how to override local connection string with azure connection string (1 answer)

Closed last year.

I have written connection string in appsettings.json for .Net core project. My connection string is :

 "ConnectionStrings": {
"OT_DB_Connection": "Data Source=108.***.**.**;Initial Catalog=O*******s;User ID=O*******s;Password=O*********$"

},

I am accessing this connection string in startup.cs file as shown below.

options.UseSqlServer(Configuration.GetConnectionString("OT_DB_Connection"));

Now i deployed this website on azure and i have separate database on azure and i want that my website will to connect to azure database at runtime by overriding the local connection string.

Please suggest how i can achieve this.

Thanks

You may create application setting entry (in Azure) with name ConnectionStrings:OT_DB_Connection and read it as

Configuration["ConnectionStrings:OT_DB_Connection"]

This code will read both and you appsettings value for local development, and overrided value in Azure App Service.
