Getting Started with Windows Phone 7

published 965 days, 12 hours, 12 minutes ago posted by

KodefuGuru 965 days, 19 hours, 6 minutes ago

Microsoft has a video series to help developers get started with Windows Phone 7. Here’s the first by Nancy Strickland. This video gets you set up with the developer tools and shows you how to build your first application. If you’re familiar with Visual Studio, it’s amazingly simple to build and debug WP7. If you haven’t seen it yet, the coolest thing in my opinion is the windows phone emulation. As explained in the video, the grab handles are slightly larger than the visuals because it represents the... (more)

Continuation-Passing Style Overload

published 1000 days, 5 hours, 28 minutes ago posted by

KodefuGuru 1001 days, 2 hours, 47 minutes ago

I wrote about continuation-passing style in a post a couple of months ago, and I’ve had time to ruminate over it since. One consideration I had is whether to return a type or not. This is easily handled by overloading the method. I also describe how I created an executable with Func (more)

Is That Closure or Inheritance?

published 1014 days, 5 hours, 3 minutes ago posted by

KodefuGuru 1015 days, 3 hours, 40 minutes ago

In response to my previous story, a commenter asked if the code I posted works due to a closure relationship rather than inheritance. The argument is that the field can be accessed by a nested class, and it wasn’t actually passed as a member to the other class. The reader of the story states that the field would still be accessed in Java even if Employee didn’t inherit from Person. Then, the question is asked if it’s different in C#. I’m not familiar enough with Java to speak about how it works, but I ... (more)

Are Private Members Inherited?

published 1015 days, 2 hours, 48 minutes ago posted by

KodefuGuru 1016 days, 3 hours, 57 minutes ago

On one level, it would appear that classes don’t inherit private members. Public and protected members are accessible by the subclass, but those pesky privates seemingly can’t be accessed. Of course, they’re there, otherwise calls to the exposed methods would not work. Then, there’s always reflection to access them. But I’m not really concerned about reflection or lower-level activities such as memory access; I’m more interested in the higher level concept of inheritance. Is the private member passed on ...

Remove Generic Parameter Refactoring

I’m a hardcore coder who is into design patterns and best practices. But sometimes, you just needs to crank out a simple little application for someone to manage a database of employees or orders… maybe both! Recently, some of use have turned to ASP.NET Dynamic Data for scaling websites, but websites aren’t always the best solution. What if your client really wants a desktop application with rich functionality like exporting to Excel? Introducing the next wave of application scaling: LightSwitch! (more)

Review: Visual Studio 2010 Ultimate Edition

posted by

KodefuGuru 1023 days, 14 hours, 52 minutes ago

Choosing the right edition of Visual Studio 2008 for your organization depends on your job role. This sounds like a simple process, but it’s complicated for IT pros who have multiple job roles. This is not an issue in Visual Studio 2010. In Visual Studio 2010’s simplified tier structure, each tier — aside from Test Professional (which is the only role-specific version left) — adds features to the previous tier. (Common components are discussed in my previous reviews of Visual Studio 2010.) In this arti... (more)

First Look at the Razor CSharp HTML File in MVC 3

published 1023 days, 4 hours, 48 minutes ago posted by

KodefuGuru 1024 days, 1 hour ago

The day before I left for IEEE ICCSIT 2010, there was a huge announcement about a new view engine for ASP.NET: Razor. It was old news by the time I returned, but I couldn’t help but sit down and play with it. I skimmed a few a blog postings on it, but I wasn’t getting anything good. So, I downloaded the ASP.NET MVC 3 Preview 1 and began playing with it myself. After installing the preview, I created a new ASP.NET MVC 3 Razor application. I then proceeded to open the Views/Home/Index.cshtml to see what i... (more)

Unpack and Transform Tuples with CPS

posted by

KodefuGuru 1028 days, 3 hours, 26 minutes ago

The tuple class made its debut in the .NET framework along with a language that supports it well: F#. But being a first-class citizen of the framework means other languages have access to this data type as well. Unfortunately, neither C# nor VB obtained any language support for tuples, and it ends up being treated as a dumb, generic data container instead of the powerful data class that is oftentimes found in functional languages. Accessing the elements of a tuple is rather bland, as each piece is named... (more)

Summation Functions

KodefuGuru 1030 days, 4 hours, 8 minutes ago

Creating a summation function in C# isn’t difficult in itself. After all, it is perfectly reasonable to create functions that consist of more than one line. What is interesting is abstracting it so that any function can become a summation function. (more)

Call a Function to Infinity

published 1030 days, 7 hours, 15 minutes ago posted by

KodefuGuru 1031 days, 2 hours, 56 minutes ago

What if the resulting value of a function was used to feed the parameter of the same function? It easy enough to call a function, get its result, then pass it back in. However, I wanted to abstract this and make it work for anything whose generic parameter type is the same as the generic result type. If it’s abstracted, there must be some arbitrary end point… right? How about infinity? (more)

Maybe as an Extension Method

published 1053 days, 2 hours, 31 minutes ago posted by

KodefuGuru 1056 days, 3 hours, 1 minute ago

A frequent question I received concerning the Maybe static class was “why didn’t you make extension methods?” I am a proponent of extension methods, so it would seem that I would prefer “42”.ToInt32() over Maybe.ToInt32(“42”). However, I immediately created a static class for this despite my previous criticisms of helper classes. Why? Semantics What does it mean when someone writes Request.QueryString[“index”].ToInt32()? It’s not obvious that ToInt32() returns a Nullable (more)

TryParse vs Convert

published 1061 days, 5 hours, 11 minutes ago posted by

KodefuGuru 1063 days, 5 hours, 5 minutes ago

Since I’ve been coming out against out params, I sometimes get asked about the TryParse pattern. My typical response is that the most egregious offenses of out param usage occur when there is more than one, but even one should be avoided. However, I was recently presented with a more specific question: “lets say you had to pick up a query string param in WebForms/ASP.NET and make it an Int32... would use Convert or TryParse?” This is a very practical question, and given the choices it is interesting to e...

C# Ninjitsu

C# is no longer a purely object-oriented language. It is no longer just an imperative, class-based, component oriented discipline. It is also a generic, declarative, functional discipline. I will introduce new principles in the context of the classic object-oriented and SOLID principles and show you how to master the C# language to be more declarative, more fluent, and more functionally cohesive.
