Getting COMException "Could not read key from registry (Exception from HRESULT: 0x80040150 (REGDB_E_READREGDB))" when instantiating WCF service

[eirik årdal]

Hi

I just posted this on StackOverflow as well, so if you'd like to answer there, please go ahead. Here is a copy & paste of my issue:

For a project at work we use Castle Windsor as our inversion of control container. In my team's project we depend on another team's WCF web services. The config for consuming these web services are set up in such a way that we will simply constructor inject the necessary interfaces from their library and then Castle Windsor creates and manages the WCF service instance.

This works fine for everyone in my team, except me. It used to work fine for me as well, but a couple of days ago I started getting the below stack trace whenever I hit code that require Castle Windsor to instantiate a WCF service:

Could not read key from registry (Exception from HRESULT: 0x80040150 (REGDB_E_READREGDB)) System.Runtime.InteropServices.COMException (0x80040150): Could not read key from registry (Exception from

I'm not sure why a call to my machine's registry is necessary, but apparantly there is something extracted from there in order to generate either a public key or get the name of a key. As mentioned, this is only an issue on my computer. The same code (same commits) runs just fine for everyone else on my team and in our dev environments.

Any ideas or tips are welcome at this stage.
