Does this support in-memory database?

I got SQLite.SQLiteException when I tried var db = new SQLiteConnection("Data Source=:memory:");

The work around:

       public const SQLite.SQLiteOpenFlags DefaultFlags =
                    // open the database in memory
                    (SQLiteOpenFlags)0x00000080 | 
                    // open the database in read/write mode
                    SQLite.SQLiteOpenFlags.ReadWrite |
                    // create the database if it doesn't exist
                    SQLite.SQLiteOpenFlags.Create |
                    // enable multi-threaded database access
                    SQLite.SQLiteOpenFlags.SharedCache;

Is it possible to open multiple connections to an in-memory DB? According to https://www.sqlite.org/inmemorydb.html, the connection string should be either "file::memory:?cache=shared" for a single in-memory database or "file:memdb1?mode=memory&cache=shared" for one or more named in-memory databases.

However, the first throws an exception:

SQLiteException: Could not open database file: file::memory:?cache=shared (CannotOpen)

and the second creates a file-based db in a file called file. This is apparently taken from the URI, because it creates a file called foo if I change it to "foo:memdb1?mode=memory&cache=shared".
