ODP.NET

This is a cross-post from https://community.oracle.com/tech/developers/discussion/4490184/unexpected-exception-when-reconnecting-to-database-after-init-without-connection-to-db, because I think it was posted in the wrong forum.
Hi,
I discovered an issue when using an Easy Connect connectionstring that doesn't occur when using a TNS less connectionstring.
The usecase is the following:
Create a little test project containing a single API call that fetches some records from the Oracle database via EF Core (standard ASP.NET and EF Core example code).
Then do the following to get the exception:
If is unplug the network and disable the wifi so that no connection can be made to the Oracle Database
Start the API project (hosted in IIS Express)
Via Swagger or Postman call the API => this will give an exception (completely normal behavior)
Plug the network back in and/or enable to wifi so the database is accessible again
Via Swagger or Postman call the API again => this and every other call keeps returning the same exception
If the connectionstring is switched from Easy Connect to TNS less, the second call doesn't give an exception but returns the expected result.
This is the stacktrace:

Oracle.ManagedDataAccess.Client.OracleException (0x80004005): ORA-12154: TNS:could not resolve the connect identifier specified

Example connectionstrings:
Easy Connect

Data Source=server.industry.net/database;User Id=dataUser;Password=dataPassword

TNS Less

Data Source=(DESCRIPTION=(ADDRESS_LIST=(ADDRESS=(PROTOCOL=TCP)(HOST=server.industry.net)(PORT=1521)))(CONNECT_DATA=(SERVICE_NAME=database)));User Id=dataUser;Password=dataPassword;

This is probably a bug in the Oracle.ManagedDataAccess.Client?
Kind regards,
