从.NET Framework 4.0升级到4.5

Question

I Have a solution with a lot of projects (WCFs, MVC 3, Console and Class Libraries). I retarget the .Net Framework in all projects from 4.0 to 4.5 and build all without errors.

Except for having to install .NET Framework 4.5 on the server, do I need to check or to be worried with something else?

Is the process of retargeting the .Net Framework simple at all?

Answer 1

根据我的经验，这很简单-但是有一些正式的重大更改 （这些更改从未影响过我的升级）

Answer 2

.Net 4.5 is an "in-place upgrade" to .NET 4.0 so there SHOULD be no problems.

I highlight the "should" as there are some rare cases where it can make problems, but only testing your application will tell you that.

Answer 3

如果从2.0或3.5等较旧版本进行升级，则您更有可能遇到问题。
