Answer 1

Add a reference to System.Web.dll to your project. If your project will be running on computers with the ".NET Client Profile" then you just need to ensure a copy of System.Web.dll is bundled with your application.

Answer 2

".NETFramework,Version=v4.0,Profile=Client" means "Client profile", which means that only a subset of the .net will available to your app. System.Web.* assemblies are not part of that subset. The compiler is complaining because you have a reference to an assembly that is not part of the Client Profile and is not referenced by your project, so it cannot resolve the assembly location. You must include a reference to the referred assembly and change the property "Copy local" to "true" (Click on assembly reference then F4). This will cause the assembly to be copied into the "/bin" folder of the current project. You must also deploy this assembly with your project because it will not be available on the client machine.
