Vritant Bhardwaj
Live Unit Testing is the automatic test running feature in Visual Studio Enterprise. As you make code changes, Live Unit Testing detects what tests are impacted and runs them in the background. This way you always know if the tests covering a certain line of code are passing or failing. You can see what your code coverage is for each line of ...

IntelliTest for .NET – Test More with Less (effort)

September 30, 2015 Sep 30, 2015 09/30/15
Visual Studio Blog
Writing a suit of unit tests that exhaustively exercise and validate the logic of the code under test is not easy. It can even be considered too expensive to do at all. Fortunately, the IntelliTest feature shipping in the Visual Studio 2015 Enterprise Edition addresses both concerns: it helps you achieve high code coverage at a fraction of the...

Visual Studio Blog
Starting with C# 3.0 and Visual Studio 2008, you can use expression trees to get information about objects, types, and members. In this post I’m going to show some examples and explain what benefits you can get by using this technique. If you are not familiar with expression trees, I would recommend reading Charlie Calvert’s blog post ...

Visual Studio Blog
First of all, let’s take a look at the example from one of my previous posts. It creates an expression tree for calculating the factorial of a number. ParameterExpression value = Expression.Parameter(typeof(int), "value"); ParameterExpression result = Expression.Parameter(typeof(int), "result"); LabelTarget label = Expression.Label(...

Dynamic in C# 4.0: Creating Wrappers with DynamicObject

October 19, 2009 Oct 19, 2009 10/19/09
Visual Studio Blog
In the previous post I showed how you can use the new dynamic feature and the ExpandoObject class to add and remove properties at run time, and how this can make your code more readable and flexible than code written with LINQ to XML syntax. But there were some obvious flaws in that example: While ExpandoObject provided better syntax, LINQ to...
