Hello,

FirebirdSql.EntityFrameworkCore.Firebird 11.0.0 FirebirdSql.Data.FirebirdClient 10.3.1 Entity framework 8.0.4 firebird db 3.0

I run command:

dotnet ef dbcontext scaffold "User=SYSDBA;Password=***;Database=\tt\tt\tt\tt.fdb;DataSource=localhost;Port=3050;Dialect=3;Charset=UTF8;Role=;Connection lifetime=15;Pooling=true;MinPoolSize=0;MaxPoolSize=50;Packet Size=8192;ServerType=0;" FirebirdSql.EntityFrameworkCore.Firebird --output-dir Models --context TTDbContext --context-dir DataContext --force

it hangs for some time, but fails with error
