i try to follow Rob Windsor's Blog Posting to create a Custom Web Service in Sharepoint 2010.
Walkthrough: Creating a Custom ASP.NET (ASMX) Web Service in SharePoint 2010
it looks straight Forward. since the configuration is quite simple. I was with the following erorr.
Parser Error Message: The given assembly name or codebase was invalid. (Exception from HRESULT: 0x80131047)
Source Error:
Line 1: <%@ WebService CodeBehind="MyCustomWebService.asmx.cs" Class="WebServiceDemo.MyCustomWebService, Version=1.0.0.0, Culture=Neutral, PublicKeyToken=85b819cd95d3fe73" %>
when i google with the Error message. some solutio suggest that we should modify the trust level to be Full
this is a very risky approach to fix an issue. fortunately this is a solution. the root cause of this issue sterm from missing an element from the strong name of web service class. After i properly set the strong name of WebService Class. the web service link render successfully
the format of the strong name of web service class is
Class="ClassName with full path, Assembly Name, Version, Culture, PublicKeyToken"
here is specific for my web service.
<%@ WebService CodeBehind="MyCustomWebService.asmx.cs" Class="WebServiceDemo.MyCustomWebService,WebServiceDemo, Version=1.0.0.0, Culture=Neutral, PublicKeyToken=85b819cd95d3fe73" %>
It was the same problem for me. I followed the article and thought the ClassName and Assembly Name were one in the same. So I removed the Assembly Name.
