我正在尝试使用bitbucket管道为我的.NET项目编写，使用WindowsForms编写C＃7.0 . 但我总是得到一个错误 . 我用Unittests创建了一个简单的WinForm项目，只是为了尝试bitbucket管道，然后再将它用于我的actuall项目 . 我的项目结构如下所示：

justtestin
 |
 +-- .gitignore
 |
 +-- bitbucket-pipelines.yml
 |    
 +-- JustTestin
 |  |  
 |  +-- bin
 |  |
 |  +-- obj
 |  |
 |  +-- packages
 |  |
 |  +-- Properties
 |  |
 |  +-- TestResults
 |  |
 |  +-- JustTestin.csproj
 |  |
 |  +-- JustTestin.sln
 |  |
 |  +-- MyClass.cs
 |  |
 |  +-- MyFirstForm.cs
 |  |
 |  +-- MyFirstForm.Designer.cs
 |    
 +-- JustTestinTest
    |  
    +-- bin
    | 
    +-- obj
    |
    +-- Properties
    |
    +-- JustTestinTest.csproj
    |
    +-- MyClassTest.cs
    |
    +-- packages.config

我得到了几个错误，因为我尝试使用不同的设置配置bitbucket-pipelines.yml文件 . 但是他们中的非实际上对我来说效果很好 . 以下是一些示例错误：

- MSBUILD : error MSB1003: Specify a project or solution file. The current `working directory does not contain a project or solution file.`


- dotnet-test Error: 0 : System.InvalidOperationException: JustTestinTest/project.json does not exist.

等等 .

我使用Visual Studio 2017 Professional . 在我的本地机器上一切都很适合我 . 构建应用程序并运行单元测试不会报告任何错误 .

我现在的问题是：是否有适合我的bitbucket-pipelines.yml文件的设置？

谢谢...
