.NET 4.0、4.5或4.6.1是否可以全部安装在一台计算机上? [英] Can .NET 4.0, 4.5 or 4.6.1 all be installed on one machine?

问题描述

所以我现在将项目从Win 7 4.0 vs 2010迁移到Windows 10 vs 2015.

So im now migrating the project from win 7 4.0 vs 2010 into windows 10, vs 2015..

推荐答案

嗨Appsw，

Hi Appsw,

感谢您在MSDN论坛中发帖.

Thank you for posting in MSDN forum.

.Net Framework 4.6已预先安装在Win 10中.请参考:

.Net Framework 4.6 is pre-installed within Win 10. please refer to:.NET Framework System Requirements.

您不需要单独安装4.6，直接转到控制面板" \程序" \程序和功能"即可启用V4.6功能:

You don't need to install 4.6 separately, directly go to Control Panel\Programs\Programs and Features to enable V4.6 feature:

启用此功能后，您将无法安装4.0和4.5，因为V4.6是Microsoft .NET Framework 4和4.5的高度兼容的就地更新.

Once this is enabled, you couldn't install 4.0 and 4.5, because V4.6 is a highly compatible, in-place update to the Microsoft .NET Framework 4 and 4.5.

>>> can 他们  共存?

>>can they coexist? or will there be any performance issues?

请参阅版本兼容.NET Framework   ;， .NET Framework 4.5及其发行版(4.5.1、4.5.2、4.6、4.6.1和4.6.2)与使用.NET Framework早期版本构建的应用程序向后兼容，因此通常在将项目迁移到 另一台机器.

Please see Version Compatibility in the .NET Framework , The .NET Framework 4.5 and its point releases (4.5.1, 4.5.2, 4.6, 4.6.1, and 4.6.2) are backward-compatible with apps that were built with earlier versions of the .NET Framework, so commonly there isn't any performance issue after migrating project to another machine.

>>我们还有其他缺点吗?

请不要担心，如果您发现v4.6中存在与v4.0和v4.5不兼容的任何类库，则可以重新调试并重新编译. style ="font-family:'Segoe UI'，sans-serif; font-size:10pt">

Please don't worry about it, If you find there is any class library in the v4.6 not compatibility with v4.0 and v4.5, you could re-debug and re-compile then.
