Have you seen https://ncalc.codeplex.com/ and https://github.com/sheetsync/NCalc ? It’s extensible, fast (e.g. has its own cache) enables you to provide custom functions and varaibles at run time by handling EvaluateFunction/EvaluateParameter events. Example expressions it can parse: Expression e = new Expression(“Round(Pow(Pi, 2) + Pow([Pi2], 2) + X, 2)”); e.Parameters[“Pi2”] = new Expression(“Pi * Pi”); e.Parameters[“X”] = … Read more
You cannot use Visual Studio 2008 to develop 4.0 applications in a supported manner. Currently only Visual Studio 2010 can be used to develop 4.0 apps. Starting with 2008 you can use it to develop for earlier versions of the framework but not later ones.

If you added it later, you should delete it. OR May be Somehow a precompiled.config file has made it to production. Deleting that file should resolve the App_Code directory error.
Of course: ASP.NET has a built-in control called Panel! And you may use it as follows: <asp:Panel ID=”myPanel” runat=”server”> <!– Other markup here like client and server controls/elements –> </asp:Panel> It’s a container, so you add Controls to it in the code-behind like: myPanel.Controls.Add(new LiteralControl(“Hello World”)); You can add the Literal control (or any others) … Read more
Sometimes you still need to know if Cookie exists in Response. Then you can check if cookie key exists: HttpContext.Current.Response.Cookies.AllKeys.Contains(“myCookie”) More info can be found here. In my case I had to modify Response Cookie in Application_EndRequest method in Global.asax. If Cookie doesn’t exist I don’t touch it: string name = “myCookie”; HttpContext context = … Read more
