    Is the System.Web.dll library connected to the project? Judging by the signs - no. - kodv
  • Exactly, however, I noticed that mscorlib is also not connected, but in the project using System.Collections.Generic there are classes of generalized collections available, how so? - BlackOverlord

Classes of their single namespace can be defined in different assemblies (different DLLs).

System.Web.AspNetHostingPermission and the remaining two classes from the prepress are defined in System.dll , which is connected to the default project.

The remaining classes from System.Web defined in System.Web.dll , which you need to add in the project References - select the project in Solution Explorer, right-click on References, Add Reference.

    Try

     using System.Web; using System.Web.Mail; // к примеру

    Or if you know what you need, then write it, and the studio itself will offer what you need to add to using.
