如何使用.Net核心“外部别名”装配体？ [英] How to `extern alias` an assembly with .Net core?

问题描述

TLDR ：标题中几乎所有内容。

TLDR: Everything is pretty much in the title.

假设您的 project.json 使用两个具有相同名称（相同名称，相同名称空间）的两种类型的软件包。

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

如何使用这些类型之一？

How to use one of thoses types ?

通过对.Net进行分类，这很容易。只需使用 外部别名 。

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

但是如何使用.net core 做到这一点？
我没有在 package.json 中看到任何选项，可以让我像在程序集引用属性窗口中那样定义别名。

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.

我设法找到的这个问题的唯一提及是这里

您可以使用MSBuild Target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>
