问题 I have a problem with the async file uploading feature of WebApi. Currently I am able to save the file using the provider, but I then want to use a service (_myService) to log the filename of the file uploaded. Inside the service, it uses another service to get the current UserId. It does this by using the current HttpContext. Unfortunately the current HttpContext seems to be lost within the new task thread. I tried to add TaskScheduler.FromCurrentSynchronizationContext() as the 2nd parameter

问题 I’ve created an WebAPI sql interface so that development users can dynamically query a database through a RESTful interface. It’s fast for small queries but when larger ones come into play there are serious lag problems especially when multiple simultaneous calls are made. I’ve run performance analysis on this and overwhelming majority of the processing is done on the line: var xe = reader.ReadOuterXml(); The clients are expecting XML text strings so I’ve tried to just do an ExecuteReader but
