache cache)
{
    foreach (string regionName in cache.GetSystemRegions()) 
    {     
        cache.ClearRegion(regionName) 
    } 
}

As I said there, I think named regions are probably the way to go - it seems to me that using them solves more problems than it creates.
