Gets the path for the application data that is shared among all users.
Returns
The path for the application data that is shared among all users.
Remarks
If a path does not exist, one is created in the following format: base_path\company_name\product_name\product_version
product_version first looks to see if the assembly containing the main executable has the AssemblyInformationalVersion attribute on it. If this attribute exists, it is used for both product_version and common_app_data_path. If this attribute does not exist, both properties use the version of the executable file instead.
The path will be different depending on whether the Windows Forms application is deployed using ClickOnce. ClickOnce applications are stored in a per-user application cache in the C:\Documents and Settings\username directory. For more information, see Accessing Local and Remote Data in ClickOnce Applications.
