Make your VS to more verbose to find out errors in details to do so: Tools → Options then Project and Solutions → Build and Run section. You have a combo box for verbosity. then you may find valid excpetion, could be due to VS admin issue as well.

Hi Jignesh, I don't have Administrator access to my system. I am using with normal user privileges. To open Visual Sudio `Run as Administrator` is it mandatory?

Check the configuraion from configuraion manager of build menu If it is Release try to select Debug from the combobox 1=Right click on the project click on properties. 2=check startup path and debug ect ... Thanks and Regards

In project properties->web->debuggers, native debugger was checked. After unchecking that and building the project, the application was able to debug, hitting the break points. https://docs.microsoft.com/en-us/visualstudio/debugger/troubleshooting-breakpoints?view=vs-2019 https://www.c-sharpcorner.com/UploadFile/7078b8/breakpoints-are-not-working-in-visual-studio/#:~:text=Solution%3A%20Disable%20the%20%22Just%20My,Visual%20Studio%20as%20an%20administrator.&text=Go%20to%20Debug%20from%20the%20menu%20bar.&text=Now%20select%20the%20option%20Automatically,and%20click%20the%20OK%20button.
