These are fairly straight forward samples. LineSample.Run() We start a stop […]

Part One: Starting with MVVMPart Two: The MVVM solution structure and basic frameworkPart Three: Base ClassesPart 4: Sampler View, View Model and Model Finally, before getting in the actual TPL samples there is one last thing to cover. How do we run the samples? Well, as previously discussed the Submit button in SamplerView is bound […]

Part One: Starting with MVVMPart Two: The MVVM solution structure and basic frameworkPart Three: Base Classes I want to go over the main view (SamplerView), view model (SamplerViewModel) and model (Sampler) classes next. I’ve gone over the ItemsControl that populates the TPL samples but I wanted to cover the other MVVM aspects as well as […]

Part One: Starting with MVVMPart Two: The MVVM solution structure and basic framework Let’s take a look at SampleView, SampleViewModel and the base Sample class all of our models extend from so we can get a better understanding of how this works. In the first set of samples included with the code the only controls […]

In the previous post I wrote a brief intro to MVVM along with some pros and cons. Next up in this series is an explanation of the layout of the solution and some of the rudimentary framework. Don’t forget you can download all the code here. In the image above you can see the layout […]

About a year ago I did a session here at work going over the Task Parallel Library (TPL), it’s benefits and where it works and doesn’t work. To illustrate a lot of the TPL I wrote a simple WPF application with standard code-behind that contained a ton of code samples that demonstrated the concepts I […]

Next up is a few fun facts with strings. My software development path went from C/C++ -> Java -> C#. While in Java strings always felt awkward. It felt strange to have to use .charAt to iterate over a char array. It also felt odd to have to use .equals on a string. I know […]

I want to start this post by defining what a reference type is and what a value type is. We’ll start with reference types. These are all objects that are not value types, pretty easy, huh? 🙂 So what are value types? Per the documentation they are numeric types (like int, decimal, float and other […]

There are a lot of threading issues that are fairly obvious which careful and conservative use of locks will solve. Conservative use is import because if we use locks too liberally we run the risk of turning all the work we’ve done to multi-thread back into a single thread scenario. The subtle issues are the […]

Custom event handlers should always follow this pattern: All I’ve done that is special here is declared the event handler with an empty delegate. This provides two advantages (the big one being the second). As a clearer, more complete example imagine we have the following code: but just by modifying the event declaration to: you […]
