.net VS代码-更改为.csproj，can'；我不再调试了

我最近将project.json文件更改为.csproj文件

我尝试启动调试实例，但它返回错误：

Microsoft (R) Build Engine version 15.1.548.43366
Copyright (C) Microsoft Corporation. All rights reserved.
MSBUILD : error MSB1009: Project file does not exist.
Switch: /Users/my_user/sf-build-ms-port/sfbuild-DotNetCore/project.json

和一条错误消息：

The preLaunchTask 'build' terminated with exit code 1.

出现在顶部

这是我的.csproj文件：

<Project Sdk="Microsoft.NET.Sdk">
    <PropertyGroup>
        <TargetFramework>netcoreapp1.1</TargetFramework>
        <DebugType>portable</DebugType>
        <AssemblyName>sfbuild</AssemblyName>
        <OutputType>Exe</OutputType>
        <PackageId>sfbuild-DotNetCore</PackageId>
<PackageTargetFallback>$(PackageTargetFallback);dnxcore50</PackageTargetFallback>
<RuntimeFrameworkVersion>1.1.1</RuntimeFrameworkVersion>
</PropertyGroup>

  <ItemGroup Condition=" '$(TargetFramework)' == 'netcoreapp1.1' ">
    <PackageReference Include="System.Xml.XmlDocument" Version="4.3.0" />
    <PackageReference Include="System.Xml.XDocument" Version="4.3.0" />
    <PackageReference Include="System.Runtime.InteropServices" Version="4.3.0" />
     <PackageReference Include="System.Diagnostics.Process" Version="4.3.0" />
   </ItemGroup>

</Project>

我知道这个程序绝对是正确的。

我也有同样的问题。在新macbook上安装dotnet core后，如果不迁移到“新”csproj文件，我就无法构建。现在VSCode只是一个文本编辑器-从命令行启动后，我无法启动调试器或附加调试器。我已经确保运行了最新的vscode和c#扩展更新，但仍然无法工作。
