Title
Body
Is there any calculation engine for C# that can automatically recalculate dependent fields when a value changes? Let me freestyle for a second, I'm imagining something like this.. Field<double> quantity = Field.Create<double>("Quantity"); Field<double> unitCost = Field.Create<double>("Unit Cost"); Field<double> total = Field.Create<double>("Total"); total.Calculation((q,uc) => q * uc, quantity, value); // would have signature something like this: // void Calculation<TR,T1,T1>(Func<TR,T1,T2>, Field<T1>, Field<T2>) This would set up fields that auto-propagate dependent values. quantity.Value = 5.0; unitCost.Value = 1.5; Assert.That(total.Value, Is.EqualTo(7.5)); Obviously this is a simple example, the end uses would be much more akin to the calculations of a complex spreadsheet. Thinking further it would be amazing if the field/cells would support change notification.
