Get XML comments output file location for ASP Core

Question

I've added Swashbucklepackage to my ASP Core project.

I'd like to configure Swagger to use auto-generated by VS xml comments.

The problem is that I can't find the way to get that location:

1. PlatformServices.Default.Application.ApplicationBasePath - points to the project root path
2. Directory.GetCurrentDirectory() - the same
3. Path.GetFullPath(".") - the same
4. IHostingEnvironment.WebRootPath - the same

Output folder configured in <project>.xproj by BaseIntermediateOutputPath option.

But I can't get this location in runtime.

var pathToDoc = "????";
options.OperationFilter(new Swashbuckle.SwaggerGen.XmlComments.ApplyXmlActionComments(pathToDoc));

Bad solutions I see:

1. add configuration option to AppSettings.json
2. Relative path from project path (as I'm configuring bin output path).

But I'd like to use this with Docker, CI, localhost, so I don't think this would be the best solution to use hard-coded solution..

Answer 1

You can try the following function to get the XML File path

 private string GetXmlCommentsPath()
        {
            var app = PlatformServices.Default.Application;
            return System.IO.Path.Combine(app.ApplicationBasePath, System.IO.Path.ChangeExtension(app.ApplicationName, "xml"));
        }

The xml file has the same name as the app. I am currently using this code in my project and it works fine.
