Roslyn / Find References - Can't properly load Workspace
c#, mono.cecil, roslyn, static-analysis
Solution
CustomWorkspace is
A workspace that allows manual addition of projects and documents.
Since you're trying to load a solution, you should use the MSBuildWorkspace, which is
A workspace that can be populated by opening MSBuild solution and project files.
You can create a new `MSBuildWorkspace` and call `OpenSolutionAsync` with your `solutionPath`. For the reference finding part, take a look at the `SymbolFinder`.
Problem
I'm trying to write some code to find all method invocations of any given method as I am looking to create an open source UML Sequence Diagramming tool. I'm having trouble, however, getting past the first few lines of code :/ The API appears to have changed drastically and I can't seem to infer proper usage by looking at the code. When I do: ``` var workspace = new CustomWorkspace(); string solutionPath = @"C:\Workspace\RoslynTest\RoslynTest.sln"; var solution = workspace.CurrentSolution; ``` I find that workspace.CurrentSolution has 0 Projects. I figured this would be the equivalent to what was previously `Workspace.LoadSolution( string solutionFile )` which would then supposedly contain any Projects in the Solution, but I am not finding any success with this path. I am terribly confused 0.o If someone could offer some additional guidance as to how I can use the FindReferences API to identify all invocations of a particular method, it would be very much appreciated! Alternatively, would I be better off taking a static-analysis approach? I would like to support things like lambdas, iterator methods and async. ==================================================================== Edit - Here is a full example based on the accepted answer: ``` using System.Linq; using Microsoft.CodeAnalysis.CSharp; using Microsoft.CodeAnalysis.CSharp.Syntax; using Microsoft.CodeAnalysis.MSBuild; using Microsoft.CodeAnalysis.FindSymbols; using System.Diagnostics; namespace RoslynTest { class Program { static void Main(string[] args) { string solutionPath = @"C:\Workspace\RoslynTest\RoslynTest.sln"; var workspace = MSBuildWorkspace.Create(); var solution = workspace.OpenSolutionAsync(solutionPath).Result; var project = solution.Projects.Where(p => p.Name == "RoslynTest").First(); var compilation = project.GetCompilationAsync().Result; var programClass = compilation.GetTypeByMetadataName("RoslynTest.Program"); var barMethod = programClass.GetMembers("Bar").First(); var fooMethod = programClass.GetMembers("Foo").First(); var barResult = SymbolFinder.FindReferencesAsync(barMethod, solution).Result.ToList(); var fooResult = SymbolFinder.FindReferencesAsync(fooMethod, solution).Result.ToList(); Debug.Assert(barResult.First().Locations.Count() == 1); Debug.Assert(fooResult.First().Locations.Count() == 0); } public bool Foo() { return "Bar" == Bar(); } public string Bar() { return "Bar"; } } } ```
