Expiration date NET 4 Beta 1

I have 25 days left to use VS2010 Beta 1. Will I still be able to use an application made in this version after that or is there an expiration date of the framwork itself? And yes I am upgrading but for differ开发者_运维问答ent reasons I need to use this application a couple of months more. Anyone knows?

The application needs to run in Beta 1 IE I can not upgrade it until after a couple of months.

Applications built with the beta version of .NET 4 and Visual Studio 2010 will continue to work with the release versions.

The answer is yes it works fine to run the application after the expiration date and even to run VS Beta if you just set the time back :) This has to be done before the expiration though!
