Users can install Microsoft Office solutions by opening the deployment manifest from the Web. However, a secured installation of Internet Information Services (IIS) will block the .vsto file name extension. The MIME type must be defined in IIS before you deploy Office solutions by using IIS.

I am currently migrating Tech Head Brothers Authoring tool to Visual Studio 2008! And found this cool feature, it is crazy that you use a tool for quite some time (VS05) and always find little trick like that.

Following my post "Visual Studio and PowerShell Trick" I had another little issue, I have one mapping file, mapping.xml, that I want to use on my website and with my data access layer unit tests project.
This end of afternoon I worked on the mapping part of my new project for innoveo solutions, a blog engine.
Till now I was using the XML Persistence Engine of Euss but it was time to go to a real mapping and a database.
