How to visualize SQL Server database made from ASP.NET Core Web API with DBVisualizer

Question

I'm a beginner in ASP.NET Core, SQL and DBVisualizer (in web programming in general).

I would like to visualize my database with DBVisualizer but I get an error :

An error occurred while establishing the connection:

Long Message:
Failed to connect TCP/IP to host localhost, port 5041. Error: “The driver received an unexpected preconnect response.
Review the connection properties and verify that an instance of SQL Server is running on the host and accepting TCP/IP connections to the port. This driver can only be used with SQL Server 2005 or later.
ClientConnectionId:41197c49-49ad-4191-8bdc-0dd7905eaede

FYI I translated everything after Long Message: from French to English.

In Program.cs, I create the DB context like that :

builder.Services.AddDbContext<ApplicationDbContext>(options => options.UseSqlServer(builder.Configuration.GetConnectionString("DefaultConnection")));

My connection string in appsettings.json is :

"ConnectionStrings": {
    "DefaultConnection": "Data Source=(localdb)\\MSSQLLocalDB;Initial Catalog=RestoCommandDB;Integrated Security=True;ApplicationIntent=ReadWrite;MultiSubnetFailover=False"
  },

Then on DBVisualizer side, I configure my connection like that :

I have no userId or password that I know of. The ping works.

Thanks for your help
