Your Framework Version Number
You can specify your own Framework version number. It consists of four numbers, each of which must be in the range 1 to 9999999.
The version number is specified in the Primary Version . Secondary Version . Build Number . Revision Number format.
The version number is significant when using VLF.NET as it indicates to Internet Explorer that the version of your Framework has been updated on the web server.
