roslyn-code-analysis

I am using Roslyn to create an analyzer that warns users if a particular class exposes its fields in an unsynchronized manner, to help prevent race conditions. The Problem: I currently have working code that checks to make sure a field is private. I’m having trouble with the last piece of the puzzle: figuring out a way to make sure that all fields are only accessed inside a lock block, so they’re (ostensibly) synchronized. using System; using System.Collections.Generic; using System.Collections.Immutable; using System.Linq; using System.Threading; using Microsoft.CodeAnalysis; using Microsoft

In the implementation of my analyzer I am in the AnalyzeSymbol method: public override void Initialize(AnalysisContext context) { context.RegisterSymbolAction(AnalyzeSymbol, SymbolKind.Method); } private static void AnalyzeSymbol(SymbolAnalysisContext context) { // here I look through the syntax of the method body in order to find invocations. var methodSymbol = context.Symbol as IMethodSymbol; var location = methodSymbol.Locations.FirstOrDefault(); var methodNode = location.SourceTree.GetCompilationUnitRoot().FindNode(locati‌​on.SourceSpan); var blockNode = methodNode.ChildNodes()

I am working on a code analyser using Roslyn and my current task is to find all internal methods which are unused in the assembly. I start with a MethodDeclarationSyntax and get the symbol from that. I then use the FindCallersAsync method in SymbolFinder , but it returns an empty collection even when I am making a call to the method in question somewhere in the assembly. See the code below. protected override void Analyze(SyntaxNodeAnalysisContext context) { NodeToAnalyze = context.Node; var methodDeclaration = NodeToAnalyze as MethodDeclarationSyntax; if (methodDeclaration == null) return;

I'm working on little Roslyn project that includes changing parse tree and writing changes back to file. I've started with standalone code analyzer and want to build it as a command line app. I've encountered a challenge, though. Working with: Find classes which derive from a specific base class with Roslyn partially, and mostly with: https://github.com/dotnet/roslyn/wiki/Getting-Started-C%23-Syntax-Analysis I've created this small project: class Program { static void Main(string[] args) { try { if (args.Length < 1) throw new ArgumentException(); SyntaxTree tree = CSharpSyntaxTree.ParseText

I am successfully getting dependencies between projects with Roslyn, and now I would like to get dependencies between classes, similar to the Code Map feature in Visual Studio Enterprise. Here is my code, the "?????" part is where I imagine I could get something. I am very new to the Roslyn API, though, and I don't know how to proceed from there on. Solution solution = MSBuildWorkspace.Create() .OpenSolutionAsync(Path.Combine(repoRootFolder, "MySolution.sln")) .Result; ProjectDependencyGraph projdeps = solution.GetProjectDependencyGraph(); Digraph graph = new Digraph(); foreach (ProjectId

What is the best general purpose way to get a System.Type from Microsoft.CodeAnalysis.ISymbol for different types of symbols ? (e.g. class declarations, variable, properties, etc) I want to be able to do various checks on the type e.g. as checking if the type implements any interface or is cast-able to any interface, just like one can check on System.Type. The problem I am having is that most of the concrete classes used to represent the symbol are internal (see http://source.roslyn.io/ ) and I could not find tye type information in the ISymbol. SourceNamedTypeSymbol LocalSymbol I retrieve the
