“软件保障”是针对“企业”和“精选”批量许可持有者的 Microsoft 计划，它允许您在软件保障合同（通常为 2 年）结束之前获得软件的免费升级。但是，除非您所在的公司购买了大量 Microsoft 软件并且已经与他们签订了批量协议，否则您将无法获得软件保障。
我不知道有任何其他程序可以让您免费升级到下一个版本。 Visual Studio 2010 预计将在几个月后发布——您能等到那时再购买吗？
"Software Assurance" is a Microsoft program for "Enterprise" and "Select" volume licensees, and it allows you to get free upgrades for the software until the end of the Software Assurance contract (which is usually 2 years). But unless you are at a company that purchases lots of Microsoft software and already has a Volume Agreement with them, you will not be able to get the Software Assurance.
I don't know of any other program that allows you to get free upgrades for the next version. Visual Studio 2010 is expected to be released in a couple months--can you wait until then for your purchase?
Sounds too good to be true... but look at WebSpark from Microsoft if you are an independent developer. Free MSDN for 3 years if you meet certain criteria.

如果我是你，我会等到 VS2010 发布（2010 年 3 月 22 日）再购买任何东西。
您可以使用 VS2010 beta 2 来启动并运行直到那时。
该测试版甚至包括 “上线”许可证，以便您可以立即部署您的产品（如果您真的绝望的话）。
If I were you I'd wait until VS2010 is released (March 22 2010) before I bought anything.
You can use the VS2010 beta 2 to get things up and running until then.
The beta even includes a "go-live" license so you can deploy your product immediately, if you're really desperate.
听起来好得令人难以置信...但是，如果您是 Microsoft 的 WebSpark，请查看独立开发商。如果您满足特定条件，可免费使用 MSDN 3 年。
对于企业，请尝试 BizSpark。

For businesses try BizSpark.
当然试用期为 90 天（如果您还没有） 2008 年已经进行了试用。但到那时 VS2010 还不会完全推出，但很高兴知道这一点。
And of course trials are for 90 days if you haven't already trialed out 2008. But VS2010 won't quite be out by then, but its good to know.
