Obtains machine-scoped isolated storage corresponding to the application domain identity and the assembly identity.

Public Shared Function GetMachineStoreForDomain As IsolatedStorageFile
Dim returnValue As IsolatedStorageFile

| Exception | Condition |
|---|
| SecurityException | Sufficient isolated storage permissions have not been granted. |
| IsolatedStorageException | The store failed to open. -or- The assembly specified has insufficient permissions to create isolated stores. |
The same assembly code will use different isolated stores when used in the context of different applications.
GetUserStoreForDomain is functionally equivalent to the following code:
GetStore(IsolatedStorageScope.Machine Or IsolatedStorageScope.Assembly Or IsolatedStorageScope.Domain, Nothing, Nothing)
GetStore(IsolatedStorageScope.Assembly | IsolatedStorageScope.Domain | IsolatedStorageScope.Machine, null, null);
Different assemblies running within the same application domain always have distinct isolated stores.
The following code example demonstrates the GetUserStoreForDomain method. For the complete context of this example, see the IsolatedStorageFile overview.

isoFile = IsolatedStorageFile.GetUserStoreForDomain()
