The process of translating RESX files is time consuming, so it is wise to study a good example before starting such a journey.
Paint.NET (driven by Rick Brewster) happens to have great (and complete!) translations serving as great )ample materia.
So below are steps that you can use to get started.
The process
Create good Base RESX files
The first step is to create good .RESX files for your base language. This alone is a tedious process in itself, as for all the strings (and potentially other resources) used in your application, you need to determine if they should be translated. If so, you should make a key for each one, put them in the appropriate .resx file, and access it. The MSDN documentation explains how.
Use version control and differencing/merging/syncing tools
When translating software, you not only have the history axis, but also a language axis. That combination makes it much harder to keep everything, so a good version control together with good differencing tools is very handy.
I’ve had good experience with Team Foundation Server, Subversion (SVN), Git, and Mercurial (Hg), but less good experience with StarTeam, Visual SourceSafe and Serena Dimensions.
Beyond Compare is my favourite tool of choice for comparing files and managing with differences, merges and syncs.
Translate the RESX files
This is the really hard part; many translation agencies are specialized in this, companies have complete teams working on it (for instance, the Microsoft Developer Devision did the Paint.NET translation for 4 years in their free time).
Often, it helps to generate Excel or Word documents from the RESX files, but often translation deportments or agencies can handle RESX files fine.
Usually, there is much more to do than just translating, you should look at the whole internationalization picture, for instance by reading Guy Smith Ferriers book on .NET internationalization.
Verify the RESX files are complete and valid using ResxCheck
A important requirement of translation is to make sure the translated resources are at least technically valid and complete.
Doing that by hand is a very tedious job. Luckiliy, Rick Brewster (yes the Paint.NET one) wrote a great Resx tool to do just that.
An example is below.
Compile the RESX files into .resource and assembly files
When your RESX files are ready to be tested, you need to generate .resource files from that and sometimes resource assemblies.
You can use ResGen to generate resource files, and the Assembly Linker to link the resource files into assemblies, or generate sattelite assemblies.
Using the resources
I won’t go into much detail here, as there are many ways to use the translated resources.
The tooling
There are many tools you can use, and the actual use highly depends on the size of your project, the number of translations, and how your process is organized.
I’ll point to a few tools that are interesting or that I have used.
The Bing Translation API
Now that the Google Translate API has been deprecated, the only online translation API is the Bing Translate API provided by the Bing Translator team. There are plenty of examples on how to do that from various environments. You need a Bing AppID in order to use this. And you can do “only” 50 translations per minute (each at a maximum of slightly less than 64 kilobyte).
Examples
I downloaded the Dutch 3.10 translations of Paint.NET because it includes an Excel document that is a good example of how to track progress or compare multiple translations.
Then I downloaded the Paint.NET 3.5.x original strings, and the Dutch 3.5.x translations and unpacked them in the C:\TEMP directory.
Finally, I ran the ResxCheck on them:
C:\temp\PaintDotNet.Strings.3.NL>ResxCheck.exe ..\Strings\Strings.resx PaintDotNet.Strings.3.NL.resx
ResxCheck v3.30.3033.25892

There were no errors
Hopefully this will save you some time, and me too when I’m working on another translation project.

PS: If you want the Paint.NET installer to be multi-lingual, follow these steps on the Paint.NET forum.
PS2: For the people wondering why the Dutch language is not called Nederlandisch or something similar, please read the Wikipedia articles on Names for the Dutch language and Netherlands (terminology).
