c# - 无法在面向 .NET 3.5 的 Visual Studio 2012 中的 C# 项目中使用 CLI 类库中的 CLR 类型并使用 Windows7.1SDK 工具集进行编译

标签 c# c++ .net visual-studio-2012 clr

我有一个 VS2012 解决方案，其中包含一个针对 .NET 3.5 的 C++/CLI 类库项目，并使用 Windows7.1SDK 作为平台工具集，根据 MSDN是在不安装相应版本的工具集(即 Visual Studio 2008)的情况下针对以前版本的框架的正确方法:

You can use the Windows7.1SDK platform toolset to target the .NET Framework 2.0, 3.0, 3.5, and 4, and the x86, Itanium, and x64 platforms.

CLI/C++ 项目启用了公共(public)语言运行时支持 (/clr)。

我想在 C# 中使用在 C++ 项目中声明的类，因此我创建了一个面向 .NET 3.5 的 C# 项目并添加了对 CLI 项目的引用。但是，在构建使用 C++ 项目中声明的类型的 C# 时，我得到:找不到类型或命名空间名称“Class1”(是否缺少 using 指令或程序集引用？)

奇怪的是，IDE 似乎确实能够找到类型(绿色)并且 IntelliSense 显示了该类型可用的方法。

解决方案结构

Solution Test1
|
| ClassLibrary1 (C++)
|    Class1.h
|    Class1.cpp
|
| Test1 (C#)
|    TestClass1.cs

类库1.h

public ref class Class1
{
public:
    Class1(unsigned short int initValue);
    ~Class1(void);

    void Init(unsigned short int init);
    void Input(unsigned char data);
    unsigned short int Getalue(void);

private:
    unsigned short int _value;
};

TestClass1.cs

static void Main(string[] args)
{
    var t = new Class1(0xFFFF); //also tried with global::Class1, no cigar
}

更奇怪的是，VS 将对 C++/CLI 项目的引用识别为目标 v4.0.30319。

它也给出类似的警告

Warning 5 The primary reference "D:\Test1\Debug\ClassLibrary1.dll" could not be resolved because it has an indirect dependency on the .NET Framework assembly "System.Xml, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089" which has a higher version "4.0.0.0" than the version "2.0.0.0" in the current target framework. Test1

我不明白它是从哪里得到这与 .NET 4 有任何关系的想法。我在 Debug 文件夹中找到了 ClassLibrary1.dll.metagen，这是我能想到的唯一地方这些对程序集 v4 的引用:

ImageRuntimeVersion: v4.0.30319

    Input(Byte): PrivateScope, Public, HideBySig
    GetValue(): PrivateScope, Public, HideBySig
    Dispose(): PrivateScope, Public, Final, Virtual, HideBySig

我试过编辑文件但没有成功。我还尝试在 C++ 项目中将工具集切换到 Visual Studio 2012 (v110)，但没有成功。任何帮助将不胜感激。

似乎有人已经有了 exact same issue在 VS 论坛网站上，但最终放弃了尝试解决它。​​

最佳答案

所以在 this answer 中找到 VS2010 Express 的链接之后(它不再在 VS 网站上可用)并安装它，我发现它也无法使用 VS2010 构建 3.5；你需要安装2008!这绝对是一场噩梦，但是 this answer 中的解决方法终于允许我在 VS2012 上构建目标 .NET 3.5。

<rant>从实现这一点所花费的时间来看(即便如此，有变通办法)，人们只能得出结论，如果开发人员不瞄准最新和最好的，微软显然就赚不到钱。我不明白为什么要将工具版本与框架紧密结合。 </rant>
