Add a “go fix" style tool for automated modernization of the codebases #53115
Description
Is your feature request related to a problem? Please describe.
Updating large .NET codebases to newer APIs and language features is manual and time consuming.
Describe the solution you'd like
Similar to go fix, create an equivalent command or tool that scans the codebase, identifies deprecated APIs and outdated patterns, and automatically applies safe refactorings (probably with a dry run option)
