Is there any danger in using ConfigureAwait(false) in WebApi or MVC controllers?

Question

Say I have two scenarios:

1) WebApi Controller

    [System.Web.Http.HttpPost]
    [System.Web.Http.AllowAnonymous]
    [Route(\"api/regi         


        

Answer 1

You may use ConfigureAwait on public action MVC Controller, it help to prevent deal lock if your _userService.GetAuthViewModelAsync keeps waiting. it cloud raise deadlock if async service keeps await so by may block httpcontext of UI.

Have look below link to understand this case:
