After Colin released Avanade's "Integration Pack for Microsoft Enterprise Library" on his avablog, I cooked you guys a version of the Enterprise Library Extensions that works within this integration pack.
All of the features: Envrionmental Overrides, Configuration Protector and Configuration Constants writer are now available from within Visual Studio 2005.
As a small bonus in this release I also added another configuration node that manages the appSettings section of your configuration file (can be used from within Visual Studio or the Configuration console).
(Managing appSettings from within Visual Studio)
Please note: There could be some minor glitches when editing appSettings from within Visual Studio, the focus within the propertygrid is lost after editing a "Key" property.
Colin told me he'll look into this for his next release.
