I hope I didn’t say “I am a doughnut.” For native German speakers, you may already know about Lars Keller, a recent recipient of the Visual Studio MVP Award. When the localized Help files and documentation aren’t enough, it helps to read technical content in your own language. Lars writes a developer blog with quite a few Office development entries:
All about .NET, VSTS, VSTO and more
Lars also co-founded an aggregation of many German language blogs and event announcements about Visual Studio Tools for Office:
Alles zum Thema Visual Studio Tools for Office
You can find more non-English content written and aggregated by two other VSTO MVPs, Ryosuke Uemoto and Pablo Pelaez Aller. You can find a Japanese blog on VSTO, a Japanese blog on VSTO and other Developer topics, and a Spanish blog on VSTO.
If you know of other non-English web sites with great Office development content, then please leave a comment.
