problem with connection string

Мария Графова

Hi, i have problem with my win form entity framework based application. When i run program everything is ok but when i create and install setup have problem. I start application and receive error message:
No connection string named "PhonebookEntities" could be found in the application config file

I use SQL Server 2012 with server name: NT2\SQLEXPRESS1 and DBcontext name= PhonebookEntities

<add name="PhonebookEntities" connectionString="metadata=res://*/PhoneModel.csdl|res://*/PhoneModel.ssdl|res://*/PhoneModel.msl;provider=System.Data.SqlClient;provider connection string="data source=NT2\SQLEXPRESS1;initial catalog=Phonebook;integrated security=True;MultipleActiveResultSets=True;App=EntityFramework"" providerName="System.Data.EntityClient" />

I think you have created and deleted connection string many times thats why this type of error is coming.
just remove all connection string and get from server explorer.=>right click=>connection string
