We're building high performance database applications, and are trying to use
all the new Async ADO.Net 2.0 features.

The problem we're having is that we can't find a
SqlConnection.BeginOpen/EndOpen method. We can execute everything using the
BeginExecuteCommand, but without the BeginOpen on the connection we end up
with lots of deadlocked threads, all waiting for SqlConnection.Open. This
means things are more-or-less useless.

We looked briefly into MARS for doing this, as that might be an option, but
we really prefer the more standard Async stuff as it maps much easier into
working with other database providers such as Oracle.

What's frustrating is that early Whidbey builds, and many old ADO.Net 2.0
articles, refer to these methods so they existed at one point. These methods
were obviously removed during the .NET 2.0 RTM process, which seems really
strange.

Any ideas how to work around this and actually do highly scalable I/O using
the Async infrastructure in ADO.NET 2.0?
