Local assembly not found in debug mode VSCode

Question

I've tried to create a simple solution in .net5.0 with VSCode 1.52.0 on linux.

I've create 2 projects.

• CLIConsole.csproj with Program.cs

    using System;
    using MyLib;
  
    namespace CLIConsole
    {
        class Program
        {
            static void Main(string[] args)
            {
                Console.WriteLine("Hello World!");
                var mc = new MyClass();            
                mc.Test();
  
            }
        }
    }
  

and

• MyLib.csproj, with MyClass.cs

    using System;
  
    namespace MyLib
    {    public class MyClass
        {
            public void Test()
            {
                Console.WriteLine("This is a test");
            }
        }
    }
  

When I run in debug mode, I have this error :

Unhandled exception. System.IO.FileNotFoundException: Could not load file or assembly 'MyLib, Version=1.0.0.0, Culture=neutral, PublicKeyToken=null'. The system cannot find the file specified.

File name: 'MyLib, Version=1.0.0.0, Culture=neutral, PublicKeyToken=null'

NB : When in my Program.cs, I don't use MyLib, the debug works

I'm on linux and debug doesn't work because my assembly is not found.

I've tried this same solution in debug mode on Windows (always with VSCode), every things works.

My launch.json :

        }
    ]
}

        {

            "type": "process",

                "/property:GenerateFullPaths=true",
                "/consoleloggerparameters:NoSummary"
            ],
            "problemMatcher": "$msCompile"
        }
    ]
}

My 'dotnet --info' :

I don't know what to do, i am really blocked.

Thanks for your help !

Answer 1

I've found a solution, but I don't understand why my previous config doesn't work.

With this in CLIConsole.csproj, debug works :

<Project Sdk="Microsoft.NET.Sdk">

  <ItemGroup>    
     <Reference Include="..\MyLib\MyLib.csproj">       
       <HintPath>..\MyLib\bin\Debug\net5.0\MyLib.dll</HintPath>
     </Reference>
    </ItemGroup>

  <PropertyGroup>
    <OutputType>Exe</OutputType>
    <TargetFramework>net5.0</TargetFramework>
  </PropertyGroup>

</Project>

But with that, it doesn't work :

<Project Sdk="Microsoft.NET.Sdk">

  <ItemGroup>
    <ProjectReference Include="..\MyLib\MyLib.csproj" />
  </ItemGroup>

  <PropertyGroup>
    <OutputType>Exe</OutputType>
    <TargetFramework>net5.0</TargetFramework>
  </PropertyGroup>

</Project>

That is very strange...
