I am starting a job at a new company and i'm supposed to start using a system developed in .net core MVC by someone else.



I have a local copy of the database and a local copy of the code.
I can acces the SQL server DataBase and make my own SQL requests in SQL Server 2014, unfortunatly i cannot connect my Visual Studio code to my database and make everything work locally.



I tryed to load "ViewsHomeIndex.cshtml", the page starts to load at "localhost:45896" and after a few seconds i get the bellow error:



It appears the path is not properly written in the json file, but i am not sure how to write it any other way.



Or maybe something else.



Connection String:




"ConnectionStrings": {
"DefaultConnection": "Server=/SQLExpress;Database=something_article;User
Id=admins;Password=Admin;",
"EntityFrameworkConnection": "data source=172.16.10.5;initial catalog=companyname_common;persist security info=True;user
id=admin;password=azerty;MultipleActiveResultSets=True;App=EntityFramework""
},




Thank you

  • Maybe you can take a look in your MVC application at a file called Web.config and locate the <connectionStrings> and make sure it points to your localdb?

  • My web.config file has no "ConnectionString" in it. :(
