I have been screwing around with .NET Core 1.0.1. I am just trying to get a Hello World page up and running. During the build, I ran into the following error:
The type or namespace name 'Web' does not exist in the namespace 'System' (are you missing an assembly reference?)
I tried adding the reference to my project.json:
"dependencies": {
"Microsoft.NETCore.App": {
"version": "1.0.1",
"type": "platform"
},
"Microsoft.AspNetCore.Mvc": "1.0.1",
"Microsoft.AspNetCore.Routing": "1.0.1",
"Microsoft.AspNetCore.Server.IISIntegration": "1.0.0",
"Microsoft.AspNetCore.Server.Kestrel": "1.0.1",
"Microsoft.Extensions.Configuration.EnvironmentVariables": "1.0.0",
"Microsoft.Extensions.Configuration.FileExtensions": "1.0.0",
"Microsoft.Extensions.Configuration.Json": "1.0.0",
"Microsoft.Extensions.Logging": "1.0.0",
"Microsoft.Extensions.Logging.Console": "1.0.0",
"Microsoft.Extensions.Logging.Debug": "1.0.0",
"Microsoft.Extensions.Options.ConfigurationExtensions": "1.0.0",
"Microsoft.AspNetCore.StaticFiles": "1.0.0",
"System.Web": "4.0.0" //Right here
}
But I get the error: The dependency System.Web >= 4.0.0 could not be resolved
. It does not appear I can add the reference normally as in a C# console/dll library.
Is there another package I need to install that actually contains the system.web assembly? Or is there a way to manually add this reference?

In .NET Core, and specifically ASP.NET Core, there is no System.Web anymore. All ASP.NET components live in the Microsoft.AspNetCore.*
and Microsoft.Extensions.*
namespaces.
For example, HttpContext
lives in Microsoft.AspNetCore.Http
and Controller
in Microsoft.AspNetCore.Mvc
.
I suggest you read into the fundamentals of ASP.NET Core.
