To collect performance data from remote servers, when running a load test for example, use the following PowerShell script: clear$testId = "doodle"$durationSeconds = 20$threadsPerAgent = 5$client = ""$counterList = @( ".NET CLR Exceptions()# of Exceps Thrown / sec", ".NET CLR Memory()# Total committed Bytes", "\ASP.NET\Application Restarts", "\ASP.NET\Request Wait Time", "\ASP.NET\Requests Queued", "\ASP.NET Applications()\Requests/Sec", "\Web Service()\Current...

The Art Of Unit Testing, TDD

My quote-of-the-day, regarding Test Driven Development: I am convinced that it [TDD] can work to your benefit, but it’s not without a price (time to learn, time to implement, and more).

Data-binding Radio Buttons in Silverlight to Enum

In Silverlight there is no Enum.Getvalue() method, so there is not out-of-the box way of databinding a radio buttongroup to an enumerable value in a viewmodel. Step forward converters. using System;using System.Windows.Data;namespace YourNamespace{ public class EnumBoolConverter : IValueConverter{ #region Methods public object Convert(object value, Type targetType, object parameter, System.Globalization.CultureInfo culture){ if (value == null ||...
