It’s a public holiday in the UK and the weather’s turned sour but playing with XAML and WPF can still bring on a smile – I’m not claiming it’s anything new or clever but I enjoyed it ( paste into Kaxaml or XamlPad to view );

it ends up producing a process list something like this;
and the UI is a bit horrible but I was just building an example of binding and found the whole “code-free” nature of that particular lump of XAML to be a very positive thing.
The other thing that made me smile today was thinking about how I can use Windows XP mode in Windows 7 in order to run up IE6 on an operating system that doesn’t have any .NET Framework installed and then I can show how the .NET Client Profile installation works.
That is, I spring up a virtualised IE6 on my Windows 7 desktop by just having a shortcut;
and it spins up the virtual environment;
and that spins up IE 6;
and I can then point that virtualised IE at my local machine where my “Hello World” ClickOnce application lives;
and it launches the setup process which launches the .NET Client Profile setup;
which runs the bootstrapper and then goes off to download the client profile itself and install it;
and once that is run up it launches my ClickOnce setup;
and runs my app;
( not that the app itself is worth running 🙂 ).
Having done this, I can just shut down the Virtual PC and remove the Undo Disk and I’m back to a nice state where I don’t have any .NET Framework installed on that virtualised XP and so I can start again. Nice – there’s something about the desktop integration here that makes it a lot more friendly (for me) than having to switch off into separate windows for the Virtual PC bits and I really like what they’ve done with Undo Disks here – for me it’s much nicer than being asked “Do you want to save/discard?” each time I shutdown the VPC.
Asides;
- I made a short screencast about the .NET Client Profile a while ago. It’s up here.
- I noticed (and watched) a video the other day about .NET Framework V4.0 and WPF features and there’s a discussion in there about how the .NET Client Profile becomes more applicable in .NET 4.0 so it might be worth taking a look at that video. It’s here.
