Fujiy Util NuGet Package

With this package you get data from cache or calling your method writing just one line of code.

Usually you do this(for ValueTypes, but Ref Types are similar):

decimal price;

var returnFromCache = Cache["CarClassGetPrice" + carId];

if(returnFromCache is decimal)
{
price = (decimal)returnFromCache;
}
else
{
price = GetPrice(carId);
Cache["CarClassGetPrice" + carId] = price;
}

With Fujiy.Util you just write:

decimal price = CacheHelper.FromCacheOrExecute(() => myObj.GetPrice(carId));.
