Which user account is IIS running under? I need to check if there's a reason it can't access isolated storage.

[tkarpinski]

I'm using the standard AppPool - ASP.NET v4.0 - (ApplicationPoolIdentity)

[andrewdavey]

Please try pulling the source for Cassette and changing line 21 of Cassette.Web\CassetteApplication.cs to:

IsolatedStorageFile.GetMachineStoreForAssembly()

I'm hoping the app pool account can access that location instead.

[tkarpinski]

I think that did the trick - the exception is gone. now I'll move onto using it.

[andrewdavey]

Thank you for testing that. I will try to get it into the source this week and update the nuget package.

Hi Andrew,
I ran into the same problem and fixed it in the same way.

Maybe it makes sense to allow this feature to be configurable through config section?

Thanks

[andrewdavey]

Cassette v0.5.3 uses GetMachineStoreForAssembly so should fix this issue. Can someone please verify. Thanks.

Just after updating to 0.5.3 and deploying (Windows 2008 R2 virtual maching, AppPoolIdentity user, .NET 4) i got some exception, but I believe it's related with my changes in Cassette. I had manually cleared isolated storage in my Users directory, and web site started working just fine.

Just for your info, that's exception which I got (but I still believe it's my problem, not your one):
'''Server Error in '/' Application.
Unable to delete file.

Sorry, it seems I forgot to push Cassette.Web 0.5.3. It's now there. Please update and try it again.

0.5.4 Still uses GetMachineStoreForDomain and I am getting this error in IISExpress.

Changing to GetMachineStoreForAssembly fixes the issue.

Am I missing something, or did you decide not to push this change?

[andrewdavey]

Erm, that's odd. Perhaps I messed up the nuget build...

I'm very close to releasing the big-rewrite of Cassette (big-rewrite branch for those who want a peak). It should have bugs like this squashed and lots of new features to play with. So I hope you don't mind waiting just a little longer :)

Fixed in 0.6
