Well, I know there was some topic about that, but believe me - i tried everything and still didn't get answer how to solve that issue.
Error: The specified named connection is either not found in the configuration, not intended to be used with the EntityClient provider, or not valid.
In app.config i have connection string:
<add name="GetProductsEntities" connectionString="metadata=res://*/GetProductsModel.csdl|res://*/GetProductsModel.ssdl|res://*/GetProductsModel.msl;provider=System.Data.SqlClient;provider connection string="data source=(local);initial catalog=mainDB;integrated security=True;multipleactiveresultsets=True;App=EntityFramework"" providerName="System.Data.EntityClient" />
samae as in my model when I click properties:
metadata=res://*/GetProductsModel.csdl|res://*/GetProductsModel.ssdl|res://*/GetProductsModel.msl;provider=System.Data.SqlClient;provider connection string="data source=(local);initial catalog=mainDB;integrated security=True;multipleactiveresultsets=True;App=EntityFramework"
In my PC everything works great. But when I copy executable file to my friend PC, im having those errors:

At this momment my Model is in the same folder as app.config. I tried to copy connectionString directly into
public GetProductsEntities() : base("name=GetProductsEntities", "GetProductsEntities")
but still have errors that Data source is not proper value for connection string etc..
Help me, please.
Thanks!
