Can someone please tell me what is the error
In my case, I created a new project and when I ran it the first time, it gave me the following error:
An unhandled exception was generated during the execution of the current web request. Information regarding the origin and location of the exception can be identified using the exception stack trace below.
So my solution was to go to the Package Manager Console inside the Visual Studio and run:Update-Package
Problem solved!!
As far as I understand, you have more than one form tag in your web page that causes the problem. Make sure you have only one server-side form tag for each page.
