C# Web Services Compilation Error

I created a webservice that works fine on my local machine. However when I upload it to my host I get this error:

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

<%@ Assembly Name="MyAssembly" %>
or
<%@ Assembly Src="path/myFile.cs" %>

the error says, you are missing a reference to your BL class, you need to have BL class dll on the iis server in the bin folder, where your webservice is hosted.

hope this helps.

This my be a stupid question but my BL.cs is in my App_Code folder there is no dll made.
Wouldn't there be one made when I run the website?

I deployed the web site an I got the dll for the App_Code folder but I still get the same error.

Jitendra PatilSr.Software EngineerCommented:
have you checked the dependencies for your website, while deploying the site you need to check for dependiences (i.e.) dll files which are necessary for running your application,
in the app_code folder you got the dll, so while deploying the site your deployment should contain the dll file also.

for the error you are getting please refer the link below.
