Url is missing from appinsights logs for requests if use FunctionStartup

1. Run any number of load on sandbox
2. Go to appinsights -> Logs
3. Query for the following -
requests | where cloud_RoleName contains "test" | order by duration desc | project itemType, cloud_RoleName, url, appName, timestamp, name, cloud_RoleInstance.

What we have observed - If Startup class inherit IWebJobStartup then we are getting URL in appinsights logs for request, but if Startup class inherit FunctionStartup then we are not getting Url in appinsights logs.

We want to use Startup class Inherit FunctionStartup as we have written so much code based upon that in so many services. And we want to use constructor DI which is not possible in IWebJobStartup (as per sample which I have).


1. Getting URL in appinsight logs if we use below code in startup class

[assembly: WebJobsStartup(typeof(Startup))]
namespace TestApplicationWebJob.Infrastructure
{
[ExcludeFromCodeCoverage]
internal class Startup : IWebJobsStartup
{
static string appInstanceId = Guid.NewGuid().ToString();
public void Configure(IWebJobsBuilder builder)
{
#pragma warning disable CS0618 // Type or member is obsolete
builder.AddDependencyInjection(ConfigureServices);
builder.AddSwashBuckle(Assembly.GetExecutingAssembly(), opts =>
{

2. Not getting URL in appinsights logs, if we use below code in startup class

[assembly: FunctionsStartup(typeof(Startup))]
namespace TestApplicationFunc.Infrastructure
{
[ExcludeFromCodeCoverage]
public class Startup : FunctionsStartup
{
public override void Configure(IFunctionsHostBuilder builder)
{
RegisterServices(builder.Services);

builder.AddSwashBuckle(Assembly.GetExecutingAssembly(), opts =>
{
opts.SpecVersion = OpenApiSpecVersion.OpenApi3_0;
opts.Documents = new[]
{
new SwaggerDocument
{

Start by comparing the two startup configurations shown in the issue: IWebJobsStartup and FunctionsStartup. Reproduce the request query in Application Insights with each configuration, then trace how request URLs are recorded and how dependency injection is registered. Done means URLs appear for requests when using FunctionsStartup without losing the required constructor DI behavior.
