First against the .NET release lifecycle: net9.0 ended on 2026-05-12, net8.0 ends on 2026-11-10, net10.0 runs to 2028-11-14. Then against the support period you promise buyers, reporting the months of promised patching that land after your runtime stops being patched.
Maintainers of .NET and .NET MAUI products sold into the EU, who under the Cyber Resilience Act must determine a support period of at least 5 years and hold it. Also anyone inheriting a solution and needing to know, by date, which of its projects are already unpatched before quoting the upgrade.
Lifecycle dates move and models answer from a training snapshot, confidently naming the wrong month. This gate carries the dates as data and does the subtraction against your file and today's date, so the answer is a day count you can put in a ticket rather than a sentence you have to verify.
Dating the file you have open is free forever and needs no key: all 10 checks, every date, every day count. The licensed part is a different job - sweeping every project file in the workspace at once and writing the dated support-window evidence file you keep for an audit.
Inventorying target frameworks, SDK pins and runtime-bound packages across a real solution, dating each against the lifecycle, and writing the evidence page is commonly quoted as a multi-day consulting engagement. The gate is $29 once, with a 7-day full refund, and the free tier already answers the single-file question.
