ADO.NET Error
Hi everyone, I'm running into an issue when trying to add an ADO.NET Entity Data Model in Visual Studio 2022.
I get a
System.Data.Entity.Core.EntityException with the inner exception saying: "An attempt to attach an auto-named database for file ... failed. A database with the same name exists..."
It seems VS is looking for the .mdf file inside the VS Installation folder (Common7\IDE) instead of my project folder.
Has anyone faced this pathing issue before? Is this related to a bad connection string in Web.config or a LocalDB instance conflict? Any help is appreciated!

i see, so basically what I should do to learn the new thing is create the ASP.NET Core Web App (MVC) and follow the newest tutorial right?

So to clarify, I learn this for my internship on december which the company told me that they're using ASP.NET for their projects. This's what I should learn right?
also do u have a recommended tutorial for me on starting learning on ASP.NET environment?
since my background is on golang backend development, and this visual studio is a whole new thing for me

im afraid no, the company only told me like they use Vue as their frontend and ASP.NET as their backend
but no further information regarding what dotnet they're using
