I’m deploying a webpart on sharepoint and getting some errors. The webpart consumes data from a Web Service and displays a chart using Microsoft Chart (Framework 3.5). When I try to acces it, I get the folowing error:

Could not load file or assembly ‘System.ServiceModel, Version=3.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089’ or one of its dependencies. The system cannot find the file specified.

StackTrace: at System.Web.Services.Protocols.SoapHttpClientProtocol.ReadResponse(SoapClientMessage message, WebResponse response, Stream responseStream, Boolean asyncCall)
at System.Web.Services.Protocols.SoapHttpClientProtocol.Invoke(String methodName, Object[] parameters)

I tried copying System.Servicemodel.dll to the bin folder and registering it on the GAC, but the error does not change. Any idea?

Thanks

  1. The problem was within the Web Service, not the webpart. The machine where the web service was deployed has framework 2.0 installed. The exception was catched on the webpart and reported back. Thank you all for your comments.
