How to use XDT in NuGet – Examples and Facts
Starting with NuGet 2.6, XML-Document-Transform (XDT) is supported to transform XML files inside a project. The XDT syntax can be utilized in the .install.xdt and .uninstall.xdt file(s) under the package's Content folder, which will be applied during package installation and uninstallation time, respectively. One of XDT’s greatest strengths is its simple but powerful syntax for manipulating the structure of an XML DOM.

Visual Studio 2013 Custom Web Servers and OwinHost.exe
When running Web applications from within Visual Studio, there have generally been two primary hosts available while developing: a local “development” Web server, or a full version of Internet Information Services (IIS). There has also been a “custom server” option, where a path to a server executable could be entered; however, this was not a widely used option given that most Web applications were built for the ASP.NET pipeline running in some flavor of IIS anyway. With Visual Studio 2013, ASP.NET will include a new way to compose and host Web applications. In this new model, ASP.NET will shift from a monolithi...
