Getting Started



The binaries needed for the SDK are hosted by PKWARE. The SDK is split into components so you can pick and choose the components your application needs.


Create a NuGet.Config file at the root of your project, next to your .sln file, with the following content

<?xml version="1.0" encoding="utf-8"?>
        <add key="PKWARE" value="" />
            <add key="Username" value="your_username" />
            <add key="ClearTextPassword" value="your_password" />


If not using NuGet, or if unable to reach the PKWARE NuGet server, you can download the required files manually.
