firebird-embedded

I have been writing a small Python app for several weeks. The application reads data from a Firebird database and it copies it to another DB. I'm using FDB with Firebird embedded. This is my connection code. def createConnectionTo(path): try: connection = fdb.connect( database=path, user='SYSDBA', password='masterkey', charset='WIN1252' ) print("Connessione al database riuscita!\n") return connection except fdb.fbcore.DatabaseError as details: errorMsg = "ERRORE: impossibile connettersi al database!\nPer favore scegliere un altro file.\n\nDETTAGLI\n"+str(details).replace("\\n", "\n")+"\n"

I am trying to connect to Firebird 3 embedded database from a .NET project. I have copied all the files of Firebird to the executing directory of the application. I have used the following connection string builder: var builder = new FbConnectionStringBuilder() { UserID = v1, Password = v2, Database = v3, ServerType = FbServerType.Embedded, Charset = "UTF8", ClientLibrary = "fbclient.dll" }; However I get the following connection error FirebirdSql.Data.FirebirdClient.FbException (0x80004005): Unable to complete network request to host "xnet://Global\FIREBIRD". Unable to complete network

I'm using an embedded Firebird database with code first (Entity Framework 6). The first time the application runs, it works fine: the database gets created and the data gets inserted. But every time it runs after that, it throws the following exception: An exception of type 'System.NotSupportedException' occurred in FirebirdSql.Data.FirebirdClient.dll but was not handled in user code Additional information: Unknown data type The project includes the following NuGet packages: EntityFramework [6.0.2] Firebird ADO.NET Data provider (Entity Framework 6) [4.1.0.0] I added the DbProviderFactories
