SGEN、InternalsVisibleTo 和程序集签名

我正在尝试做一些有点不寻常的事情...

我有这个类 Foo ：

public class Foo
{
    public Foo(string name)
    {
        this.Name = name;
    }

    internal Foo()
    {
    }

    public string Name { get; internal set; }
    public int Age { get; set; }
}

注意 Name 的内部设置器和内部默认构造函数。这通常会阻止 XML 序列化，但我还使用 InternalsVisibleTo 将 XML 序列化程序集标记为“朋友”：

[assembly: InternalsVisibleTo("TestXML2008.XmlSerializers")]

并且我添加了一个 MSBuild 任务来预生成序列化程序集：

<Target Name="AfterBuild" DependsOnTargets="AssignTargetPaths;Compile;ResolveKeySource" Inputs="$(MSBuildAllProjects);@(IntermediateAssembly)" Outputs="$(OutputPath)$(_SGenDllName)">
  <SGen BuildAssemblyName="$(TargetFileName)" BuildAssemblyPath="$(OutputPath)" References="@(ReferencePath)" ShouldGenerateSerializer="true" UseProxyTypes="false" KeyContainer="$(KeyContainerName)" KeyFile="$(KeyOriginatorFile)" DelaySign="$(DelaySign)" ToolPath="$(SGenToolPath)">
    <Output TaskParameter="SerializationAssembly" ItemName="SerializationAssembly" />
  </SGen>
</Target>

这工作正常：Name 属性已正确序列化和反序列化。

现在，我想签署我的程序集...所以我为我的程序集定义一个密钥文件，并修改 InternalsVisibleTo 声明以匹配该密钥：

[assembly: InternalsVisibleTo("TestXML2008.XmlSerializers, PublicKey=c5cd51bf2cc4ed49")]

但现在 SGEN 失败：

无法生成临时类（结果=1）。
无法分配属性或索引器“TestXML2008.Foo.Name”——它是只读的

SGEN 任务应该通过宏选择密钥文件，但显然这还不够......我还尝试在中显式指定密钥文件SGEN任务，没有成功。当我在命令行上使用 sgen.exe 时，我得到了相同的结果......

我错过了什么吗？我不明白为什么当我签署程序集时它不起作用......

原文

I'm trying to do something a bit unusual...

I have this class Foo :

public class Foo
{
    public Foo(string name)
    {
        this.Name = name;
    }

    internal Foo()
    {
    }

    public string Name { get; internal set; }
    public int Age { get; set; }
}

Notice the internal setter for Name, and the internal default constructor. This would normally prevent the XML serialization, but I also marked the XML serialization assembly as "friend" with InternalsVisibleTo :

[assembly: InternalsVisibleTo("TestXML2008.XmlSerializers")]

And I added a MSBuild task to pre-generate the serialization assembly :

<Target Name="AfterBuild" DependsOnTargets="AssignTargetPaths;Compile;ResolveKeySource" Inputs="$(MSBuildAllProjects);@(IntermediateAssembly)" Outputs="$(OutputPath)$(_SGenDllName)">
  <SGen BuildAssemblyName="$(TargetFileName)" BuildAssemblyPath="$(OutputPath)" References="@(ReferencePath)" ShouldGenerateSerializer="true" UseProxyTypes="false" KeyContainer="$(KeyContainerName)" KeyFile="$(KeyOriginatorFile)" DelaySign="$(DelaySign)" ToolPath="$(SGenToolPath)">
    <Output TaskParameter="SerializationAssembly" ItemName="SerializationAssembly" />
  </SGen>
</Target>

This works fine : the Name property is correctly serialized and deserialized.

Now, I want to sign my assembly... So I define a key file for my assembly, and I modify the InternalsVisibleTo declaration to match the key :

[assembly: InternalsVisibleTo("TestXML2008.XmlSerializers, PublicKey=c5cd51bf2cc4ed49")]

But now SGEN fails :

Unable to generate a temporary class (result=1).
Property or indexer 'TestXML2008.Foo.Name' cannot be assigned to -- it is read only

The SGEN task should pick the key file through the macros, but apparently that's not enough... I also tried to specify the key file explicitly in the SGEN task, without success. I have the same result when I use sgen.exe on the command line...

Am I missing something ? I can't understand why it doesn't work when I sign the assembly...
