Manually Trigger Background Refresh

[Turnerj]

There is one more thing I am wondering about. Is it possible to make a function that can manually refresh the data in the background? Same as with the staleAfter parameter but manually.
cacheStack.RefreshValue(key, function?);

More-or-less, could expose it like so:

cacheStack.RefreshCache(cacheKey, valueFactory, cacheSettings);

public void RefreshCache(string cacheKey, Func<T, Task<T>> valueFactory, CacheSettings cacheSettings)
{
    _ = RefreshValueAsync(cacheKey, valueFactory, settings, CacheEntryStatus.Forced);
}

Would need to create a second implementation that has Func<T, TContext, Task<T>> valueFactory for CacheStack<TContext> support though.
