There is no shorthand for Visual Studio 2008 or prior for VB.NET. In Visual Studio 2010 and beyond, you can use the following shorthand: Public Property FirstName as String This will be handled as your short version in C# is – I think they call it “Auto Property” See also: Auto-Implemented Properties (Visual Basic)
The purpose of interning things is to be able to compare them by comparing their memory address; you ensure that you never create two objects with the same value (when the program requests the creation of a second object with the same value as an existing object, it instead receives a reference to the pre-existing … Read more

In addition to the other answers, the maximum identifier length that is accepted by the Microsoft Visual C# compiler is 511 characters. This can be tested with the following code: class Program { private static void Main(string[] args) { int aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa = 5; } } The length of the variable name there is 511 characters. … Read more
The answer is yes, but the solution is a little tricky. The System.Reflection.Emit namespace defines types that allows assemblies to be generated dynamically. They also allow the generated assemblies to be defined incrementally. In other words it is possible to add types to the dynamic assembly, execute the generated code, and then latter add more … Read more
Unicode escape sequences allow you to store and transmit your source code in pure ASCII and still use the entire range of Unicode characters. This has two advantages: No risk of non-ASCII characters getting broken by tools that can’t handle them. This was a real concern back in the early 1990s when Java was designed. … Read more
Python has such an operator: variable = something if condition else something_else Alternatively, although not recommended (see karadoc’s comment): variable = (condition and something) or something_else
I’ve just read this article from the MSDN Magazine: Building Tuple Here are excerpts: The upcoming 4.0 release of Microsoft .NET Framework introduces a new type called System.Tuple. System.Tuple is a fixed-size collection of heterogeneously typed data. Like an array, a tuple has a fixed size that can’t be changed once it … Read more
It turns out that SQL can be Turing Complete even without a true ‘scripting’ extension such as PL/SQL or PSM (which are designed to be true programming languages, so that’s kinda cheating). In this set of slides Andrew Gierth proves that with CTE and Windowing SQL is Turing Complete, by constructing a cyclic tag system, … Read more
It won’t work this way. You can just skip the explanation and see the code below 🙂 As you know ?. operator will return null if a child member is null. But what happens if we try to get a non-nullable member, like the Any() method, that returns bool? The answer is that the compiler … Read more
