JetBrains Rider debugger not connecting

[Daniel15]

I'm using JetBrains Rider on Fedora. I created a new project using this template. It runs fine, but when I try to run with the debugger, the app never starts. Even if I put a breakpoint at the start of the first line of Main, it never gets hit.

The debugger works fine for a basic console app, and for an ASP .NET web app. It's just Gir.Core Gtk projects that I'm encountering this issue with.

Any ideas?

It turns out this is something to do with PublishSingleFile. For now I've pulled that out into a PropertyGroup that only applies for release builds:

    <PropertyGroup>
        <OutputType>WinExe</OutputType>
        <TargetFramework>net8.0</TargetFramework>
        <ImplicitUsings>enable</ImplicitUsings>
        <Nullable>enable</Nullable>
        <PublishTrimmed>false</PublishTrimmed>
        <SelfContained>true</SelfContained>
    </PropertyGroup>

    <PropertyGroup Condition="'$(Configuration)' == 'Release'">
        <PublishSingleFile>true</PublishSingleFile>
    </PropertyGroup>

Edit: Turns out this is a long-standing bug in Rider: https://youtrack.jetbrains.com/issue/RIDER-56918/Cannot-start-debugging-net5-project-on-Linux-when-using-PublishSingleFile-in-.proj-file

It might be worth mentioning in the readme, in a comment in the csproj file, or just only using PublishSingleFile for release builds by default? (I'm not sure it has value in debug builds)
