What is wrong with the connection string?

[Suman Gurung]

"ConnectionStrings": {
   "Defaultconnection": "Server = (localdb)\\mssqllocaldb;Database=QualitySouvenir;Trusted_Connection=True;MultipleActiveResultSets=true"
 },
What's wrong with this string? I am not able to add controller.

What do you mean? What are you trying to achieve and what is happening?

I am trying to add a controller but it is showing this error in the connection string. Any fix for this.

Controllers don't have anything to do with connection strings. What exactly do you mean by "adding a controller"? Do you mean adding a new controller to the project? What steps are you performing to do this?

I tried to do it through Scaffolding process but error shows in the connection string. Any solution to it.

What scaffolding option are you using? And where does the connection string appear?
