Hi programming,
Programming and Design
The type or namespace name 'Http' does not exist in the namespace 'System.Web'
If you want to get System.Web.Http, you need to install package - Microsoft.AspNet.WebApi.Core from Nuget.
More information about Microsoft. AspNet. WebApi. Core you can refer to this link: Microsoft.AspNet.WebApi.Core
But asp.net core does not include aspx pages.
Best regards,
Sam
