That PR description contradicts itself. At the very top it says "Visual Studio 2022 17.14 or earlier versions." while at the bottom it says "MSBuild version < 17.14.0". Also, why mention the minor version at all? If VS 2026/MSBuild 18 is required, just say "Targeting .NET 10.0 or higher in Visual Studio 2022 is not supported." (without mentioning any version number). |

Done! I've updated the code with all the requested changes:
The compatibility warning will now require Visual Studio 18.0 or higher for .NET 10.0 projects. Changes committed in ab74179. |

The PR description still contradicts itself. Now the top is wrong and the bottom is correct. And the user facing message was not changed. |
… conflicts when flowing up

This change can't go in until we have VS 2026 previews in our hosting images so this'll have to wait for that, likely in GA. |

@copilot We now have VS 2026 images for running tests in helix. Please update to use "windows.amd64.vs2026.pre.scout.open" for public PRs and "windows.amd64.vs2026.pre.scout" in the .vsts-pr.yml and .vsts-ci.yml files, respectively. |

@copilot a few AOT tests appear to be having issues with the new dev18 image. Please disable the following for tests by skipping them and link to this issue in the skip message: #51361

@copilot VS 18 doesn't support targeting 4.5.2 anymore. Please update the following tests to target 4.6.2 anywhere they were targeting 4.5.2 before:

@copilot when removing a message, we have to update a test that checks for gaps in the error numbers. This PR removes NETSDK1223 so please update ThereAreNoGapsDuplicatesOrIncorrectlyFormattedCodes to account for that warning being removed. |

The MSBuild version check of 17.15.0 is inconsistent with the error message mentioning Visual Studio 2022 17.14. The comment above explains that 'MSBuild was 17.15 during previews for dev18,' but the error message warns about VS 2022 17.14. Consider either updating the error message to reference MSBuild 17.15 or the version check to align with VS 2022 17.14, or adding a comment explaining this intentional version mismatch.

| <!-- | |
| MSBuild was 17.15 during previews for dev18 so require that or higher. | |
| Note: The warning message references Visual Studio 2022 17.14, but the version check is for MSBuild 17.15.0. | |
| This is intentional because MSBuild 17.15 shipped in previews for dev18, while the last stable VS 2022 release was 17.14. | |
| The warning is shown for users with VS 2022 17.14 or earlier, but the actual check is for MSBuild 17.15.0 or higher. | |
