How to create a long running background task from MVC
asp.net-mvc async-await c# entity-framework multithreading
Question
I am using EF6, MVC 5 in VS 2013.I have a long running task which is causing timeout errors and so I want to set it running as a separate background task and return immediately to the web controller. The background task will report progress to an SQL server database. What I need, essentially, is fire and forget functionality. There appear to be a number of options:
- Write the tasks details to a server and use a Windows service to process them UPDATE: this was the options used
- Use
async- this does not seem to be a safe option - Use HostingEnvironment.QueueBackgroundWorkItem Method
Option 3 would be preferred as it keeps all the code in one solution. Please could you comment on the pros and cons of each and point, if possible, to worked examples of number 3.
Accepted Answer
HostingEnvironment.QueueBackgroundWorkItem is a valid solution, but keep in mind that the long running process may be interrupted, for example if application pool recycles.
A better option would be to run it in a scheduled task, for example using Quartz.NET.
