NGem is a small utility that can help you to resolve assembly references (third-party or you own framework stuff).

This is the second post on how to work with NGem.

Lets assume you create a new project and start with creating its directory:

In the new project directory you can now run NGem to resolve the latest versions of the assemblies that you like to reference from a http reachable location. To set the location of the repository where the ngems are stored just edit the config files appsetting called nGemSource.

            

              
              <?
              xml
version="1.0"
              ?>
              
              
              <
              configuration
              >
              
              
              <
              appSettings
              >
              
              
              <
              add 
              key
              ="nGemSource"
               value
              ="http://ngem.devplex.net/gems"
              />
              
              
              </
              appSettings
              >
              
              
              </
              configuration 
            
          

Now type:

NGEM.exe install {your_package_name}

To see how you can create a ngem package take a look at the post here.

Because I’ve choosen to download my ngems from a password protected location (Windows Authentication and SSL + Basic Authentication are supported) NGem asks me for a username and a password (these will be stored – currently unencrypted – under your user profile directory (protected by the systems ACLs) is a settings file.

NGem will take care of adding the package plus all of its references to a directory called lib:

That’s it folks. I really think its easy this way coping with references.

Whats next? A build task? A Visual Studio Plug-In? Let me and Philip Proplesch know!

NGem is a small utility that can help you to resolve assembly references (third-party or you own framework stuff).

This is the first post on how to work with NGem.

So lets imagine you have created a few assemblies:

The assembly in the directory ObjectModel.Data relies on the one called ObjectModel. So we need to create a reference…

Its pretty straight forward. Just create a file in the corresponding directory called References.xml with the following content:

            

              
              <?
              xml
version="1.0"
              ?>
              
              
              <
              references
              >
              
              
              <
              add 
              name
              ="devcoach.ObjectModel"
              
              
              />
              
              
              </
              references
              >
            
          

Now lets build the ngems:

ngem.exe make “D:\lib\“ devcoach ObjectModel

ngem.exe make “D:\lib\“ devcoach ObjectModel.Data

Now just upload the ngems to a http reachable destination and you’re done.

I was really enthusiastic about Nu as I first read about it. But the problem for a lot of customers and also for myself is that it cannot cope with private assemblies – stuff that is not open source.

Today I started a new open source project with Philip – NGem: A gem like 3rdPartyAssembly resolver and packer with support for private gem repositories.

You can find the source code at github.

Heute hatten wir unser erstes .NET Coding Dojo. Auch wenn Ilker es nicht zu uns geschafft hat, war es ein voller Erfolg und hat allen Teilnehmern viel Spass gemacht.

Hier das Slide: http://www.lennybacon.com/download/Events/2010/2010-08-NET-Coding-DoJo.pdf

Und der Code von Philip: http://github.com/philipproplesch/NetugNiederrhein/tree/master/src/2010-08/FizzBuzz/

Last week I did talks on ASP.NET MVC and ASP.NET Controls at the .NET Developer Group Braunschweig and Dotnet User Group Dortmund. This way I’d like to thank Lars Keller and Paul Mitzel as well as all attendees for joining and havig such a great time!

Slides will be up on the user group pages soon as I submitted them today to Paul and Lars.

I’m proud to announce our first open source project released on GitHub.

The Docx2UnitTest Code Generator is based on an idea of Thomas Bandt. You can read his blog post here.

Philip Proplesch started out with a T4 template (of course edited with Tim Fischer’s fabulous tangible T4 Editor). After he told me about it I had the idea of doing it with a code generator (Visual Studio custom tool). The advantage is that you do not need to copy the T4 files around.

Spend the last few nights pair coding (thanks to my girlfriend for the time to build this amazing stuff!!!)…

Docx2UnitTest
A Visual Studio 2010 custom tool to generate unit tests from Microsoft® Word® 2007/2010 documents.

Supported frameworks are:
- MsTest
- NUnit
- XUnit

Features:
- It keeps the implementation of tests during re-generation.
- It keeps test methods attributes

Just add a *.docx file to a project in Visual Studio. The test classes will be generated immediately.

So give it a try and give us some feedback – I bet the regex to keep the existing code can be improved :-)

Btw: The colorful things in my IDE are TestLint from Typemock and ReSharper from JetBrains.

Get it here on GitHub…

Even redirecting the version by config doesn’t work:

      <assemblyIdentity name="System.Runtime.Serialization" publicKeyToken="b77a5c561934e089" />
      <bindingRedirect oldVersion="2.0.5.0" newVersion="4.0.30319.1" />
    </dependentAssembly>
  </assemblyBinding>
</runtime>

Grrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrr
