嵌入一​​个免注册COM清单为C＃DLL与本地/管理环境 [英] Embed a Registration-Free COM manifest into a C# dll with native/managed environment

问题描述

我目前工作的一个混合的本机/托管应用程序链，它采用免注册的COM。下图说明了这一点：

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

C＃的包装DLL已经使用tlbimp.exe是实用程序创建的。这允许每个C＃的可执行文件来访问本地类型和方法在COM的DLL。在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.

一切工作正常，当基于客户端RegFree COM体现嵌入在C＃中的可执行文件。不过，我想移动和统一这些清单文件到C＃DLL，这将缓解版本信息显著的维护和同步。

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.

由于Visual Studio不会提供一个选项，以嵌入清单文件转换成一个C＃类库，我试图提取，修改和重新嵌入DLL的默认清单与清单工具（mt.exe）。这似乎已经奏效，因为C＃DLL现在公开以下清单，当被询问与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> 

不过，可执行拒绝工作，每一个抱怨COM类工厂未能找到丢失的COM组件。

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

有什么我已经在这里忽略了？谢谢你。

Is there something I have overlooked here? Thanks.

推荐答案

我把它通过pinvoking相应的激活上下文职能工作。由于汉斯帕桑特中的提示。

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