public class Framework { public static int SomeCalculatedValue; static Framework() { // Lot of complicated code could be here to calculate // the value of SomeCalulatedValue but, for simplicity: SomeCalculatedValue = 5; } }The constructor code will only fire when the first instance is instantiated. All subequent instantiations (as you would be doing in, for example, Page_Init) would not run the constructor code and would share the SomeCalculatedValue. E.g:
Framework f1 = new Framework(); // f1.SomeCalculatedValue set to 5 Framework f2 = new Framework(); // Constructor code not run but SomeCalculatedValue = 5; f1.SomeCalculatedValue = 6; // Now *all* Framework objects .SomeCalculatedValue will be 6 as well
