Copilot auto-detects installed .NET skills like the WinForms expert and web API skills based on the solution. A new skill-value dashboard at github.com/dotnet/skills shows token usage and pass-rate improvements per model. NuGet packages can now ship their own Copilot skills via a 'dotnet package skills' command. Roslyn's new daemon mode cuts memory usage about 50% when running multiple agents simultaneously, and a 170-scenario .NET-specific benchmark catches regressions like a tool that spiked token usage before release. ## Full article daily.dev links to this article rather than hosting it. Read it at the original source: ## Questions this post answers ### How does Roslyn's daemon mode reduce memory usage when running multiple Copilot agents at once? Roslyn's new daemon mode shares resources across multiple agents instead of spinning up separate processes for each, cutting memory usage by about 50% in multi-agent scenarios. It is enabled through the .NET skills plugin configuration, which sets up agents to use LSP with Roslyn in daemon mode for code search, letting systems handle three or four simultaneous agents without slowing down. _Running several coding agents at once? daily.dev surfaces updates like Roslyn's daemon mode before memory issues hit._ ### Can NuGet packages ship their own Copilot agent skills? Yes, a new feature lets package maintainers bundle Copilot skills directly inside their NuGet package. When a developer runs 'dotnet restore', those skills download automatically to their machine, and a 'dotnet package skills' command copies them into the folder agents use to recognize and apply them. This was announced in a blog post by Richlander shortly before the demo. _Tracking new .NET tooling capabilities like packaged skills is easier with daily.dev in your workflow._ ### How does Microsoft test GitHub Copilot's reliability specifically for C# and .NET code? The .NET team built a custom benchmark of roughly 170 scenarios run regularly against top and frontier models, since mainstream agentic benchmarks contain no .NET or C# code. Visual Studio, VS Code, and the Copilot SDK teams all use it to catch regressions; it once caught a tool that boosted token usage past an acceptable threshold before release, and it led to a new C# refactoring skill after refactoring scenarios on large codebases kept failing. _Choosing an AI coding assistant for a C# codebase gets easier when you track benchmark results like these on daily.dev._ ## Similar posts on daily.dev -
