程序集版本匹配如何完全起作用? [英] How the assembly version matching works exactly?

问题描述

假设我在GAC中具有版本为1.1.1.5、1.1.5.1、1.1.6.2、1.2.1.1和2.1.2.1的程序集.我的应用程序有一个1.1.3.0版本的参考.哪个程序集将在运行时匹配?以及装配匹配的实际规则是什么?

Let's say I have assemblies in GAC with versions, 1.1.1.5, 1.1.5.1, 1.1.6.2, 1.2.1.1 and 2.1.2.1. My application have a reference of 1.1.3.0 version. Which assembly will be matched at runtime? and what are the actual rules for assembly matching?

推荐答案

如果您的引用需要特定的版本，则默认情况下，它将在程序集加载时失败，因为该版本不存在.

If your reference requires a specific version, by default, it will fail on assembly load, as that version doesn't exist.

但是，可以通过组装绑定重定向对其进行配置.这里会发生多种变化，包括:

This can be configured, however, via Assembly Binding Redirection. There are various options of what will happen here, including:

• 该引用可以说它不关心版本控制，在这种情况下，将加载最新版本.
• 您可以配置应用程序，方法是指定如何重定向绑定.
• GAC中的程序集可以是使用发布者策略进行设置，用于指定如何处理这个.

• The reference can say that it doesn't care about versioning, in which case the newest is loaded.
• You can configure your application in a way that you specify how to redirect the binding.
• The assembly in the GAC can be setup with a publisher policy that specifies how to handle this.
