ASP.Net MVC Long Running Process

Question

I have a requirement to produce a report screen for different financial periods. As this is quite a large data set with a lot of rules the process could take a long time to run

Answer 1

In case your app is running on Windows Server with IIS your ASP.Net code can create a record in db table which will mean that report should be created.

Then you can use Windows Service or Console App which might be running on the same server and constantly checking if there any new fields in the table. This Service would create a report and during creation it should update table field to indicate progress. Your ASP.net page might be displaying progress bar, getting progress indication from db using ajax requests or simply refreshing the page every several seconds.

If you are running on Windows Azure cloud you might use WebWorker instead of Windows Service

For screen locking on your page you may use jquery Block-UI library
