http://blogs.msdn.com/b/aaronmar/archive/2009/11/06/all-your-regkeys-are-belong-to-us.aspxI’ve been in many discussions lately with various folks about Visual Studio 2010 extensibility. Inevitably, someone suggests a solution to some problem involving changing/adding/deleting a registry key/value for an extension.

If you are hosted in the shell app and have an IServiceProvider, you can use the new &quot;SettingsStore&quot; classes in Microsoft.VisualStudio.Shell.10 to read registry values.</p> <div style="clear:both;"></div><img src="http://blogs.msdn.com/aggbug.aspx?PostID=9923678" width="1" height="1">http://blogs.msdn.com/b/aaronmar/archive/2009/11/06/all-your-regkeys-are-belong-to-us.aspx#9923643Tue, 17 Nov 2009 16:15:15 GMT91d46819-8472-40ad-a661-2c78acb4018c:9923643Julien Lebosquain<P>Hello and thanks for the warning, I was struggling with these magical self-reappearing keys.</P> <P>However, how can I remove information for a specific instance? My problem is that I have ReSharper installed (in HKLM), but I don't want it to be loaded for the experimental instance. First I was simply deleting the package from the 10.0Exp_Config but to no avail since the key is automatically recreated from HKLM. Deleting the package from HKLM is not an option since I want ReSharper to continue loading for the normal VS instance.</P> <P>I can't seem to find a proper way to do this. Should I run a script that will delete/create the package key and then run devenv with the instance I want? It seems to defeat the purpose of the exp instance...
