.NET CLI Telemetry Data
The .NET SDK includes a telemetry feature that collects usage and failure data about the .NET CLI. The CLI is the set of verbs that enable you to build, test, and publish your apps. Telemetry is not collected from .NET applications. For more information, see the .NET SDK telemetry article.
This report summarizes the total usage collected on September 1, 2026 for the previous 90 days.
Challenges with the data
There are significant challenges in understanding .NET CLI usage data. The biggest one is that we don't know how many developers directly use the .NET SDK, even though we have a total count of hashed MAC addresses (shared in the following section). We believe that a significant portion of the usage data is generated by regularly running build and continuous integration machines, as opposed to people. We also believe that some environments frequently change MAC addresses (and therefore the hash we receive) while others re-use a small set (like Docker). This means it is really hard to reason about MAC addresses, since there is both artificial expansion and compression of these addresses at play.
Total MAC address count
The total count of unique Mac address hashes is: 132,497,872.
