解决方案

  

如何方便的升级路径？是否升级到EF 5要求任何code变更或其他工作？

您将不得不升级到.NET 4.5的大多数新功能的工作。

  

是否有相关的任何新功能code-首先，这将是值得升级的呢？

不完全涉及到code-首先是因为它的横切，但还是值得一提：支持ENUM

My application is based on .NET 4.0 and EF 4. I'm now looking at upgrading to the latest versions.

• Are there any breaking changes or behavioral differences that may adversely affect my application?
• How easy is the upgrade path? Does upgrading to EF 5 require any code changes or other work?
• Are there any new features related to code-first that would be worth upgrading for?

解决方案

How easy is the upgrade path? Does upgrading to EF 5 require any code changes or other work?

You'll have to upgrade to .net 4.5 for most new features to work.

Are there any new features related to code-first that would be worth upgrading for?

Not exactly related to code-first, because it's crosscutting, but still worth mentioning: Enum support.
