everything work fine locally but on the web i have an exception 

System.Data.Entity.Core.EntityException: The underlying provider failed on Open. ---> FirebirdSql.Data.FirebirdClient.FbException: Can't create directory "C:\ProgramData\firebird\". OS errno is 5 ---> FirebirdSql.Data.Common.IscException: Can't create directory "C:\ProgramData\firebird\". OS errno is 5

- copy also firebird config file in and change the root variable to absolue Bin path

- copy my database to app_data folder

i build my connectionstring dynamically like this


   string p = "metadata=res://*/MyFBEmbedModel.csdl|res://*/MyFBEmbedModel.ssdl|res://*/MyFBEmbedModel.msl;provider=FirebirdSql.Data.FirebirdClient;provider connection string='client library=??fbembed??;initial catalog=|DataDirectory|D2015.gdb;user id=sysdba;password=masterkey;Connection lifetime = 0; Pooling = true; MinPoolSize = 0; MaxPoolSize = 500; Packet Size = 8192; ServerType = 1'";

            string mslinepath = HttpContext.Current.Server.MapPath("Default.aspx");

            mslinepath = Path.GetDirectoryName(mslinepath);

            p = p.Replace("??fbembed??", mslinepath + @"\Bin\fbembed.dll");

            context = new MyFBEntities(p);
