c# - Error in update-database command in code first migration

Question

I am working on Desktop application in WPF and creating SqlRepository with LocalDB to store data. I am using following tools

• Visual Studio 2013 Community with update 2
• Entity Framework 6.1.2 for Code first migration

I have created local database with Microsoft SQL Server Database File (SqlClient) configuration. Database created successfully and below is connection string fetched from Sql

Data Source=(LocalDB)v11.0;Initial Catalog=D:USERSUSERNAMEDOCUMENTSTestDatabaseestdb.MDF;Integrated Security=True;Connect Timeout=30;Encrypt=False;TrustServerCertificate=False

I am using same connection string in app.config. I can view database object in SQL Server Database explorer in Visual Studio. But when run update-database command in Nuget package manager console, I am getting below error:

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: SQL Network Interfaces, error: 26 - Error Locating Server/Instance Specified)

Answer 1

I had similar problem and fixed it when I changed the "start-up project" from another module to the module containing references to all other projects in the solution. Right-click module >> click "Set as StartUp Project"
