Analyzing source code using Roslyn
summary
Shows how Roslyn parses student C# submissions on exercism.io, then normalizes code, detects patterns, and compiles to run tests. Demonstrates concrete analyzers that find method overloading and suggest optional parameters, replace default null with a string literal, recommend string interpolation and expression-bodied members, and rewrite AST nodes to normalize whitespace, usings, comments and identifiers. Builds an in-memory assembly from a Project using MSBuildWorkspace and runs xUnit tests via the runner; uses Roslyn syntax trees to transform and compare solutions.
