Retire Try.NET #50331
Description
See dotnet/try#1285
After nearly 8 years and over 1 billion code executions, Try .NET is retiring on December 31st, 2025.
When we launched in 2017, GitHub Codespaces didn't exist yet, C# Dev Kit was years away, and AI-powered coding wasn't on the horizon. Try .NET gave developers something they needed: the ability to experiment with C# directly in their browser, no setup required.
To fix this, remove the interactive snippets from articles in dotnet/docs and dotnet/dotnet-api-docs repositories.
In addition, rework the introductory tutorials for instructions using C# DevKit, and file-based apps.
