Installing Silverlight Tools RC0 Without English Visual Studio
The release candidate for Silverlight Tools for Visual Studio is currently available for the English version of Visual Studio only. Users of non-English Visual Studio can still use this Silverlight Tools release candidate if they install the English version of Visual Web Developer Express with SP1 which is a FREE download.
Note, that installing Silverlight Tools RC0 on a machine with VWD Express SP1 ENU and VS 2008 SP1 non-ENU will allow Silverlight 2 development on VWD Express SP1 ENU only. Neither Silverlight 2 Beta 2 nor Silverlight 2 RC development will be possible on VS2008 SP1 non-ENU until the final version of Silverlight Tools is released for the language specific Visual Studio version installed.
