Updating EF String connection C#

I have a vs installer which updates the connection string of Entity Framework in the app config. Using XmlDocument.

This is the code:

 attribute.Value = "metadata=res://*/Veterinaria.csdl|res://*/Veterinaria.ssdl|res://*/Veterinaria.msl;provider=System.Data.SqlClient;provider connection string=&quot;data source=" + Context.Parameters["InstanciaSQL"] + ";initial catalog=Sistema_Veterinaria;integrated security=True;MultipleActiveResultSets=True;App=EntityFramework&quot;";

The problem is that in the xml instead of writing "string="data source=", it writes "string="data source"

It seems an encoding problem. Already tryed &&,&amp,", with no luck.

Use + for concatenation in your code and try that way.
