System.Data.SQLite

I am trying to build a Windows Shell ThumbnailHandler. I have a sqlite3 file in which I store a thumbnail in a particular table.

https://msdn.microsoft.com/en-us/library/windows/desktop/bb774614(v=vs.85).aspx

For security reasons Windows only provides a stream to the file, not the file name and path. I am currently copying the stream to a temporary file, then opening that file with sqlite. This is an unsustainable solution, however, as these files will be accessed over the network and can be up to gigabytes in size.

As I unable to open the file directly, I need to be able to open a connection using the provided stream or come up with something more clever (and dangerous...). A brief look at the file format doesn't indicate that there is any provision for user data in the file as (presumably) the response to such a request would be "just store it in the database, crazy".

Do the oracles at system.data.sqlite.org have any suggestions?

There is currently no way to open a SQLite database from a managed stream.
