Missing a using directive or an assembly reference error upon deploying the website

I have a website, where the *.cs file lies in the App_Code folder (while adding a class item in my project, VS2010 suggested me to create this folder). I have a default.aspx.cs file which makes use of this class. It runs without any error when I run on VS2010.

However, when I deployed the website on the webserver via a private hosting company. It gives me this error: 

Compilation Error

Description: An error occurred during the compilation of a resource required to service this request. Please review the following specific error details and modify your source code appropriately. 

Compiler Error Message: CS0246: The type or namespace name 'SMSAPP' could not be found (are you missing a using directive or an assembly reference?)

And its pointing to the line of code where I am instantiating the object of the class: 

Line 84:         SMSAPP obj = new SMSAPP();

What exactly went wrong from the local version to the hosted version? Please help. Thanks.

What I learned:

Okay, so I haven't been able to run my project yet. But I learned few things which I would like to share- web applications and web sites are totally different things. Mine was a website, that's why the *.cs code's property did not have option to "Build Action" = "Compile". I converted my project from website to web application, and I could see the options being suggested in the answers here. However, no luck in the deployment.

Check in IIS manager if your web app is configured to use the correct .NET version

Check property of your *.cs files in App_Code. They should have Build Action as Compile

Check your local App_Code folder, somewhere there you must have a class SMSAPP.

You must have forgotten to upload this file.

Right mouse click on the .cs file and select properties then check if the "Build action" is set to "Compile"
