Incremental analysis #76485

Is there a way to do incremental code analysis? That is, the new code is analyzed and only the new issues are shown. |

Yes. This is how Roslyn analyzers already work. |

Whenever I run the analysis on a project in Visual Studio I get the issues on all the solution code, if it really works like this, please could you explain how to get it or where the documentation is that explains it? |

I understand that default behavior is incremental, I'm going to rephrase the initial question. Could the results of the analysis be saved in a file and obtain the results of the changes with respect to that saved file? |

Sure. I imagine that is something that could be done. |

But, to be clear, it is not something that Roslyn supports today, and not something that we're interested in implementing for either VS or VS Code. |

Note: the easiest way to accomplish this yourself would be to just have roslyn run as a library in some command line tool you create. Have it analyze everything, and write all those analysis results to a file. Then do the same in the future. But instead of writing out everything, do a diff between what you are producing now and what was produced the last time, and only write out the diff. |
