Working in MVC 5 Identity for email verification

问题

private IAuthenticationManager AuthenticationManager { get { return HttpContext.GetOwinContext().Authentication; } }

I get the error : 'System.Web.HttpContextBase' does not contain a definition for 'GetOwinContext' and no extension method 'GetOwinContext' accepting a first argument of type 'System.Web.HttpContextBase' could be found (are you missing a using directive or an assembly reference?) What might be wrong?

回答1:

It seems you have missing NuGet package called 'Microsoft.Owin.Host.SystemWeb'. Install package from NuGet or use package manager console to install the package.

Install-Package Microsoft.Owin.Host.SystemWeb

Hope this helps.
