NDepend is the only Visual Studio extension that is able to tell the developer that over the past hour, the code just written has introduced debt that would cost for example about 30 minutes should it have to be repaid later. Knowing this, the developer can fix the code before even committing it to the source control.

Native access to Excel files. The user doesn't need to have Excel, or any other software installed. XLSReadWriteII uses it's own memory manager that is optimized for storing cell values.

Xamarin Forms is great for developing apps on Android and iOS but it is missing some important features:

Scalable images
PCL and SharedLibrary, multi-screen / multi-resolution image management
HTML formatted text for labels and buttons
PCL and SharedLibrary custom font management
Android developers can use NinePatch bitmaps, the drawable directory naming convention, Html.FromHtml, and a bunch of complex file manipulations to address the image issue. Likewise, iOS developers can use ResizeableImageWithCapInsets, the @2x, @3x, @4x file naming convention, and some 3rd party libraries for this purpose. Forms 9 Patch enhances Xamarin Forms to make multi-resolution / multi-screen image management, custom fonts, and HTML text formatting easy for PCL and Shared Library apps for iOS and Android.
