Is it possible to output a .json file from a source generator or does it only work with c# files?

   private void Generate(SourceProductionContext context, (Compilation compilation, ImmutableArray<(string, string)> files) value)
    {
        var content = "{}";

        context.AddSource("test.json", content);
    }

   private void Generate(SourceProductionContext context, (Compilation compilation, ImmutableArray<(string, string)> files) value)
    {
        var content = "{}";

        context.AddSource("test.json", content);
    }

this is what i have currently and it generates a "test.json.cs" file instead

It might be possible to output it as a resource or a const string Source generators, IIRC, hook directly into the compiler and emit the files there They don't work like T4 templates

i see.. how would i output as a resource?

Huh, now that I'm looking at it, I'm not sure it's possible after all... Maybe peeps in #roslyn would know more Only thing I could find is this GH issue

atm SGs can only produce source I asked a similar question recently https://discord.com/channels/143867839282020352/598678594750775301/1195136293181591602

random question, what approach would you take to generate something during your build that is an SG isn't appropriate for? separate console project that you msbuild Exec (how would ensure the project gets built first?) MSBuild Task? (those looked awkward to have in the same project tho)

FWIW I generate a manifest of JS files for use with a webworker in one of my projects, and I do it with... just a normal method that uses Directory and File classes to do that lmao Then I just call await JsManifest.Generate() on startup and call it a day

Only C# files

C# file with a raw string literal json seems like a workaround
