Drag-copying in Visual Studio Solution Explorer.

NOTE: I've tried this in Visual Studio 2008 (VS2k8), I'm assuming the same thing happens in Visual Studio 2005 (VS2k5). In the process of refactoring, it's *very* common for me to rename a type. This is most easily done by renaming the file...

Nested Types

Recently Michael Features blogged about nested types . The title was almost "nested types considered harmful". I don't agree. I don't agree that they're any more harmful than any other C# construct (except goto...). Nested types...

Comparing CodeRush Refactor! Pro and Resharper 4, part 1 or N -- first glance.

Metadata view of code in referenced assemblies This is a big one for me. For whatever reason, Refactor 4 (and prior) completely disables this and sends you to the Object Browser instead. You get metadata view with CodeRush Refactor! Pro. Keyboard layout...

Entity Framework Petition of Vote of Non Confidence

I had intended to be happy simply being a signatory of ADO .NET Entity Framework Vote of No Confidence. But, there's people suggesting signatories of this petition are wackos or on the fringe. Do yourself a favour and read the petition . Read what...

Fundamentals of OOD Part 3: Method Cohesion

Single Responsibility Principle (SRP) helps us write more cohesive types and methods. Cohesion is the relatedness of the members of a type to each other and the relatedness parts of a method's code to other parts. Method cohesion Often times a method...

Fundamentals of OOD, Part 2 - Encapsulation Scope

Let's look at the ubiquitous Person concept. It might seem logical that an application that deals with people should have a Person interface for classes to implement. For example: public interface IPerson { String GivenName { get; set; } String SurName...

Fundamentals of Object-Oriented Design (OOD) Part 1

With increased usage of patterns and situationally specific strategies, people sometimes lose sight of the concepts and principles behind these patterns and strategies and fail to follow them when they're not using patterns or strategies. I feel it's...

Overcoming problems with MethodInfo.Invoke of methods with by-reference value type arguments

I ran into an interesting problem on the Forums recently. Basically, when you use MethodInfo.Invoke to invoke a method with by-reference value type arguments you can't have the invoked method update a variable/argument. The problem is, when you invoke...

Single-Entry, Single-Exit, Should It Still Be Applicable In Object-oriented Languages?

Before the modern high-level languages Edsger Dijkstra came up with "Structured Programming". This programming methodology relied on the programmer to form and enforce most of the structure of the program--manually keeping sub-structures and...

Testing the Units

In OO there's levels of abstraction. A class, for example, abstracts a read-world concept into a encapsulated bit of code. A class is autonomous. That class lives in world with other classes and interacts with them, but is autonomous. I believe development...

A Time and Place for Code Comments

I've dealt with more than one person who believes all code comments are bad. The first person I encountered who said that also asked me to explain why a particular algorithm was used instead of another because there were no comments explaining it...

Dependency Injection

Dependency injection (DI) is a form of inversion of control. There seems to be a tendency in some circles to refer to dependency injection as inversion of control (IoC). Dependency injection is a form of abstraction by removing physical dependencies between...

My Visual Studio 2008 Code Analysis Rules

Although a couple of suggestion for changes to existing rules seem to have made it into Visual Studio 2008 Beta 2, unfortunately, none of my suggestions for new Code Analysis rules made it into Orcas Beta 2 (and thus likely not in RTM). I was holding...

Exception Logging

There is often a requirement for an application to log unhandled (and sometimes "handled") exceptions. This logging could occur to a log file, to the Event Log, a logging server, etc. There's great reasons to log exceptions but logging exceptions...
