Automate yourself out of a job with Roslyn
summary
Shows using Roslyn plus Microsoft.Build.Locator and MSBuildWorkspace to load .sln files, then reads SyntaxTrees and uses a SemanticModel to disambiguate types (system.string vs domain types). Demonstrates faster traversal with a CSharpSyntaxWalker vs LINQ queries, builds a CSharpSyntaxRewriter to append .ToUpperInvariant to literal strings (handles immutability by producing a new Solution and calling workspace.ApplyChanges), and describes a real project that auto-generates gRPC protobuf and adapter code from WCF contracts — it works, but needs autogenerated-file and symbol checks.
