是否可以将Yaml模板嵌套在另一个Yaml模板中？

我在不同的Git存储库中有多个NuGet项目，并且我正在尝试对在nuget.org上发布NuGets的过程进行模板化。

因此，我创建了一个名为“ devops-templates”的git存储库，做了一个第一个yaml模板，请确保它可以工作，然后将其划分为4个yaml模板（构建解决方案，生成包，运行单元测试，发布），并进行引用将它们放入全局yaml模板。

问题是，当我尝试在管道中使用此全局模板时，出现了错误

/Net/Utilities/BuildSolution.yml@templates (Line: 33,Col: 18): A template expression is not allowed in this context,/Net/Utilities/BuildSolution.yml@templates (Line: 36,Col: 21): A template expression is not allowed in this context,/Net/Utilities/BuildSolution.yml@templates (Line: 48,Col: 24): A template expression is not allowed in this context,/Net/Utilities/BuildSolution.yml@templates (Line: 53,Col: 28): A template expression is not allowed in this context,/Net/Utilities/BuildSolution.yml@templates (Line: 54,Col: 26): A template expression is not allowed in this context,/Net/Utilities/BuildSolution.yml@templates (Line: 59,/Net/Utilities/BuildSolution.yml@templates (Line: 60,Col: 22): A template expression is not allowed in this context,/Net/Utilities/BuildSolution.yml@templates (Line: 61,Col: 32): A template expression is not allowed in this context,/Net/Utilities/BuildSolution.yml@templates (Line: 63,/Net/Utilities/BuildSolution.yml@templates (Line: 64,Col: 26): A template expression is not allowed in this context

我在microsoft文档https://docs.microsoft.com/en-us/azure/devops/pipelines/process/templates?view=azure-devops中进行了搜索，但未找到任何有关此信息。

下面是我的代码的一部分：

azure-pipelines.yml（主存储库）：

    (...)

BuildSolution.yml（devops模板存储库）：

          configuration: ${{ parameters.buildConfiguration}}

      - task: VSBuild@1
