TFS: how to find checked out files in different workspace

 

My machine crashed and I wanted to find which files were checked out by me on that machine.

It wasn’t obvious, but finally I found, that I can search for user.

You need to have installed 

Team Foundation Server Power Tools

 

In Visual Studio- select menu File-Source Control Explorer – Find in Source Control– specify username and it will show all workspaces.

 

 

 

 

 

 

WCF: Suppress authentication for testing on different domain.

I have a WCF service and client, which worked fine, when I debug it on my local machine.

However when I deployed the service to test server on the different domain.

I’ve started to receive error

System.ServiceModel.Security.SecurityNegotiationException: The caller was not authenticated by the service. —> System.ServiceModel.FaultException: The request for security token could not be satisfied because authentication failed.

I’ve found a few similar recommendations, e.g.

 http://community.discountasp.net/showthread.php?t=7647, 

http://stackoverflow.com/questions/246636/wcf-changing-endpoint-address-results-in-securityexception

 that recommend to specify something like the following:

<wsHttpBinding>
                <binding name=”CustomBinding”>
                    <security mode=”None”>
                        <message establishSecurityContext=”false”/>
                        <transport clientCredentialType=”None”/>
                    </security>
                </binding>
            </wsHttpBinding>
 

 

Unfortunately, it didn’t work for me.

Fortunately, after I’ve replaced wsHttpBinding  to basicHttpBinding , my client is able to access the server.
