Publishing ASP.NET MVC to Azure

Before we dive into the specifics of SQLite data fetching, let's first discuss how to publish an ASP.NET MVC application to Azure. Here are the steps:

  1. Create an Azure account and set up a web app in the Azure .
  2. In Studio, right-click on your ASP.NET MVC project and select “Publish”.

Ensure that the connection string for your SQLite database is correctly configured in your ASP.NET MVC application. The connection string should include the server name, database name, and authentication .


// Example SQLite connection string
string connectionString = "Data Source=mydatabase.db;Version=3;";
