在IIS 7.0中托管Web服务（不是WCF）

Question

I have written a webservice in C# and am trying to host it on IIS 7.0. Consider the following code, this code works fine and can be hosted on IIS 7.0 with no problems:

using System;
using System.Collections.Generic;
using System.Collections.Specialized;
using System.Linq;
using System.Web;
using System.Web.Services;
using VMware;

namespace vmareService
{
/// <summary>
/// Summary description for Service1
/// </summary>
[WebService(Namespace = "http://tempuri.org/")]
[WebServiceBinding(ConformsTo = WsiProfiles.BasicProfile1_1)]
[System.ComponentModel.ToolboxItem(false)]
// To allow this Web Service to be called from script, using ASP.NET AJAX, uncomment the     following line. 
// [System.Web.Script.Services.ScriptService]
public class Service1 : System.Web.Services.WebService
{

    [WebMethod]

    public void logintoVmware(string URL, string username, string password)
          {
        VMware.Vim.VimClient client = new VMware.Vim.VimClient();

    }

}
}

Now if I want this method to return my session id, I change my code to following:

using System;
using System.Collections.Generic;
using System.Collections.Specialized;
using System.Linq;
using System.Web;
using System.Web.Services;
using VMware;

namespace vmareService
{
/// <summary>
/// Summary description for Service1
/// </summary>
[WebService(Namespace = "http://tempuri.org/")]
[WebServiceBinding(ConformsTo = WsiProfiles.BasicProfile1_1)]
[System.ComponentModel.ToolboxItem(false)]
// To allow this Web Service to be called from script, using ASP.NET AJAX, uncomment the     following line. 
// [System.Web.Script.Services.ScriptService]
public class Service1 : System.Web.Services.WebService
{

    [WebMethod]

    //public void logintoVmware(string URL, string username, string password)
    public VMware.Vim.UserSession logintoVmware(string URL, string username, string password)
    {
        VMware.Vim.VimClient client = new VMware.Vim.VimClient();
        VMware.Vim.UserSession session;
        session = client.Login(URL, username, password);
        return session;

    }

}
}

Now while I have referenced the vmware.vim.dll in my code and have also included the file in my folder hosted on IIS 7.0 ,, i get the following error message:

Server Error in '/vmService' Application.

any help would be appreciated..

You should make sure this file is in your /bin folder. If it is, then you should investigate what its potential dependencies may be. Remember, just because this file is there doesn't mean all of its dependent dlls are available.
