Entities' does not contain a constructor that takes 1 arguments

        return ConfigurationManager.ConnectionStrings[\"DCAssetEntities\"].ConnectionString;
            


        

Answer 1

Make the constructor yourself in a partial class:

public partial class DCAssetEntities: DbContext
{
    public DCAssetEntities(string connectionstring)
        : base(connectionstring)
    {
    }
}
