Hi,
I have an ASP.NET application. I want to use IsolatedStorage in this
application. When I run this application with anonymous access set in
IIS (user set to IUSR_<machine>) and impersonation set to false in
web.config, IsolatedStorage works fine.
But when I try to set impersonation to true via the web.config, calling

IsolatedStorageFile.GetUserStoreForDomain()

get me an IsolatedStorageException with this call stack:

System.IO.IsolatedStorage.IsolatedStorageFile.nGetRootDir(IsolatedStorageScope
scope) +0
System.IO.IsolatedStorage.IsolatedStorageFile.InitGlobalsNonRoaming(IsolatedStorageScope
scope) +42
System.IO.IsolatedStorage.IsolatedStorageFile.GetRootDir(IsolatedStorageScope
scope) +98
System.IO.IsolatedStorage.IsolatedStorageFile.GetGlobalFileIOPerm(IsolatedStorageScope
scope) +208
System.IO.IsolatedStorage.IsolatedStorageFile.Init(IsolatedStorageScope
scope) +37
System.IO.IsolatedStorage.IsolatedStorageFile.GetStore(IsolatedStorageScope
scope, Type domainEvidenceType, Type assemblyEvidenceType) +66
 
System.IO.IsolatedStorage.IsolatedStorageFile.GetUserStoreForDomain() +12

and tells me that storage directory cannot be created (System could not
find specified file).

Does anybody know what's wrong, or how to use IsolatedStorage with
impersonation in ASP.NET?
Thanks
