I wrote my class MonitorSyntaxRewriter, which inherits from CSharpSyntaxRewriter. With this class I change my SyntaxTree. But, how can I "inject" this modified synaxtree somewhere? I mean, I have some random project in Visual Studio, and on Build, I would like all the syntax trees go through this MonitorSyntaxRewriter. Is there some option for that? Or is there some other possible workaround? (creating new solution...). I just don't want my *.cs files being changed in the project. As far as I know you can't plug into the build process and rewrite the syntax trees before they're compiled and

I've noticed that the startup time for Roslyn parsing/compilation is a fairly significant one-time cost. EDIT: I am using the Roslyn CTP MSI (the assembly is in the GAC). Is this expected? Is there any workaround? Running the code below takes almost the same amount of time with 1 iteration (~3 seconds) as with 300 iterations (~3 seconds). [Test] public void Test() { var iters = 300; foreach (var i in Enumerable.Range(0, iters)) { // Parse the source file using Roslyn SyntaxTree syntaxTree = SyntaxTree.ParseText(@"public class Foo" + i + @" { public void Exec() { } }"); // Add all the

How can I get a SyntaxNode based on a line number? Else if its possible to get LineSpan of that line number then to node. You can get the span of a line from the document text. From there, you can find all nodes that intersect with the span of the line. This will return multiple syntax nodes, which you can then use your criteria to pull out the one you are looking for: static void Main(string[] args) { var code = @" using System; namespace ConsoleApplication1 { class TypeName { public int Add(int x, int y) { return x+y; } } }"; var st = SourceText.From(code); var sf = SyntaxFactory

I have been using DynamiMethod to generate the IL using method.GetILGenerator(); This works well but is of course very hard to use since you generally don't want to work with low level IL in a high level language like C#. Now since there is Roslyn I though I can use that instead. I have tried to figure out how to use Roslyn to do similar thing: generate a dynamic method and then create a delegate for it. The only way I was able to do that is to have full class like this SyntaxTree syntaxTree = CSharpSyntaxTree.ParseText(@" using System; namespace RoslynCompileSample { public class Writer {

I want to write a custom code analyzer in Visual Studio 2015 for a C# ConsoleApplication. For this reason I don't want to create a seperate "Analyzer with Code Fix" project from template, because this requires to add this analyzer in my projects as nuget package. Is it possible, to add a analyzer reference manually? I would like to reference the analyzer without nuget. If you add an analyzer as Nuget and check the content of your project, you'll see that only an <Analyzer Include="..." /> item is added. You can do the same manually. Also, you can do this in the .csproj.user file as well, so

I'm experimenting a bit with the Roslyn-CTP. Currently I'm trying to replace var with the concrete type. var i=1; should become: int i=1; Figuring out the inferred type is easy. But since this part happens in the semantic model I get a ITypeSymbol . The replacement happens in the syntax model, so I need a TypeSyntax . Since I don't want a bloated name ( global::System.Int32 ), the conversion is context dependent ( using , nested types etc.). The Visual studio version that's part of Roslyn already has this functionality in its "Simplify type name" quickfix, but looking over the samples I couldn
