Cleanup AppFabric Dashboard Part 1: Old virtual paths and phantom applications on IIS

While you are working with IIS installing and uninstalling web applications you might run into this issue on AppFabric Dashboard:

Another example is this error message:

There are two steps necessary to get a cleaned AppFabric Dashboard.

Delete old virtual paths

Old virtual paths might remain in %windir%\system32\inetsrv\config\ApplicationHost.config. To get rid of these crappy virtual paths switch to command line tool and use the following script:

C:\Windows\System32\inetsrv>appcmd.exe list vdir

VDIR "Default Web Site/" (physicalPath:%SystemDrive%\inetpub\wwwroot)
VDIR "Default Web Site/Service/App1/" (physicalPath:C:\Service\App1)
VDIR "Default Web Site/Service/App2" (physicalPath:C:\Service\App2)
VDIR "Team Foundation Server/" (physicalPath:C:\Program Files\Microsoft Team Foundation Server 12.0\Tools\Templates)
VDIR "Team Foundation Server/tfs/" (physicalPath:C:\Program Files\Microsoft Team Foundation Server 12.0\Application Tier\Web Services)
VDIR "Team Foundation Server/tfs/queue/" (physicalPath:C:\Program Files\Microsoft Team Foundation Server 12.0\Application Tier\Message Queue)

C:\Windows\System32\inetsrv>appcmd.exe delete vdir "Default Web Site/Service/App1/"
VDIR object "Default Web Site/Service/App1/" deleted

Remove phantom applications

The file might also contain some obsolete application entries. I found the solution here.
Search for application XML nodes in your applicationHost.config file and delete them if the the application does no longer exist. Of course, do not forget to create a backup of the file before you start changing it.

To prevent this issue

Always remove deployments like this to avoid, or at least reduce the risk to run into this issue.

How to integrate AVM smart devices into HomeKit by using openHAB

After some evaluating openHAB (Vers. 2.2.0) on my NAS I wanted to do it right and started with this (German) article to use openHABian together with a Raspberry Pi.My primary goal was to integrate my AVM smart home devices to control them with HomeKit .

This is a dedicated linux distribution to provide an openHAB server. Download SD Formatter here . Needed to format your SD card. Download Etcher here . Needed to install the openHABian image on the SD card. Installation openHABian Insert the SD card Connect the Raspberry Pi via LAN with your network Plugin the Raspberry Pi Wait about 45 minutes until all updates were installed When everything went well you should be able to connect to http://openhabianpi:8080 Connect via ssh: ssh openh...

Have you ever reconsidered your personal iPhone security policy?

Why should I reconsider my iPhone security policy? I have my iPhone four digit pass code and Find my iPhone feature feature is activated. So how should abuse be possible? What could a thief be doing with my stolen iPhone? Well, possibly quite a lot. At least the bold print bullets in this article should be mandatory for everyone. Of course this is no guarantee for invulnerability but it will improve your security. After watching this video you should consider the following actions: Change your Apple ID rescue mail address and do not add this mail account to your iPhone. Consider to use a proper and usable password policy for your Apple ID like this or this (German article) . Consider a complex pass code for your iPhone. As you can see in the video four digit pass codes can be hacked in no time on iPhone 4. For newer iPhone a leak is not yet known but it is properly there. Definitely do not use these pass codes . Alternative to point three: activate delete iPhone after 10 wrong...

Two annoying issues in Visual Studio regarding XSDs and WCF should be fixed immediately

In my daily work I am always stumbling on two annoying features in Visual Studio, and I think it could be improved easily. Here is what I am complaining about. WCF Test Client WCF Test Client might be a nice tiny tool for small WCF tests, especially when you are testing smaller scenarios or when you are starting to learn how to implement web services with .NET. But it can be very annoying when you are working on more advanced stuff and your are testing with your local IIS. WCF Test Client always(!) starts automatically when you press F5 for debugging and your opened .svc.cs file has the focus: When I have configured local IIS is the target for debugging, then I expect my application will start with local IIS and not with WCF Test Client. Always. Here is my first urgent request: Please give me an option to disable WCF Test Client completely! Update 03.03.2014: Workaround for WCF Test Client Issue Select project file -> Right click -> Properties -> Web -> Sele...
