So I’m a couple of weeks behind the times but the final silverlight 4 tools were released, so it was time to give it a spin.
The result is http://www.themissingdocs.net/LoopDeLoop.html
Its a cut-down version of my win forms LoopDeLoop, but it also has a couple of features the old one didn’t – like click-drag to apply changes to multiple locations, and proper fix position support (ctrl-F/ctrl-R/ctrl-U).
Silverlight 4 is noticeably better than Silverlight 2, but the errors on the designer when your custom controls fail in design mode, are a bit cryptic. It also took me a while to work out my ellipses were not showing because I hadn’t measured them during the measure phase.
I haven’t made any serious changes to my actual game engine, other than having to replace SortedDictionary with something else. (I reimplemented my approximatepointset using a dictionary an equality comparer which used fmod to round values, not quite as correct but it seems to still work well enough.)
It was interesting to see that attempting to manually capture a stacktrace (which happens just fine when you throw an exception) throws a security exception. Also Debug.WriteLine caused me some grief, had to remove those.
Also it might be my imagination, but it seems like the silverlight runtime is noticeably slower than the normal .Net runtime. And the fact that ctrl-f5 on a page containing a silverlight object doesn’t cause cache-invalidation of the silverlight object itself is quite annoying.
