将无注册COM清单嵌入到具有本机/受管环境的C＃DLL中 [英] Embed a Registration-Free COM manifest into a C# dll with native/managed environment

问题描述

我目前正在使用混合本机/管理应用程序链，它使用免注册的COM。以下图片说明了这一点：

I'm currently working on a mixed native / managed application chain, which employs registration-free COM. The following image illustrates this:

使用tlbimp.exe实用程序创建了C＃包装器DLL。这允许每个C＃可执行文件访问COM DLL中的本机类型和方法。 COM DLL本身采用基于服务器的RegFree COM清单。

The C# wrapper DLL has been created using the tlbimp.exe utility. This allows each of the C# executables to access the native types and methods in the COM DLL. The COM DLL itself employs a server based RegFree COM manifest.

当基于客户端的RegFree COM清单嵌入在C＃可执行文件中时，一切正常。然而，我想将这些清单文件移动并统一到C＃DLL中，这将大大简化版本信息的维护和同步。

Everything works fine, when the client based RegFree COM manifests are embedded in the C# executables. However, I would like to move and unify these manifest files into the C# DLL, which would ease maintenance and synchronization of version info significantly.

因为Visual Studio不提供一个将清单文件嵌入到C＃类库中的选项，我已尝试使用清单工具（mt.exe）来提取，修改和重新嵌入DLL的默认清单。这似乎有效，因为C＃DLL现在公开以下清单，当被查询mt：

Because Visual Studio doesn't provide an option to embed a manifest file into a C# class library, I have tried to extract, modify, and re-embed the DLL's default manifest with the manifest tool (mt.exe). This seems to have worked, as the C# DLL now exposes the following manifest, when being queried with mt:

<?xml version="1.0" encoding="UTF-8" standalone="yes"?>
<assembly xmlns="urn:schemas-microsoft-com:asm.v1" manifestVersion="1.0"><assemblyIdentity name="FirstClient" version="1.0.0.0" processorArchitecture="msil"></assemblyIdentity><file name="FirstClient.dll" hashalg="SHA1"></file>
<dependency>
            <dependentAssembly>
                        <assemblyIdentity type="win32" name="atl" version="1.0.0.0"></assemblyIdentity>
            </dependentAssembly>
</dependency>
</assembly> 

然而，可执行文件拒绝工作，每个人抱怨COM类工厂无法找到缺少COM模块。

However, the executables refuse to work, each one complaining about the COM class factory not being able to find the missing COM module.

有没有我在这里忽略的东西？谢谢。

Is there something I have overlooked here? Thanks.

推荐答案

我通过引用适当的激活上下文功能来实现它的工作。感谢 Hans Passant 的提示。

I got it working by pinvoking the appropriate Activation Context functions. Thanks to Hans Passant for the hint.
