在 AssemblyInfo.cs 中引用项目时发布预编译的 ASP.NET 失败

Question

当我们尝试在发布期间启用预编译的情况下发布我们的 ASP.NET 应用程序时，它会失败，因为我们引用了AssemblyInfo.cs文件中的项目。

这是我们的项目结构：

Project.WebUI (ASP.NET MVC App on .NET 4.6.2)
Project.Resources (Class Library on .NET 4.6.2)
Project.Domain (Class Library on .NET 4.6.2)
Project.Services (Class Library on .NET 4.6.2)

在AssemblyInfo.cs的Project.WebUI我们引用Project.Resources是这样的：

using Project.Resources;

....

[assembly: AssemblyVersion(VersionInformation.FileVersion)]
[assembly: AssemblyFileVersion(VersionInformation.FileVersion)]
[assembly: AssemblyInformationalVersion(VersionInformation.ProductVersion)]

类VersionInformation是Project.Resources 中的静态类。

所有其他程序集也有这些参考 AssemblyVersion

当我们构建（调试或发布）时，它将通过而没有任何错误。当我们发布Project.WebUI项目时，我们收到以下错误：

Severity    Code    Description Project File    Line    Suppression State
Error       The type or namespace name 'Project' could not be found (are you missing a using directive or an assembly reference?)   Project.WebUI   Properties\AssemblyInfo.cs  3   
Error       The name 'VersionInformation' does not exist in the current context Project.WebUI   Properties\AssemblyInfo.cs  34  
Error       The name 'VersionInformation' does not exist in the current context Project.WebUI   Properties\AssemblyInfo.cs  35  
Error       The name 'VersionInformation' does not exist in the current context Project.WebUI   Properties\AssemblyInfo.cs  36  

我们的发布配置文件如下所示：

[X] Delete all existing files prior to publish
[X] Precompile during publishing

    Precompile Options
    [ ] Allow precompiled site to be updatable
    [ ] Emit debug information

    Merge Options
    [ ] Do not merge
    [ ] Do not merge. Create a separate assembly for each page and control
    [X] Merge all outputs to a single assembly
        "Project.Views"
        [X] Treat as library component (remove the AppCode.compiled file)

为什么会发生此错误，我们该如何解决？

这是错误的输出日志：

Answer 1

显然，在“发布”期间，csc.exe尝试编译AssemblyInfo.cs我们的Project.WebUI，但仅此文件。所以它无法正确引用Project.Resources.

我同事带来的解决方案对我们有用：

• 从所有AssemblyInfo.cs文件中删除所有版本属性
• 在Project.Resources项目中创建一个新文件，如AssemblyVersion.cs

• 该文件的唯一内容是像这样的版本属性

  [assembly: AssemblyFileVersion(VersionInformation.FileVersion)]
  

• AssemblyVersion.cs在每个其他项目中创建一个链接
