问题
Are there any caveats or short comings to using the new Task API in System.Threading.Task in ASP.NET hosted under IIS?
I know prior to .NET 4.0 working with any of the ThreadPool actions inside of IIS was always recommended to be avoided.
回答1:
Any caveats to using ThreadPool with IIS would still be valid using System.Threading.Task, as the Task API is just an additional layer of abstraction over System.Threading.
For long-running tasks in the background, I use a ThreadPool inside a Windows Service. This keeps it outside of IIS.
