Hello,
I have the following problem. I used the wsdl.exe to generate the proxy
class of some web service. It works fine, until I get the error "An unhandled
exception of type 'System.ExecutionEngineException' occurred in
system.web.services.dll". This error occurs on the line  MyBase.New() . When
I get this error once, I will get it forever (restart of aplication, IIS or
computer doesn't help).  
Here is the code:

<System.ComponentModel.DesignerCategoryAttribute("code"), _
System.Web.Services.WebServiceBindingAttribute(Name:="pgwSoapBinding",
[Namespace]:=some url)> _
Public Class MUZOWSHandler
   Inherits System.Web.Services.Protocols.SoapHttpClientProtocol

   '<remarks/>
   Public Sub New()
       MyBase.New()  'Here I sometimes get error
       Me.Url = some url
   End Sub

.
.
.
