Generics (RSS)
Both VB and C# have a feature of generic overload resolution that is fairly helpful and yet a source of gotchas. Lets say you have two methods with the same number of arguments. One method has arguments with generic types and the other does not. For Example:

Really this guideline is a bit longer but putting it all in a blog title seemed a bit too much. The full guideline should read: "If a generic class constructor arguments contain types of all generic parameters, provide a static method named

Previously we discussed the opposite problem. This is a lesser but often more frustrating problem because there is no, AFAIK, built in solution for the BCL. However it's problem that can be solved once and reused with a generic solution. IComparable<T>

There are only a few missing features from our tuple implementation. Mainly FxCop compliance, debugging support and test case code. The actual functional work is complete. The one issue with FxCop compliance is the chosen names.

Part 5 produced equality tests for Tuples. This section will add comparison support through the IComparable<T> interface. Implementing comparable is very similar to adding equality support. Once again there is a generic class available to make all

Part 4 left us with a reusable, abstract and inference friendly Tuple class. The next step is to be able to test for Tuple equality. For the Tuple implementation, two tuples will be defined as equal if all of their members are equal.

One of the limitations of C# type inference is that you cannot use it to infer the type of a lambda expression. For example, the following code will not compile var f = () => 4; Normally this is not too much of an issue because you can just explicitly

Quick follow up to my earlier post . Fixing this issue in C# is even easier because of the existence of iterators. public static IEnumerable < object > Shim(System.Collections. IEnumerable enumerable) { foreach ( var cur in enumerable) { yield return

Quite awhile back I posted about how to create a re-usable singleton pattern in .Net. Link is here . A bit of time has passed and I've altered the pattern a bit. The reasons for the change are some new type inference patterns and FxCop cleanliness. The
