Does Visual Studio 2017 Community (.NET Framework 4.6.2) support Oracle 8i Does Visual Studio 2017 Community (.NET Framework 4.6.2) support Oracle 8i?

I am trying to connect with .NET Framework 4.6.2 to a production Oracle 8i database. 

I googled it, but I can not find anything which is related to this topic. 
I checked also this site but that is for Windows 2008 R2.

I tried Oracle 19 and Oracle 18 and it works. But I can't find what the oldest version is that is still compatible with .NET Framework (like Oracle 8 or Oracle 9) .

I tried to connect using ODP.NET Managed Driver but it was unsuccessful.

I am an Oracle Developer and Web Developer for the organisation. I have been given the task to test it if it's possible to connect on our  (TEST) database which is Oracle 8i (I believe). Our main database is Oracle 10, but this data is restricted and I cannot manipulate it. This part is for our DBA.
I don't have an 8i database handy to test. If you care about your data it'd be wise to upgrade to a supported version of Oracle ASAP. The last version of Oracle client that can connect to Oracle 8i is an Oracle 10 client (and you need to be on Oracle 8.1.7 server-side).

If you can find an Oracle 10 client install (either full-fat or the instant client), then you might be able to get it to work. - Phil

The article referenced in the question is rather bad. Listed prerequisites are wrong/outdated (was even in 2015), it does not properly use the tnsnames.ora file, and does not consider 32/64-Bit topic.

See my answer to Does ASP.NET MVC5 support Oracle 8i on Stack Overflow. - wernfried-domscheit
