system.web

I updated .NET from 3.5 to 4.0 version, but after updating the assembly System.Web doesn't work any more. I'm getting the following error: Warning 1 Could not resolve assembly "System.Web". The assembly is not in the currently targeted framework ".NETFramework,Version=v4.0,Profile=Client". Please remove references to assemblies not in the targeted framework or consider retargeting your project. Using the 3.5 version it works fine. How can I fix this?

I have a string that I'd like to encode into the standard URL format. From what I've found, I should be able to do this via the httpUtility.urlEncode method, but I don't seem to have that available. I've added "using" references to both System.Web and System.Net to no avail. I've also seen other references to server.urlEncode amongst other variants, but I don't see the method anywhere. I'm using the latest version of C# in Visual Studio 2010. Is the method called something different in this version, hidden somewhere else, or am I completely off base? By default, new projects in Visual Studio

Is there an alternative way to get the Windows Username for when the dll is running in ASP.NET which won't use System.Web. The only way I can currently see to avoid System.Web is to pass the Username as a

I'm working on a project in C#.Net 4.0. I am trying to use HttpUtility.HtmlDecode. To do so, I added using System.Web; to the top of the file. However, no reference to HttpUtility could be found. After Googling around a little bit I found that the common answer to this question was to add a reference to System.Web.dll by finding it in the list presented by right-clicking on References in the Solution Explorer and clicking "Add Reference...". Unfortunately, this was not in the list. I found System.Web.Services and System.Web.ApplicationServices, but no System.Web, and neither contained what we
