Error when expanding datasources: Could not load System.ServiceModel

Posted By:      Posted Date: October 15, 2010    Points: 0   Category :WPF
 

I am not sure if this is the right  forum, so let me know if I need to post elsewhere.

I am developing a standard ASMX web service for use with WPF/Silverlight applications (as well as other apps).  

However, when I create a new .NET 4 WPF or Silverlight application and add a service reference to my ASMX (not SVC), it lists all of the methods in the datasource pane fine, but when I try to show the contents, I get an error:

Could not load file or assembly 'System.ServiceModel, Version=2.0.5.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35' or one of its dependencies.  The system cannot find the file specified.

Is there something in the service configuration that I need to do, or is there something wrong with my web service?   In .NET 3.5 I do not get an error, but it doesn't show me the contents of the data sources either.  

Anyone have any ideas?

Sudden Error: Could not load type System.ServiceModel.Activation.HttpModule - Urgent Help Please

  
hi,

I have a windows 7 machine with IIS 7. I was hosting WCF services on IIS normally and i had a couple of services running.
Suddenly (i honestly did not do any configuration changes on my machine) all these services stopped working. When i try to browse the .svc file i get the following error:


"Could not load type 'System.ServiceModel.Activation.HttpModule' from assembly 'System.ServiceModel, Version=3.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089'"

Just in case this information is helpful, all these services are running on the basicHttpBinding.

Please help!

Business Data Error: System.OverFlowException

  

I have a Business Data Catalog file I've uploaded to connect to our back end Firebird DBMS through ODBC.

The SharePoint server is MOSS 2007 x64. The web front end server(s) all have an x64 Firebird Engine and ODBC driver with verified connectivity to Firebird.

When I use one of the methods, I can see connections being made to our Firebird server and the query being passed. I know the query returns results (it's a stored procedure with no parameters), but I get the following error "An error occurred while retrieving data from MROTest1. Administrators, see the server log for more information" in IE. If I look in the server logs, I see (12\Hive\Logs)

Can Not load WPF project in Visual Studio 2005 on Win7 64 system, says "Project file not supported b

  
Dear all I am facing an issue in creating new wpf project or loading a WPF project in Visual studio 2005. I have installed Visual Studio 2005 Service pack - 1 (http://www.microsoft.com/downloads/details.aspx?familyid=bb4a75ab-e2d4-4c96-b39d-37baf6b5b1dc&displaylang=en) but still I can not see the option for wpf project  while creating a new project. Generally we can see WPF listing under item File -->New-->Project--> ".Net Framework 3.0" in VS 2005. I have few WPF project and when i try to load them it says "Project file not supported by this Installation". My System Config is given below: OS: Windows 7 (64 Bit) VS: Visual Studio 2005 with Service Pack 1 .Net Framework: 3.5 (By default inbuilt in Win7 OS)   I am suspecting something bugging related to .Net framework 3.0 in Win7. We have one option in control panel to alter .NetFramework 3.5 under "Turn Windows Features on or Off" but there I can not see something related to 3.0 :-(.   Kindly suggest how can I load my existing project and how can enable option to create new wpf Projects.   I saw few solutions suggested by people on following Thread bt most of them related to Windows XP or Vista: http://social.msdn.microsoft.com/Forums/en/vswpfdesigner/thread/06cf7bca-982c-44cf-aec9-99cf399b3000 Do someone has solution for Windows 7 (64 bit OS)

System.Messaging - Error accessing properties of remote private queues - "UnsupportedFormatNameExcep

  
I'm having some difficulty accessing private queues on a remote machine, but no trouble using remote public queues or private queues on a local machine. Calling: System.Messaging.MessageQueue.GetPrivateQueuesByMachine("machine"); ..succesfully returns the array of private queues on the remote machine.  However, trying to access nearly all of the properties on these MessageQueue objects returns: MessageQueueErrorCode: UnsupportedFormatNameOperation Message:"The specified format name does not support the requested operation. For example, a direct queue format name cannot be deleted." I have no trouble accessing queues created identically on the local machine using GetPrivateQueuesByMachine("."), plus accessing public queues using GetPublicQueuesByMachine("machine") also returns MessageQueue objects that are useable. The FormatName returned appears to be valid, as you would expect from queues retreived via GetPrivateQueuesByMachine().  e.g: FormatName:Direct=OS:machine\\private$\\example ..so I think the error message returned may be somewhat spurious. The permissions on the queues all appear to be set correctly.  I had even attempted allowing "Full Control" to "Everyone" on these queues as an experiment, with the same results. Any ideas for other things I might try? p.s. I am running Windows XP SP2, using .NET 2.

System.Data.SqlClient.SqlException: Bulk load data was expected but not sent

  
Hi everyone We've had this error twice now from our C# code. Nothing is changing the columns, but I've noticed though that it appears to happen when two threads are attempting to bulk insert into the same table, generally millions of rows. The docs say that SqlBulkCopy.WriteToServer is not guaranteed to be thread-safe, but is this the problem here? It feels like it. I've seen some posts where people appeared to have experienced problems in similar circumstances (http://social.msdn.microsoft.com/forums/en-US/sqldatabaseengine/thread/85d51484-6381-46bc-bcce-63b58b362d2d). There is no identity column just a non-unique clustered index that is (spid) process keyed to each thread. Do I need to synchronise access to the table for WriteToServer - is this a known problem? Many thanks Reg --- System.Data.SqlClient.
