I downloaded Firebird-1.5.6.5026-0_embed_win32.zip and copy the file fbembed.dll and firebird.msg and ib_util.dll near my Program. and i use this connection string :
<add name="Connection" connectionString="server type=Embedded;user=SYSDBA;password=masterkey;database=E:\TEST.FDB;dialect=3;charset=NONE;connection lifetime=15;pooling=true;minpoolsize=0;maxpoolsize=50;packet size=8192;servertype=0;clientlibrary=fbembed.dll" providerName="FirebirdSql.Data.FirebirdClient" />
