No need for the nested try-finally blocks.
Without them, you can easily introduce bugs where resources don't get cleaned up.

For example:
SqlConnection connection = new SqlConnection("...");
SqlCommand command = new SqlCommand("...", connection);
try
{
   ...
}
finally
{
    if (command != null) ((IDisposable)command).Dispose();
    if (connection != null) ((IDisposable)connection).Dispose();
}
If the SqlCommand ctor throws an exception, the SqlConnection is never cleaned up.

To do it properly, you would need something like:
SqlConnection connection = null;
SqlCommand command = null;
try
{
    connection = new SqlConnection("...");
    command = new SqlCommand("...", connection);
    ...
}
finally
{
    if (command != null) ((IDisposable)command).Dispose();
    if (connection != null) ((IDisposable)connection).Dispose();
}
It's quite a lot of boilerplate and ceremony that the developer needs to get just right to make it work as well as a couple of using blocks.
