Как попросить ИИ, чтобы потом выжимку дал не больше тыщи слов?

Нефиг делать. Находим нужный ИИ, просим обзор. После, кидаем другому и просим сократить до 1000 слов.

Но при этом теряется эффект присутствия

Visual Studio 2026 is a major release focused on speed, developer productivity, AI integration, and a more modern, customizable interface. Here’s a concise summary of its key features:

• Performance Improvements:
  • Solution load times and startup are up to 30–50% faster compared to VS2022, thanks to underlying debugger and .NET runtime optimizations.
  • UI remains responsive during large solution/project loads, with much lower memory usage and fewer hangs.microsoft+2
  • Code file opening and CodeLens loading are much snappier.
• Modern Fluent UI:
  • Complete refresh with Microsoft’s Fluent UI design language: clearer typography, icons, layout, dark/light mode consistency.learn.microsoft+2
  • New “Editor Appearance” settings let you fully customize the look and feel of the coding environment.

  • Context-aware Copilot throughout the IDE, including adaptive paste (auto-fix pasted code style/names/errors).
  • New Copilot-powered tools for performance insights, debugging, code actions, and test generation directly from context menus and editor panes.visualstudio.microsoft+2
  • Copilot can now visualize Mermaid charts (flowcharts, diagrams) in Markdown and chat, supporting both user-typed and AI-generated syntax.
• Enhanced Debugging:
  • Inline if-statement evaluation displays results inside your code for faster logic inspection.
  • Improved profiler dashboard, memory allocation optimization in CodeLens, and expanded CPU/event/file I/O analysis for CMake/C++ projects.
• Razor & Blazor Tooling:
  • Significant compiler and memory optimization, especially for large Blazor solutions, delivering faster builds and less overhead.learn.microsoft
  • Razor Hot Reload with auto-restart support for rude edits.
• Cloud & Container Development:
  • Expanded support for Docker, Kubernetes, and DevSecOps practices.
  • Easier cloud-native workflow integration (Azure, Aspire, MCP).
• Productivity Enhancements:
  • Fast scrolling, better markdown preview and zoom controls.
  • One-click file exclusion in search, improved keyboard shortcuts, and a modernized settings experience.
• Other Notables:
  • Full .NET 10 & C# 14 feature support.
  • Stable and Insiders Channel release model for rapid updates.

Summary: "Build better web apps with Blazor in .NET 10"

• Presenter: Daniel Roth, Principal Product Manager for ASP.NET Core and Blazor.
• Key Focus: The video showcases how Blazor in .NET 10 enables secure, high-performance, and developer-friendly web app development entirely in C#, with no need for JavaScript.

Main Topics and Enhancements:

• Security and Authentication:
  • Built-in support for passwordless authentication using WebAuthN and passkeys.
  • New authentication scaffolders, including easier setup for Entra ID.
  • Passkeys are integrated into the Blazor template, allowing users to authenticate with cryptographic credentials managed by an authenticator app.
• Observability & Diagnostics:
  • Enhanced metrics for Blazor apps: page navigations, UI events, active circuits (current app users), and more.
  • Improved tracing and diagnostic tools for both Blazor Server and WebAssembly, including collecting performance profiles and memory dumps, which can be analyzed in Visual Studio.
  • .NET Aspire integration supporting distributed tracing and diagnostics dashboards.
• Performance:
  • Major framework optimizations: fingerprinted/pre-compressed/cached scripts, faster app startup and rendering (20% faster component rendering on WebAssembly compared to .NET 9).
  • Real-world improvements, e.g., Copilot Studio saw significant load/execution gains by upgrading from .NET 6 to .NET 8.
• Developer Experience:
  • Faster and more reliable Hot Reload (Visual Studio 2026 vs 2022: down from 40s to 3s for big apps).
  • Component state persistence, simplifying pre-rendering and improving resilience/scalability (automatic persistence for disconnected circuits).
  • Enhanced form validation, supporting deep/nested models.
  • Improved navigation, error handling, and integration testing (Kestrel + Playwright browser tests).
  • QuickGrid and JavaScript interop enhancements.
• Use Cases Highlighted:
  • "My Ride K-2" app for US/Canada schools demonstrates cross-platform agility.
  • LKAB (Europe’s largest iron ore producer) unified their mobile strategy using Blazor/.NET MAUI.
  • Blazor's powerful SSR model enabling rich interactive AI experiences (with provided chat template).
• Conclusion: Blazor in .NET 10 delivers major improvements in security, performance, diagnostics, and developer productivity, streamlining full-stack development in C# and .NET for web and cross-platform apps. Developers are encouraged to start using Blazor in .NET 10 and explore these new features.youtube
