.NET core spies on users by default
Lots of FUD as usual with these topics.<p>The .NET Core CLI/SDK dev tool to build and package code is the only thing sending telemetry. It's not the main `dotnet` command itself nor anything in the runtime. The data is also available for anyone to analyze: <a href="https://docs.microsoft.com/en-us/dotnet/core/tools/telemetry" rel="nofollow">https://docs.microsoft.com/en-us/dotnet/core/tools/telemetry</a><p>It's definitely nothing out of the ordinary and is common practice among many tools and apps you already use. Your smartphone sends back way more data if you're that concerned.<p>There's also a warning the first time you use it, and if you're using something like this then it's a reasonable expectation that as a software developer you understand the message and how to disable it if you want to.<p>EDIT: the insights based on this telemetry are also interesting to look at and add further clarity: <a href="https://blogs.msdn.microsoft.com/dotnet/2017/07/21/what-weve-learned-from-net-core-sdk-telemetry/" rel="nofollow">https://blogs.msdn.microsoft.com/dotnet/2017/07/21/what-weve...</a>
