           Summary: Missing method
                    nsaction) when using a .NET 2.0 library and compiling

When running a program that was compiled with dmcs and uses a .NET 2.0 library
(SQLite or MySql ADO.NET provider), I get a missing method exception in
System.Data. If the program is compiled with gmcs instead or uses the class
with the missing method directly, no exception is thrown.

Reproducible: Always

Steps to Reproduce:
1. Copy System.Data.SQLite.dll to working directory (attached)
2. Create test.cs with the following code:
/* code starts */
using System.Data.SQLite;

class Program
        static void Main()
                var connectionString = "Data Source=:memory:;Version=3";

                var connection = new SQLiteConnection(connectionString);

                var command = new SQLiteCommand("CREATE TABLE Test(t int)",
/* code ends */
3. dmcs -r:System.Data.SQLite.dll test.cs
4. mono test.exe
5. Notice the exception
6. gmcs -r:System.Data.SQLite.dll test.cs
7. mono test.exe
8. Notice that there is no exception

Actual Results:  
The following exception is thrown when compiled with dmcs and run:

Missing method System.Data.Common.DbConnection::EnlistTransaction(Transaction)
in assembly
referenced in assembly /tmp/bug2/System.Data.SQLite.dll

Unhandled Exception: System.MissingMethodException: Method not found:
  at Program.Main () [0x00000] in <filename unknown>:0

Expected Results:  
No exception is thrown

I've looked at 2.0 and 4.0 versions of Mono's System.Data.dll with Reflector
and method is present in both versions.

As noted above, no exception is thrown if program is compiled with gmcs and/or
NET 2.0 library is not used.

Mono.Data.Sqlite.dll could be used instead of System.Data.SQLite.dll, but the
same exception is also thrown when using mysql.data.dll and SQLite is easier to
reproduce (does not require a database server).
