When I run my Devops pipeline, it creates the WebApp.zip file for a .NET Core web app on Azure.

That file includes all my content and a wwwroot folder.

When I run the app, I get 404 for files outside the wwwroot folder that is generated in the pipeline. For example a folder called frontendfiles which contains CSS.

I have tried using the StaticFileOptions like this:

StaticFileOptions staticFileoptions = new StaticFileOptions
      {
          FileProvider = new PhysicalFileProvider(
          Path.Combine(env.ContentRootPath, "frontendfiles")),
          RequestPath = "/frontendfiles"
      };
app.UseStaticFiles(staticFileoptions);
app.UseStaticFiles();

When I view the file structure via FTP I can see that the root is wwwroot, then there is another wwwroot inside which is generated by the pipeline.

The frontendfiles folder sits under the root wwwroot folder, but outside the wwwroot sub folder.

I have spent days trying to figure this out without success so hoping someone might point me in the right direction.
