在GAC之外的COM +应用程序中注册.NET程序集

Question

我开发了一个.NET程序集(.NET 4.0,强名称),它公开了两个服务组件.程序集(dll)应该托管在COM +应用程序中,并使用COM +属性(程序集和组件级别)进行修饰.例如,程序集级别属性:

//COM+ Attributes
[assembly: ApplicationID("MY_APP_GUID")] //GUID of the COM+ app
[assembly: ApplicationName("MyComPlusAppName")] //Name of the COM+ app
[assembly: ApplicationActivation(ActivationOption.Server)] //The app is hosted in it own dllhost process (out-of-process)
[assembly: ApplicationAccessControl(AccessChecksLevel = AccessChecksLevelOption.ApplicationComponent, Authentication = AuthenticationOption.None, ImpersonationLevel = ImpersonationLevelOption.Delegate, Value = false)]
[assembly: Description("COM+ app description")]

目前(开发原因),我一直在运行以下脚本来创建COM +应用程序并注册程序集(包含其所有组件):

%windir%\Microsoft.NET\Framework\v4.0.30319\RegSvcs.exe /appdir:"%CD%" MyComPlusAssembly.dll 

上面的批处理文件将根据程序集装饰属性创建(在单次运行中)COM +应用程序,在COM +应用程序中注册MyComPlusAssembly.dll文件并在其中注册所有ComVisible组件,因此所有内容都可见并在dcomcnfg中按预期配置.此命令还将生成一个全新的TLB文件.程序集是使用AnyCPU构建的,因此在x64版本的Windows上,dllhost.exe进程将以64位运行,而在x86版本的Windows上,它将以32位运行.另外,我的dll文件,应该不放在GAC(这就是为什么我使用Regsvcs.exe的命令行实用程序的/ APPDIR开关).使用上述批处理文件安装COM +程序集时,所有工作都按预期工作.

我开始为我的应用程序编写一个Wix(v3.6)部署项目,它应该做同样的事情,即:创建COM +应用程序,注册.NET程序集和所有ComVisible组件.请注意,这次我依赖于TLB文件随安装程序一起提供(*.msi).TLB由构建过程生成(VS 2010).为实现上述目的,我添加了以下Wix组件(受Wix COM +扩展文档的启发 - WixComPlusExtension):

   <DirectoryRef Id="INSTALLDIR_SERVER">
      <Component Id="cmp_MyComPlusAssembly.dll" Guid="COMPONENT_DLL_GUID">
        <File Id="MyComPlusAssembly.dll" Name="MyComPlusAssembly.dll" DiskId="1" Source="..\install\$(var.Configuration)\Server\MyComPlusAssembly.dll" KeyPath="yes"/>
        <CreateFolder>
          <util:PermissionEx GenericAll="yes" User="NT AUTHORITY\LocalService"/>
        </CreateFolder>
        <complus:ComPlusApplication Id="ComPlusServerApp"
                                    AccessChecksLevel="applicationComponentLevel"
                                    Activation="local"
                                    ApplicationAccessChecksEnabled="no"
                                    ApplicationDirectory="[INSTALLDIR_SERVER]"
                                    ApplicationId="MyComPlusAssembly.dll"
                                    Authentication="none"
                                    Description="MyComPlusAssembly.dll"
                                    Identity="NT AUTHORITY\LocalService"
                                    ImpersonationLevel="delegate"
                                    IsEnabled="yes"
                                    RunForever="yes"
                                    Name="MyComPlusApp"
                                    Deleteable="yes">
          <complus:ComPlusAssembly Id="ComPlusServerAssembley"
                                   DllPath="[#MyComPlusAssembly.dll]"
                                   TlbPath="[#MyComPlusAssembly.tlb]"
                                   Type=".net"
                                   DllPathFromGAC="no">

            <complus:ComPlusComponent Id="COMObject_1"
                                      CLSID="COM_OBJ_1_GUID"
                                      Description="Object 1"
                                      IsEnabled="yes"/>

            <complus:ComPlusComponent Id="COMObject_2"
                                      CLSID="COM_OBJ_2_GUID"
                                      Description="Object 2"
                                      IsEnabled="yes"/>

          </complus:ComPlusAssembly>
        </complus:ComPlusApplication>        

      </Component>
      </Component>

      <Component Id="cmp_MyComPlusAssembly.tlb" Guid="COMPONENT_TLB_GUID">
        <File Id="cmp_MyComPlusAssembly.tlb" Name="cmp_MyComPlusAssembly.tlb" DiskId="1" Source="..\install\$(var.Configuration)\Server\cmp_MyComPlusAssembly.tlb" KeyPath="yes"/>
      </Component>

    </DirectoryRef>   

MSI项目成功构建,但安装过程失败,并在尝试注册dll后立即回滚.可以在日志中找到以下错误(对于BOTH x86和x64版本):

Action 16:33:37: RegisterComPlusAssemblies. Registering COM+ components
RegisterComPlusAssemblies: DLL: C:\Program Files\MyApp\Server\MyComPlusAssembly.dll
ComPlusInstallExecute:  Registering assembly, key: ComPlusServerAssembley
ComPlusInstallExecute:  ExceptionInfo: Code='0', Source='System.EnterpriseServices', Description='Failed to load assembly 'c:\program files\myapp\server\MyComPlusAssembly.dll'.', HelpFile='', HelpContext='0'

ComPlusInstallExecute:  Error 0x80020009: Failed to register assembly, key: ComPlusServerAssembley
ComPlusInstallExecute:  Error 0x80020009: Failed to register assemblies

上述错误可能意味着缺少在COM +应用程序中注册的dll,即文件不在磁盘上.虽然安装过程很快,但我从未见过将MyComPlusAssembly.dll文件复制到磁盘(到[INSTALLDIR_SERVER]),当安装开始回滚(包括TLB)时,所有其他文件都在磁盘上.这是时间问题吗？

观察:

1. 这两种版本的安装程序(x64和x86)都会发生这种情况.
2. 删除" <complus:ComPlusAssembly...>"标记(包括嵌套组件)时,安装成功并创建一个(空)应用程序,即 - 只有容器",没有任何程序集或COM +托管组件.
3. 我尝试添加第三个" <Component.../>",它创建一个简单的注册表项并将所有" <complus:ComPlusApplication.../>"代码移动到它.复制完所有文件后将执行此组件.与上面的日志相同的结果(错误).

我在这里错过了什么？

这对我有用：

<Component Id="cmp502C27298171EA4E966A386B188D734C" Guid="{7A5ADAA7-8D43-4E91-80DB-764BB1E13887}">

</Component>

也许您应该省略 DllPathFromGAC 属性？

编辑：这是在 Windows XP 和 Windows 2008 32 位上的 Wix v3.6 上。另一件需要确保的事情是您还安装了 COM+ 组件所需的所有依赖项。在安装过程中使用程序集绑定日志查看器查看您的组件是否由于缺少或不正确（错误版本）依赖项而无法加载。
