Migrate a .NET 10 project or solution to .NET 11 and resolve all breaking changes. This is a MIGRATION skill — use it when upgrading from .NET 10 to .NET 11, NOT for writing new programs. USE FOR: upgrading TargetFramework from net10.0 to net11.0, fixing build errors after updating the .NET 11 SDK, resolving source-breaking and behavioral changes in .NET 11 runtime, C# 15 compiler, and EF Core 11, adapting to updated minimum hardware requirements (x86-64-v2, Arm64 LSE), and updating CI/CD…
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# .NET 10 → .NET 11 Migration Migrate a .NET 10 project or solution to .NET 11, systematically resolving all breaking changes. The outcome is a project targeting `net11.0` that builds cleanly, passes tests, and accounts for every behavioral, source-incompatible, and binary-incompatible change introduced in .NET 11. > **Note:** .NET 11 is currently in preview. This skill covers breaking changes documented through Preview 3. ## When to Use - Upgrading `TargetFramework` from `net10.0` to `net11.0` - Resolving build errors or new warnings after updating the .NET 11 SDK - Adapting to behavioral changes in .NET 11 runtime, ASP.NET Core 11, or EF Core 11 - Updating CI/CD pipelines, Dockerfiles, or deployment scripts for .NET 11 - Fixing C# 15 compiler breaking changes after SDK upgrade ## When Not to Use - The project already targets `net11.0` and builds cleanly — migration is done - Upgrading from .NET 9 or earlier — address the .NET 9→10 breaking changes first - Migrating from .NET Framework — that is a separate, larger effort - Greenfield projects that start on .NET 11 (no migration needed) ## Inputs | Input | Required | Description | |-------|----------|-------------| …

How to install
mdr add dotnet/skills/migrate-dotnet10-to-dotnet11@sha256:63dc826d2cbe5a1bThe line at the top of this page pins the label git:20260511.fe11dec, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
