2017.2 OSX, trouble with .NET libs

I'm trying to get a few things to work with .NET 4.6, namely Mono.Data.Sqlite.SqliteConnection and System.Net.WebClient, I definitely need those two things. Where should I be copying the proper libraries from?

On OSX Standalone with a SqliteConnection as soon as I do an Open() with a connection string I get an error that says you can't have any other DataReaders open. There's no other connections, no other scripts using SqliteConnection, no other DataReaders/Commands. Also it works fine on the Editor, just not standalone.

Code (csharp):

1.  
2.         Mono.Data.Sqlite.SqliteConnection conn = new SqliteConnection(connectionString);
3.         conn.Open();
4.         var cmd = conn.CreateCommand();
5.         cmd.Dispose();
6.         conn.Close();
7.         conn.Dispose();
8.  
9. Cannot set CommandText while a DataReader is active

On WebClient http requests work, but https tells me it can't find Security. The workaround is using WWW, but doing Coroutines when you have several web requests is a lot more code overhead than just using an await with WebClient. I just need to know exactly what to include.

Code (csharp):

1.  
2.         WebClient wc = new WebClient();
3.         byte [] blah = wc.DownloadData(@"https://www.anyhttpssite.com");
