I was getting the error : The project type is not supported by this installation.

Running Devenv.exe/resetskippkgs helped..

Thanks a lot..

“We are working on an interactive Silverlight designer for Visual Studio – but it isn’t ready to ship just yet. Instead we have the Silverlight XAML source editor with design-time preview inside VS 2008 right now. In the future we’ll be enable the WYSIWYG interactiveness as well.

Hope this helps,

Being a bit of a newbie here I wasn’t aware that there is Beta 1 and now Beta 2 – with two versions of silverlight_chainer.exe out there – Beta 1 about 56Mb and Beta 2 about 86Mb.

So my problem came down to mismatched beta versions.

Beta 2 is now installed and creating Silverlight projects without the IVsSilverlightService error.

However when I try to draw something in the design area nothing happens – the + shaped mousepointer doesn’t draw a grid or a button or anything it’s supposed to on a new form.

It works in Expression Blend 2.5 June Preview, but that doesn’t seem to have a DataGrid component. So it looks as though I’m going to be doing a lot of hand coding (Property panel not supported in VS2008 Silverlight projects either).

Is that right or have I missed something?

If memory serves me right then the KB fix was part of the chainer and should not be installed before you install the chainer, maybe that caused the problem?

In the end I found the problem on my system after I extracted all the files from the chainer (about 4 or 5 of them I think) and started to install them one by one manualy.

I hope this is helpfull,

Actually what I did was
- uninstall all traces of Silverlight/SDK/Tools – all versions
- uninstall VS 2008 SP1 and all VS2008 patches and hotfixes, such as KB949325

This left a plain vanilla version of VS2008 behind.

Then I:

- Ran CCleaner and resolved all Reisgtry issues.
- Installed Silverlight 2.0.30226.2
- Installed Web Dev Hotfix KB946781
- Ran silverlight_chainer.exe
- Ran devenv.exe /resetskippkgs

All were sucessful, but when I came to start a new Silverlight project I got the IVsSilverlightService error.

I’m using XP with SP3 v3264 on an Inspiron 1721.

VS2008 is the default install – on drive C:

I haven’t removed anything from C:\windows\Installer

It’s a pretty plain vanilla install I’ve got here.

I can’t see any other tips and so I’ve run out of things to try.

Any help much appreciated!
