Silverlight 5 向后兼容性

Question

我有一个用 4.0 版开发的 Silverlight 应用程序。我尝试使用 Silverlight 5 客户端运行它，到目前为止一切似乎都很好。

但我想知道；如果我的用户为客户端安装 Silverlight 5，确定我的应用程序仍能正常运行吗？我是否必须再次运行所有测试用例？

如果有人注意到版本之间的某些内容已损坏，请在此处列出! :)

谢谢

目前互联网上几乎没有证据，除了微软发布的证据，可以找到here和 here ，其中指出，总结:

Several changes have been made to the Silverlight runtime and the Silverlight Tools between Silverlight 4 and Silverlight 5. For these changes, the following principles apply:

• Most Silverlight 4 applications will work with Silverlight 5 without any changes.

• When breaking changes are required, Silverlight will try to maintain support for the old behavior, as well as the new behavior, by using a quirks mode.

Nevertheless, some changes made to Silverlight components can potentially cause your older Silverlight-based applications to fail (compile time, XAML load time, or possibly design time) or to behave differently.

和，

There are no known breaking changes between Silverlight 4 and Silverlight 5 in the Silverlight core runtime. Applications that were originally compiled using Silverlight 4 tools, and that continue to target the Silverlight 4 runtime, should work without issues on a client that has the Silverlight 5 runtime.

If your project references any Silverlight SDK client assemblies [...] make sure that your project specifically references the Silverlight 5 version of the SDK client assemblies [...]. A project that targets Silverlight 5 cannot use the Silverlight 4 SDK assemblies.
