.netlldb

Debug .NET Core 6 with lldb is showing assembly code on breakpoint, how do I show the dotnet code?

For lldb I want to see the .NET code when I hit a break point instead I see assembly code.

My .csproj:

<Project Sdk="Microsoft.NET.Sdk">
    <PropertyGroup>
       <OutputType>Exe</OutputType>
       <TargetFramework>net6.0</TargetFramework>
       <ImplicitUsings>enable</ImplicitUsings>
       <Nullable>enable</Nullable>
       <SelfContained>false</SelfContained>
       <PublishSingleFile>true</PublishSingleFile>
       <DebugType>embedded</DebugType>
    </PropertyGroup>
</Project>

I've also used

<Project Sdk="Microsoft.NET.Sdk">
    <PropertyGroup>
       <OutputType>Exe</OutputType>
       <TargetFramework>net6.0</TargetFramework>
       <ImplicitUsings>enable</ImplicitUsings>
       <Nullable>enable</Nullable>
       <PublishSingleFile>true</PublishSingleFile>
       <DebugType>embedded</DebugType>
    </PropertyGroup>
</Project>

My output

    $ lldb -o "target create hello" -o "bpmd hello.dll services.Hello.GetHello" -o "process launch -s" 
    Current symbol store settings:
    -> Cache: /home/shawn/.dotnet/symbolcache

    (lldb) process launch -s

    (lldb) process continue

   (lldb) process continue
    Process 1722 resuming
    Hi
    Process 1722 exited with status = 0 (0x00000000) 
    (lldb) exit

I've also tried

    $ lldb -o "target create dotnet" -o "settings set target.run-args ./hello.dll" -o "bpmd hello.dll services.Hello.GetHello" -o "process launch -s" 
    Current symbol store settings:

    Process 1559 launched: '/home/shawn/.dotnet/dotnet' (aarch64)
    (lldb) process continue
    Process 1559 resuming

        0xffff7e40fa64: mov    x29, sp
        0xffff7e40fa68: str    xzr, [x29, #0x10]
        0xffff7e40fa6c: str    x0, [x29, #0x18]
        (lldb) process continue
    Process 1559 resuming
    Hi
    Process 1559 exited with status = 0 (0x00000000) 
    (lldb) exit

Any thoughts on how I can output the C# code in the breakpoint?

Expecting: C# Code

I've tried building with different .csproj setting to include the pdb, along with running with .NET and stand alone

Solution

  • At the moment it is not supported by the dotnet team. I switch to netcoredbg
