Oh No! i’ve just installed the .Net3.5 SP1 Beta + the VS2008 SP1 Beta, and it’s completely hosed my setup 🙁
When I open VS2008 and try to open a project, when the XAML/WPF view opens, i get the dreaded designer error window, with an exception i’ve not seen before 🙁
Loading this assembly would produce a different grant set from other instances. (Exception from HRESULT: 0x80131401)
Unfortunately the only reference I can see for this regarding the 3.5SP1 beta is in the comments on ScottGU’s blog, and the response is "send me an email" . Thing is none of the possibles apply to me. I’m on Vista SP1, didn’t install the Silverlight betas, or anything else to do with Silverlight, nor did I install the update.
I’m just re-installing VS2008 now as nothing else seems to work.
In short, beware!
🙁

Did you find a solution? Looks like I’m in the same situation.
Hi Chris,
Yes I did managed to fix devstudio, (the next post on my blog detailed this)

you didn’t read far enough 😉
Basically there are 2 updates that are available via windows update that aren’t installed by default (see post), but installing those fixed the issue for me!
Thanks for reading!
Hey Rob,
I just ran into exactly the same problem as you did. I poked around (and found the same comments on ScottGu’s blog) but nothing I tried helped. I detailed my experience here:

In the end, it turned out that a bad addin, StudioTools, was the culprit. Out of curiosity, did you have that addin installed?
Hi Matt,
No, I didn’t have that add-in installed. I notice that there were comments about having resharper though,but in the end that wasnt my problem either. Seemed that good old windows update solved my problems anyway.
Cheers
Rob
