    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
