Oracle Kerberos support for .Net 5.0

I am trying to check if I am connect to Oracle using .Net 5.0 and Kerberos based on the closed github issue here.

I am using Oracle.ManagedDataAccess.Core, Version 3.21.1 library to connect to the oracle database using Kerberos but I am getting a Could not load file or assembly 'Oracle ManagedDataAccessIOP, Version=3.1.21.1 error.

What could I missing? The connection succeeds, if I do not connect to the database using Kerberos(i.e I comment out all the lines in the sqlnet.ora file)

static void Main(string[] args)
{
OracleConnection oracleConnection =
new OracleConnection("User Id=<DatabaseName>; Password=<Password>; Data Source=(DESCRIPTION = (ADDRESS = (PROTOCOL = TCP) (HOST = <Host>) (PORT =6136)) (LOAD_BALANCE=yes) (CONNECT_DATA=(SERVER = DEDICATED) (SERVICE_NAME=<ServiceName>)))");
oracleConnection.Open();    
}

sqlnet.ora

sqlnet.authentication services=(Kerberos5)
sqlnet.kerberos5_conf=I:\.NET Core 5 Kerberos Example\krb5\krb5.conf
sqlnet.kerberos5_cc_name=I:\.NET Core 5 Kerberos Example\krb5\krb5cc_cce_app_kd
