From Solution Explorer, open the appsettings.json file and add the following (new lines highlighted):
{
"ConnectionStrings": {
"DefaultConnection": "Data Source=(localdb)\MSSQLLocalDB;Initial
Catalog=TestMakerFree;Integrated Security=True;
MultipleActiveResultSets=True"
},
"Logging": {
"IncludeScopes": false,
"Debug": {
"LogLevel": {
"Default": "Warning"
}
},
[...]
This is the connection string we’ll be referencing in our project's Startup.cs file later on.
