如何使用 .Net 核心`extern alias` 程序集? [英] How to `extern alias` an assembly with .Net core?

问题描述

TLDR:所有内容都在标题中.

TLDR: Everything is pretty much in the title.

假设您的 project.json 使用了两个包，它们具有两种名称相同的类型(名称相同，命名空间相同).

Suppose that your project.json uses two packages that have a two types which are named the same (same name, same namespace).

如何使用其中一种类型?

How to use one of thoses types ?

使用 .Net 分类，这很容易.只需使用 extern 别名.

With classing .Net, that's easy. Just use an extern alias.

但是你如何使用 .net core 来做到这一点?我在 package.json 中没有看到任何让我定义别名的选项，就像我在程序集引用属性窗口中所做的那样.

But how do you do that using .net core ? I dont see any option in package.json that would let me define an alias like I would do in an assembly reference property window.

我设法找到的唯一提到的这个问题是这里

您可以通过使用 MSBuild 目标来解决.将此代码段放入 Directory.Build.targets:

You can workaround by using an MSBuild Target. drop this snippet into Directory.Build.targets:

<Target Name="AddPackageAliases" BeforeTargets="ResolveReferences" Outputs="%(PackageReference.Identity)">
    <PropertyGroup>
        <AliasPackageReference>@(PackageReference->'%(Identity)')</AliasPackageReference>
        <AliasName>@(PackageReference->'%(Alias)')</AliasName>
    </PropertyGroup>

    <ItemGroup>
        <ReferencePath Condition="'%(FileName)'=='$(AliasPackageReference)'">
            <Aliases>$(AliasName)</Aliases>
        </ReferencePath>
    </ItemGroup>
</Target>

然后在 PackageReference 节点的 csproj 中使用它，如下所示:

and then use it in your csproj in your PackageReference nodes like this:

<ItemGroup>
    <PackageReference Include="StackExchange.Redis.StrongName" Version="1.2.6" Alias="signed" />
</ItemGroup>
