在自定义模块中包含Autofac.Module会破坏Orchard [英] Including Autofac.Module in custom module breaks Orchard

问题描述

请参见此处 此处，了解我为什么正在尝试这样做.

See here & here for why I'm trying to do this.

我有一个正在构建的自定义模块(和往常一样，它是在Orchard .sln中是它自己的.csproj)

I have a custom module that I'm building (and which is it's own .csproj in the Orchard .sln, as normal)

我有一个(相对复杂的)依赖项，我希望将其注入到Orchard中. 目前，如果我构建并运行该代码，它会非常高兴，直到遇到我的依赖项，此时它会成为null引用(正如我期望的那样).我可以访问管理站点和任何未引用依赖项的页面.

I have a (relatively complex) dependency that I wish to inject into Orchard. Currently if I build and run the code it's perfectly happy until it hits my dependency at which point it null-refs (as I'd expect it to). I can access the admin site and any pages that don't reference the dependency.

我在项目中添加了对Autofac的引用. ->很好.

I add a reference to Autofac to my project. -> All fine.

我添加以下类:

using System;
using Autofac;

namespace MyCustom.Module.Namespace
{
  public class LoaderModule
  {}
}

一切仍然很好-我重建并仍然获得预期的行为. 然后按照其他地方的说明，使LoaderModule从Autofac.Module派生:

Everything is still fine - I rebuild and still get the expected behaviour. Then I make my LoaderModule derive from Autofac.Module as instructed elsewhere:

using System;
using Autofac;

namespace MyCustom.Module.Namespace
{
  public class LoaderModule : Autofac.Module
  {}
}

突然我收到找不到资源".从IIS到整个Orchard网站的404代码-包括没有遇到依赖关系的管理网站和内容页面.

And suddenly I'm getting "The resource cannot be found." 404s from IIS for the entire Orchard site - including admin site and content pages which done't hit the dependency.

帮助！?

推荐答案

B！这是一个版本问题.

Bah! It was a versioning issue.

使用附加的调试器启动站点，并打破所有异常，结果如下:

Starting the site with debugger attached, and breaking on all exceptions revealed things like this:

{"Could not load file or assembly 'Autofac, Version=3.3.0.0, Culture=neutral, PublicKeyToken=17863af14b0044da' or one of its dependencies. The located assembly's manifest definition does not match the assembly reference. (Exception from HRESULT: 0x80131040)":"Autofac, Version=3.3.0.0, Culture=neutral, PublicKeyToken=17863af14b0044da"}

我从nuget中添加了Autofac，但是Orchard本身使用的捆绑版本有所不同. 删除我对Autofac的nuget引用，然后通过查找Autofac.dll的捆绑副本进行重新添加，使问题消除了.

I'd added Autofac from nuget, but Orchard itself was using a bundled version that was different. Removing my nuget reference to Autofac and re-adding by locating the bundled copy of Autofac.dll made the problem go away.
