Version information

It's usually best to send back all of the information from the Copy Information buttons. Otherwise we will often need to request additional information. For example, operating system versions, Xcode version, installed Android API levels, and .NET version can all be important when helping to troubleshoot a problem.

Windows version information

Xamarin Studio

Help > About > Show Details > Copy Information [button]

Visual Studio

Help > About Microsoft Visual Studio > Copy Info [button]

Mac version information

Visual Studio for Mac

Visual Studio > About Visual Studio > Show Details > Copy Information [button]

Android SDK Tools, Platform-tools, Build-tools

Open the Android SDK Manager, and take a screenshot of the top Tools section.
