You can ditch packages.config and store the package references in the project file directly by following these instructions.
There are several advantages to this approach:
- Dependent packages are installed implicitly rather than cluttering up the package list
- Launching from the IDE is faster if the project is already built
- Full compatibility with Visual Studio for Windows
- Library dependencies propagate automatically to executables (no need to explicitly include them in the final APK or APP files)
I am not aware of any disadvantages at this time, but suggestions are welcome. There may be some reason that this project setting remains hidden.
