突然,我的整个项目完全停止编译,显示以下消息:

程序'path_to_obj_project_folder'不包含适用于入口点的静态'Main'方法

我没有对项目属性进行任何更改,只添加了一些类,将其他一些类移动到文件夹中.它是一个WPF应用程序项目,所以应该没问题.入口点应该是它,文件App.xaml根本没有修改:(

我该怎么办才能让它再次发挥作用？

我正在尝试使用Microsoft.Build中的类来构建项目.

代码是:

var project = new ProjectInstance(CS_PROJ_FILE);
project.Build();

然而,它抛出以下异常:

Microsoft.Build.Shared.InternalErrorException occurred
  HResult=0x80131500
  Message=MSB0001: Internal MSBuild Error: Type information for Microsoft.Build.Utilities.ToolLocationHelper was present in the whitelist cache as Microsoft.Build.Utilities.ToolLocationHelper, Microsoft.Build.Utilities.Core, Version=15.1.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a but the type could not be loaded. unexpectedly null
  Source=Microsoft.Build

我已经尝试将以下内容添加到包中(在net452和net7项目中):

• id ="Microsoft.Build"version ="15.1.1012"
• id ="Microsoft.Build.Framework"version ="15.1.1012"
• id ="Microsoft.Build.Runtime"version ="15.1.1012"
• id ="Microsoft.Build.Tasks.Core"version ="15.1.1012"
• id ="Microsoft.Build.Utilities.Core"version ="15.1.1012"

仍然得到相同的结果.

我也试过用BuildManager这样的:

var buildManager = new BuildManager();
buildManager.Build(new BuildParameters(),
                   new BuildRequestData(new ProjectInstance(CS_PROJ_FILE), 
                                        new[] {"Build"}));
