GERMAN: WCF Einführung (WCF Introduction)

On 10, Nov 2010 | inGeneral | vonJohannes Hoppe

[ENGLISH] I found this presentation on my disk. It’s an introduction to the Windows Communication Foundation (WCF) that was released with .NET 3.0. The slides are in German only. But the demo solution is written in English.

@My Students: this is just for your interest! But I’m going to introduce Message Exchange patterns in the next lesson.

[DEUTSCH] Ich habe diese Präsentation auf meiner Festplatte entdeckt. Sie führt in die Windows Communication Foundation (WCF) ein, welche ab .NET 3.0 mit an Bord ist. Die Folien sind auf Deutsch. Mit dabei ist ein Demo-Anwendung.

Lesson 05 – First ASP.NET MVC project (2nd part – Unit testing)

On 02, Nov 2010 | inRIA lecture | vonJohannes Hoppe

[BOX_START]Please repeat the stuff and answer the following questions by mail:
1. What are Unit Tests?
2. Why and when should I use them?
3. How do I write Unit Tests?

We will continue with the 5th lesson at Wednesday, the 10th of November 2010.[BOX_STOP]

In this lesson I want to finish the sample solution. For me a programming task is only finished, if all necessary Unit Tests are written and if those tests finish successfully!

Please make sure, that you have the latest version of

on your laptop. (checkout with TortoiseSVN!)

Windows Phone 7 Camp

On 31, Okt 2010 | inWP7 | vonJohannes Hoppe

This weekend I’m participating at the Windows 7 Phone Camp from Microsoft. Developing with Silverlight 3 is fairly straightforward! At the camp I wrote this small app:


HitTheRoad.xap

You can play the XAP file with the help of the “Application Deployment” tool from the Windows Phone Developer Tools. Let’s see if it will be accepted for the marketplace hub. :-)

By the way, I got a nice confirmation of participation:

Walkthrough: ADO.NET Unit Testable Repository Generator

On 27, Okt 2010 | inClean Code Developer | vonJohannes Hoppe

This walkthrough is going to show you the usage of my new T4 template called „ADO.NET Unit Testable Repository Generator“.

Table of contents:

My demo implements a small repository to manage simple text-snippeds in the database. I will start with an empty ASP.NET MVC 2 project. Any other type would work, too.

ADO.NET Unit Testable Repository Generator

On 26, Okt 2010 | inClean Code Developer | vonJohannes Hoppe

At work we are going to do a big refactoring on a ASP.NET MVC project. I learned a lot of this project. One hard lesson was: the code base is as good is the guidance of the senior coders. If you know the power of the Entity Framework, then you also know the countless possibilities to write wicked code. But I’m present at the office only for days a week. That’s why I’m planning to write some articles in the next time.

Lesson 04 – First ASP.NET MVC project

On 26, Okt 2010 | inRIA lecture | vonJohannes Hoppe

Hello Students,

tomorrow we will do some live coding. You should watch the NerdDinner video, if you haven’t done that already.
This time, no special preparation is required.

Please make sure that:

  • Visual Studio 2010 is running
  • MSSQL is running, too
  • you have ASP.NET MVC 2 on your machine (use the Web Platform Installer)

Update:
Download the codes from http://code.google.com/p/lecture-hoppe/ .

Lesson 03 – Hello ASP.NET MVC

On 20, Okt 2010 | inRIA lecture | vonJohannes Hoppe

In this lesson I want to concentrate on the server side of our application. As you already know, web applications are a very big topic. This time you will not need a lot of preparation, if you are already familiar with a scripting language like PHP or even a web application framework like Ruby On Rails.

But it is generally a very good idea to get in contact with ASP.NET MVC now! I can recommend the famous reference implementation “NerdDinner”.

In the next time am going speak about a lot about stuff that can be found in NerdDinner, too. So the following video is worth watching it:

Your course achievement

On 12, Okt 2010 | inRIA lecture | vonJohannes Hoppe

I thought a lot of the practical part of my course. As you already know, I want you to develop a small but functional rich internet application. You asked me to use server and client-side programming language of your choice.

Generally it is great idea to have diversity. But in our case a free choice could have drawbacks:

  • skilled programmers probably don’t learn something new
  • you could reuse an existing software, which would be unfair to the other students
  • I cannot help you

So my specification for you application is as following:

Lesson 02 – Hello SketchFlow

On 12, Okt 2010 | inRIA lecture | vonJohannes Hoppe

Last week my lecture contained only boring PowerPoint slides. As compensation we are now going to be creative!

In most cases developers and customers speak a completely equal language.* Every party has a clear vision of the software in mind. It is so clear, that even a boring requirement specification is completely unnecessary. Don’t waste time, start coding! NOT! ;-)

But luck is on our side. We have a lot of free and cool tools that save us a lot of pain. One of them is Microsoft Blend 4 with SketchFlow. (SketchFlow is only available in the Ultimate Edition!) Basically I will teach you exactly the same as the smart guy in the following video:

Book recommendations

On 10, Okt 2010 | inRIA lecture | vonJohannes Hoppe

Some students asked me for some good books that I would recommend.
The module description (Modulbeschreibung) of the lecture lists some skills, which are all required and obligate:

  • General knowledge in programming
  • General knowledge in computer networks
  • HTML / CSS / JavaScript

For these skills I would recommend the followings books / resources.

German:
