EF 无法找到生产数据库

Question

Info

Project is ASP.NET Core 5.0, ORM is EF, DB is SQL Server

Problem

On Development, our database is accessible but on production its not!

Connection String

Is set in appsettings.json and its:

"MyConnectionString": "Data Source=MyDomain.com;Initial Catalog=MyDB;Persist Security Info=True;User ID=USERNAME;Password=PASSWORD"

When we run the project in Visual Studio with this connection string, everything is fine, but it fails when it's published to the host.

The error is:

A network-related or instance-specific error occurred while establishing a connection to SQL Server. The server was not found or was not accessible. Verify that the instance name is correct and that SQL Server is configured to allow remote connections. (provider: Named Pipes Provider, error: 40 - Could not open a connection to SQL Server)

Any suggestions?

Thanks in advance.

Answer 1

Certainly not in the production environment. Asha, did you enter the string connection in the appsetting file in the Development section? Or in the production section
