Hi callykalpana,
How do I configure VS to start any web forms using IIS manager installed on Windows 10 instead of opening the IIS Express every time I tried to use the start with or without debugging option?
Firstly, please make sure you meet
the requirements for local IIS debugging.
- Select Development time IIS support when installing Visual Studio. (If necessary, rerun the Visual Studio Installer, select Modify, and add this component.)
- Be running Visual Studio as an administrator.
- Install and correctly configure IIS with the appropriate version(s) of ASP.NET and/or ASP.NET Core. For more information and instructions, see IIS 8.0 Using ASP.NET 3.5 and ASP.NET 4.5 or Host ASP.NET Core on Windows with IIS.
- Make sure the app runs on IIS without errors.
Besides, to debug app with local IIS, please refer to
this article to modify preconfigured settings.

With Regards,
Fei Han
