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?)

Here is the code

you can check you reference file

<%@ 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.

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.
Compiler Error CS0246
please refer the below links for hosting webservice in ii7.

hope this helps.
