.NET Deployment to Azure

Question

So I've finally deployed to Azure, I've got my application live though its not passing my databases over and i get the error at the bottom.

I use Local DB and have SQL Server express installed. How do i publish my database to Azure with it? I've changed my datasource connection string to something generic:

Data Source=(LocalDB)\v11.0;AttachDbFilename=|DataDirectory|\Database.mdf;Integrated Security=True

I found a post about SQL Server compact, is this the best way?

I use code first migrations which I read is easiest just really need some direction on what is best as I'm clueless!

Based on your question and the comments, I believe you published you application to an Azure PaaS solution. The issue you are running into is Azure App Services do not let you use LocalDB. You will need to use Azure SQL Databases for your application. Without knowing more about how you created and use your database, I can't say for certain what will be the best way to fix your problem. You may need to use a SQL Server database project and DACPAC to deploy your database or you may simply need to provision an Azure SQL Database and grant your App Services access to it.

Below are links that should help get you pointed in the right direction.
