Visual studio 生成失败，因为找不到在生成时从t4转换的类型

我有一个ASP.NET核心项目，它的IDataService类型由T4模板生成。如果我手动让Visual Studio生成相应的.cs文件，然后构建项目，一切都很好：实现IDataService的各种类都可以找到接口的类型，一切都正常

因为手工转换所有这些模板既繁琐又容易出错（例如，从源代码管理克隆解决方案之后），所以我修改了.csproj文件，以便在每次构建之前转换所有t4模板。这很有效：当我构建项目时，所有T4模板都将生成最新的.cs文件

但是，当IDataService.cs还不存在，并且我构建了项目时，我可以看到IDataService.cs正在构建输出中创建（实际文件也显示在文件夹中），但是构建失败，因为找不到类型或命名空间IDataService。 如果我随后重新运行构建，IDataService.cs已经存在于上一个构建中，并且所有构建都很好

这里出了什么问题？为什么msbuild无法找到IDataService.cs，尽管它是在该生成上生成的

以下是构建输出（具有正常的详细性）：

这是.csproj文件：

我已经设法让它工作了，但我不太清楚为什么。我假设msbuild收集要生成的文件，然后转换t4模板，然后编译它收集的文件，因此不包括作为t4转换一部分生成的文件

项目文件为每个生成的文件列出了一个元素，文件名在“更新”属性中。将该属性更改为“Include”将导致文件包含在生成中，但这引入了一个新问题：现在，如果文件尚不存在，则生成将正常工作，但在后续生成中，由于文件位于项目目录中，MSBuild将隐式包含这些文件，并通过项目文件显式包含这些文件，导致生成错误

现在，我已经对这些元素中的每个元素使用了Condition属性来检查文件是否已经存在：如果已经存在，则不会包含该文件（因为msbuild已经隐式地包含了该文件）；如果没有，则会包含该文件（因为msbuild不知道该文件）。这是生成的.csproj文件：
