Question

我有一个包含3个类库项目（业务逻辑，数据访问层，Web服务）的解决方案。

我可以在Visual Studio中构建解决方案。

但是，当构建任务在Azure DevOps中运行时，它会失败，并会出现以下错误：命名空间或类型不存在。错误是由于其中一个类库项目依赖于另一个。

这里可能是什么问题？

第二部分是，当我为Web应用程序添加构建任务时，如何确保Web应用程序可以从类库项目解决方案的第一次构建中正确引用DLLS（以便自行构建）正确）？

以下是解决方案文件的摘录-“未找到”错误与 MatterDBLibrary 项目有关。

 Project("{FAE04EC0-301F-11D3-BF4B-00C04F79EFBC}") = "MatterDBBusinessEntities", "MatterDBBusinessEntities\MatterDBBusinessEntities.csproj", "{EC049257-C855-47DC-A2DF-02910DBC34A3}"
EndProject

    Project("{FAE04EC0-301F-11D3-BF4B-00C04F79EFBC}") = "MattersDBService", "MattersDBService\MattersDBService.csproj", "{34F4FE24-948B-4EF2-8252-7FDA8430616F}"
EndProject

Project("{FAE04EC0-301F-11D3-BF4B-00C04F79EFBC}") = "MatterDBLibrary", 
    "MatterDBLibrary\MatterDBLibrary.csproj", "{D76D1BFC-8B1E-4A3F-AC76-3218CA28E5D7}"
    ProjectSection(ProjectDependencies) = postProject
        {34F4FE24-948B-4EF2-8252-7FDA8430616F} = {34F4FE24-948B-4EF2-8252-7FDA8430616F}
        {EC049257-C855-47DC-A2DF-02910DBC34A3} = {EC049257-C855-47DC-A2DF-02910DBC34A3}
    EndProjectSection
EndProject

MatterDB参考：

<ProjectReference Include="..\MatterDBBusinessEntities\MatterDBBusinessEntities.csproj">
      <Project>{ec049257-c855-47dc-a2df-02910dbc34a3}</Project>
      <Name>MatterDBBusinessEntities</Name>
</ProjectReference>

MatterDBService参考：

<ProjectReference Include="..\MatterDBBusinessEntities\MatterDBBusinessEntities.csproj">
      <Project>{ec049257-c855-47dc-a2df-02910dbc34a3}</Project>
      <Name>MatterDBBusinessEntities</Name>
</ProjectReference>

第三个项目（MatterDBBusinessEntities）与以上两个项目无关。

提前谢谢。

Answer 1

但是，当构建任务在Azure DevOps中运行时，它会失败，并会出现以下错误：命名空间或类型不存在。错误是由于其中一个类库项目依赖于另一个。

由于一个类库项目依赖于另一个，因此，要解决此问题，最好的解决方案是为类库项目添加项目引用。然后在构建任务上，在“解决方案”选项中选择解决方案文件.sln文件：

然后，MSBuild / Visual Studio将首先基于项目文件中的引用关系选择构建引用的项目，例如<ProjectReference Include="..\TestReferenceApp\TestReferenceApp.csproj">，然后将输出复制到引用项目的目录中。

第二部分是，当我为Web添加构建任务时应用程序，如何确保Web应用程序可以引用从类库项目的第一个生成正确地DLLS 解决方案（以便正确构建自己）？

就像第一个问题的答案一样，将项目引用添加到Web应用程序。如果添加引用仅限于您，则可以先构建类库项目，然后添加copy task将库复制到Web应用程序的输出。或者，您可以将类库项目打包为nuget软件包，然后将此nuget软件包添加到Web应用程序中。

希望这会有所帮助。
