Answer 1

It took me some time to get it running so i want to share my solution here

    string vpath = s.GetValue("VirtualPath") ?? string.Empty;

    if (string.IsNullOrWhiteSpace(vpath))
    {
        app.UseSwagger();
        app.UseSwaggerUI(c => { c.SwaggerEndpoint("/swagger/v1/swagger.json", endpointName); });
    }
    else
    {
            app.UseSwagger(c =>
            {
                //no virtual path in the roue template it is relative 
                c.RouteTemplate = $"swagger/{{documentName}}/swagger.json";
                //c.PreSerializeFilters.Add((swagger, request) => swagger.BasePath = $"/{vpath}");
            });
            app.UseSwaggerUI(options =>
            {
                //options.RoutePrefix = vpath;
                //gives the location of the gennerated json file to the UI
                //start with / to create an absolute path from the base directory
                options.SwaggerEndpoint($"/{vpath}/swagger/v1/swagger.json", endpointName);
            });
    }
