Example

//Create a Primary Memory Cache with a backing File Cache
string directory = Path.Combine(Environment.GetFolderPath(Environment.SpecialFolder.LocalApplicationData), "KellermanSoftware", "NetCachingLibrary", "Tests");
SmartConfig config = new SmartConfig(new MemoryCacheProvider(), new FileCacheProvider(directory));
            
//Specify UserName and LicenseKey for Licensed Mode
//config.UserName = "my user name";
//config.LicenseKey = "my license key";
            
//Instantiate the cache
SmartCache cache = new SmartCache(config);
            
//Build parameters for the report
int month = DateTime.Now.Month;
int year = DateTime.Now.Year;
            
//Get the cache key based on the report parameters
string cacheKey = cache.BuildCacheKey("MonthlySalesReport", month, year);
            
//Attempt to load the report from the cache
List<ReportDetail> report = cache.Get<List<ReportDetail>>(cacheKey);
            
//Not found in the cache
if (report == null)
{
	//Load the report from the database
	report = ReportLogic.MonthlySalesReport(month, year);
            
	CacheItemPolicy policy = new CacheItemPolicy()
	{
		AbsoluteExpiration = DateTimeOffset.Now.AddMinutes(20),
		SlidingExpiration = SmartCache.NoSlidingExpiration
	};
            
	//Save to the cache in the Default region using the default expiration for the primary and secondary caches
	cache.Set<List<ReportDetail>>(cacheKey, report, DateTimeOffset.Now.AddMinutes(20), "Default");
