This is just awesome!

I tweeted this and people wanted more details for reproducing it. If I create a new F# Console App and make this my Program.fs

open System

[<EntryPoint>]
let main argv =
    let txt = IO.File.ReadAllText "version.txt"
    printfn "%s" txt
    0

The .fsproj is just a normal netcoreapp2.1.

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

  <PropertyGroup>
    <OutputType>Exe</OutputType>
    <TargetFramework>netcoreapp2.1</TargetFramework>
    <RootNamespace>SourceLinkTest._15._8</RootNamespace>
  </PropertyGroup>

  <ItemGroup>
    <Compile Include="Program.fs" />
  </ItemGroup>

</Project>

When it breaks, it has download and opened this file: C:\Users\taggac\AppData\Local\SourceServer\b10415eb2a144607e44abde47868668ad70b9b7cb26b993e32e7bc8fce84d98e\src\mscorlib\shared\System\IO\FileStream.Windows.cs

As seen in this screenshot:

deselect Enable Just My Code

The only think I changed in Debugging General settings to make this work I believe.

Microsoft Symbol Servers

I believe these are all the default settings, but let me know if they are not. The symbols (pdb files) are downloaded from the Microsoft Symbol Servers and those pdb files have source link enabled.

I was able to step into System.Console.WriteLine just fine.

open System

[<EntryPoint>]
let main argv =
    Console.WriteLine "hello"
    0

Debug > Windows > Modules

Open up the Modules window in Visual Studio to see what symbols files are beings used.

It has source link enabled:
