We are underway on a translation of the App-V Client book into German. With luck, “Das Microsoft App-V Client Buch” will be published by summertime.
Nico Lüdemann, a fellow MVP and CTP, is busy working on the translation. As App-V 4.6 SP1 did not change the client in any significant way (as far as we know!) we didn’t need to update the book. Like the English version (or should I say American?), it will be published on our store at Lulu so that you can print on demand your order and have it shipped right to your door.
PS: I noticed the 4.6 SP1 RDS client on MSDN and Technet this morning, not sure when it showed up.
