If you’re building Silverlight applications and need to be able to run Silverlight 2 and Silverlight 3 on the same machine (even though Visual Studio 2008 doesn’t support Silverlight multi-targeting) then check out Amy Dullard’s post. I won’t go through all of the steps since she outlines them nicely, but here’s an overview:
- Download a .bat file that Amy provides
- Download the Silverlight 2 Tools and install
- Download the Silverlight 3 Tools and install
- Run Amy’s Setup_SLTools_Util.bat file which will generated some “version switcher” .bat files (see screenshot)
- Click the appropriate .bat file to switch between Silverlight 2 and Silverlight 3 versions
I tried it out and it worked great on my box for Visual Studio 2008 SP1. I noticed that Silverlight 3 controls still show up in the Toolbox when in Silverlight 2 mode but that’s not a big deal. Files are also included to work with Web Developer Express although I didn’t try that out. It took less than a minute to make the switch between versions which I’m happy to deal with since it beats firing up a virtual machine or dual-booting. Awesome trick, so thank Amy by visiting her blog!
Note: Visual Studio 2010 will have Silverlight multi-targeting like we have now in Visual Studio 2008 for various applications.
