By default Sharepoint does not allow server-side code to be executed in ASPX files. See this for how to resolve that. However, I would raise that having a code-behind is not necessarily difficult to deploy in Sharepoint (we do it extensively) – just compile your code-behind classes into an assembly and deploy it using a … Read more
