WCF Test Client: Failed adding service

Question

 

Hi,

 

I installed the VS2008 beta 2 on a pretty clean WINXP PRO SP2 and when trying to run the defauld WCF service library, I get error messages:

 

svcutil.exe has encountered a problem and needs to close....

WCF Test Client: Failed adding service./
Unhandled Exception: System.IO.FileLoadException: Could not load file or assembly 'svcutil, Version=3.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a' or one of its dependencies. Strong name validation failed. (Exception from HRESULT: 0x8013141A)
File name: 'svcutil, Version=3.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a' ---> System.Security.SecurityException: Strong name validation failed. (Exception from HRESULT: 0x8013141A)
The Zone of the assembly that failed was:
MyComputer

 

What can it be?

 

Thanks,

Nuno

Answer 1

 

This is a known issue in Beta2. Svcutil.exe is not signed correctly.

1.       Open the VS command prompt.

2.       Browse to the bin directory of the windows SDK

3.       Type: sn –Vr svcutil.exe

You only need to do this once. The test client will work.

Answer 2

This fixed my problem. But I got another one right after the fix. Here is what I did:

1) Create a new WF Service Library

2) Added a Code activity inside the Receive Activity that looked like this:

 

private void codeActivity1_ExecuteCode(object sender, EventArgs e)

{

     returnValue = "Hello " + inputMessage;

}

 

3) Hit F5 to run it.

 

The WCF Test Client Starts, and when "Adding service..." I get the error below. I tried the following fixes (unsuccessfully)

a) disable the firewall

b) changing the port to make sure I use a free one in my machine

c) start VS as admin.

 

I'm using Orcas beta 2, on Vista.

Regards,

 

Nestor

To enable just-in-time (JIT) debugging, the .config file for this

Are you shure you've specified not null input parameter? It works fine on my PC.

In Vista we have to give the rights to edit registry before executing this command. Otherwise this is what you will get.

C:\Program Files\Microsoft SDKs\Windows\v6.0A\bin>sn -Vr svcutil.exe

Microsoft (R) .NET Framework Strong Name Utility  Version 3.5.20706.1
Copyright (c) Microsoft Corporation.  All rights reserved.

Failed to open registry key -- Access is denied.

 

 

Answer 5

Well This exact thing happened to me.  I have XP service Pack2 using vs 2008 ... I went as far as deleting version 2 and service packs, 3 and 3.5.  When I was removing version 3.5 it took over 30 minutes and the same for replacing it.  My error was trying to create the classes using the "SvcUtil.exe

"".

I get the "strong name ...." error and the utility exits with an unknown erreor.  I have tried to go around using the "snremove" utility and it can identified the .net framework as having the strong name ...." however it can not open the dll to remove it.

I have been having a lot of odd problems such as at time not being able to debug.  Components not being recognized or Master files having unknown error...

I could really use some help........the PC has been sending the errors to microsoft so by now they probably have a good 60, 70 of them ...

Thanks

Answer 7

 

In Vista, you can also right-click the VS 2008 command prompt and choose 'Run as Administrator' and run the sn -Vr svcutil.exe command.

Or you could use a better tool, something like WCFStorm, http://www.wcfstorm.com .  I've been using it for some time and I'm impressed.  I used to use WcfTestClient and WCF Load Test, but now I only use WCFStorm.  You should check it out.
