Answer 1

I had this.. fixed it.. thought I'd share

if you right click the .asmx file and select view markup you'll see it still says

<%@ WebService Language="C#" CodeBehind="MyService.asmx.cs" Class="MyProject.Service1" %>

maybe not Service1.. but won't be the class you've just made

<%@ WebService Language="C#" CodeBehind="MyService.asmx.cs" Class="MyProject.MyService" %>

save it.. try it..

worked for me..

Answer 2

I've come across this error using Visual Studio Development Server when my project output directory was not bin\

One of my DLLs has versions for different platforms (x86, x64), so I created corresponding configurations, and they got by default output directories like this:

bin\x86\Debug 
bin\x64\Debug

But the Visual Studio Development Server still tried to load binaries from the bin\ folder and of course failed.

I fixed the issue by specifying bin\ output folder in my debug configurations.

You usually get that when your code doesn't build, i.e. there is no dll so i can't load the handler type.
