I have created a virtual folder on "Default Web Site" on IIS Manager. I use IIS 7.0 and Windows Server 2008.
I have looked at tenths of forums and they all say these things:
There may be something with IIS 7.0
The namespace of the class attribute in the .asmx file is not good (in my case, it is)
If the class name containing the Web service is Service, then it may not work (a bug)
The build action of the
.asmxfile must beContent(it is).The build action of the
.asmx.csfile must be Compile (it is).The code must be in an
App_Codedirectory in the "virtual directory" and the.asmxfile must include the correct file in the CodeBehind attribute (I have tried, but it didn't work).
This is the directory structure
- App_Data
- bin
- GeocachingServer.asmx
- GeocachingServer.asmx.cs
- GeocachingServer.dll
- GeocachingServer.pdb
- obj
- Debug
- Refactor
- TempPE
- GeocachingServer.dll
- GeocachingServer.pdb
- Server.csproj.FileListAbsolute.txt
- Properties
- AssemblyInfo.cs
- Example09ServiceWeb.Publish.xml
- GeocachingServer.asmx
- GeocachingServer.asmx.cs
- Server.csproj
- Server.csproj.user
- Server.Publish.xml
- Web.config
- x.html (if I ask this file when specifying the URL, it works)
This is my web.config file:

After six hours of debugging, I didn't found the solution to my problem. Please help!
If you are using a Web Site project, you should be putting your codebehind GeocachingServer.asmx.cs in the ~/App_Code/ directory and pointing to that path in the .asmx
If that didn't work, you forgot to right click on your virtual directory and pick Convert to Application.
Although you should have created an application on that folder in the first place, instead of making it a virtual Directory. You should click Add Application when creating it.
I have found a workaround solution: put the .asmx.cs code after the first line of the .asmx file and remove the CodeBehind attribute on the first line of the .asmx file.
My problem was that I changed the Namespace I was using. The asmx.cs had the Namespace change, however the old value was still in the Class property of the markup. You have to right-click the asmx file and select "View Markup" in order to see the markup and make the necessary changes.
The solution for us was to delete the .asmx and .asmx.cs files, SVN update to get them back, and rebuild.
We didn't bother to look any further because it worked, but here are a couple of theories:
- bad file encoding
- VS2010 caching of old files and not properly reloading the new ones.
Anyway, you've got another thing to try.
We solved this problem by uploading the Web.csproj file to our continuous integration server. It includes the references to \api* so service was never being built.
Another reason can be that your code behind (.cs) file has class name different from which specified in .asmx file. Open .asxm file with XML editor to see what class name specified in it.
The solution to this error in my case was that the project url in the project properties had a typo and was not publishing where expected.
Just in case it helps anyone else, for me it was a missing Microsoft.Web.Services3.dll file that caused it. Theirs a nuget package https://www.nuget.org/packages/Microsoft.Web.Services3
Was fine on a 2008R2 server but on a 2019 it failed guess something was installed on the older server which added that dll to the GAC.
