I am creating a Code Fix that changes this: if(obj is MyClass) { var castedObj = obj as MyClass; } into this: var castedObj = obj as MyClass; if(castedObj != null) { } This means I have to do 3 things: Change the condition in the if statement. Move the casting right above the if statement. Remove the statement in the body. So far, all my attempts have stranded me at getting at most 2 of these things to work. I believe this problem occurs because you basically have 2 syntax nodes on the same level. As such, making a change to one of them invalidates the location of the other one. Or something

I have a custom msbuild task with this command: var workspace = Workspace.LoadStandAloneProject(csprojPath); When I run it, it throws the following error: System.InvalidCastException was unhandled by user code Message=Unable to cast transparent proxy to type 'Roslyn.Utilities.SerializableDataStorage'. Source=Roslyn.Services StackTrace: at Roslyn.Utilities.RemoteServices.CreateInstance[T]() at Roslyn.Services.Host.TemporaryStorageServiceFactory.CreateService(IWorkspaceServiceProvider workspaceServices) at Roslyn.Services.Host.WorkspaceServiceProviderFactory.Provider.c__DisplayClass7.b__4() at

Let's say I have an enumeration of all currencies: public enum CurrencyType { /// <summary> /// United Arab Emirates dirham /// </summary> [EnumMember] AED = 784, /// <summary> /// Afghan afghani /// </summary> [EnumMember] AFN = 971, /// <summary> /// Albanian lek /// </summary> [EnumMember] ALL = 008, ... } VS 2015 code analysis keeps complaining about 100 violations of CA1709 for every individual member. This is an useful rule by itself, and I do not want to disable it; yet it is of not much help in this specific case, as CurrencyType is public and is used in a whole lot of other projects.

After installing VS 2015, running csc.exe from command line causes this message to be displayed to console: This compiler is provided as part of the Microsoft (R) .NET Framework, but only supports language versions up to C# 5, which is no longer the latest version. For compilers that support newer versions of the C# programming language, see http://go.microsoft.com/fwlink/?LinkID=533240 The link redirects to Roslyn's repository at GitHub. So, is the a way to run "compilers that support newer versions" (Roslyn) from command line? It sounds like your path is inappropriate, basically. If you open

Back at the PDC in 2008, in the C# futures talk by Anders Hejlsberg he talked about rewriting the C# compiler and providing a "compiler as a service" I certainly got the impression at the time that they were targeting the C# 4.0 timeframe for this.... Well, does anyone know what the state of this is? it doesn't seem to be there in the CTP and there is almost no information on the WEB apart from links to the 2008 PDC session video (roughly an hour in). Has this initiative gone dark? Certainly not C# 4.0. We are just finishing up the last few bug fixes for C# 4.0. This direction for the toolset

For example I have class Foo: INotifyPropertyChanged { public event PropertyChangedEventHandler PropertyChanged; public int Bar {get;set;} } Can I get the Foo class AST and rewrite Bar, in compile time, to public string Bar { get { return this.bar; } set { if (value != this.bar) { this.phoneNumberValue = value; PropertyChanged(this, new PropertyChangedEventArgs("Bar")); } } } . Compile time re-writing isn't directly supported by Roslyn today, but syntactic and semantic transformations definitely are. In fact, take a look at the "ImplementNotifyPropertyChanged" sample included in the CTP to see

There are a bunch of related questions on this, though most of the answers define Roslyn and/or provide a "fix" to some issue ( exe , with hosting providers, etc.) What I can't seem to track down is the "why" and "what for" (perhaps only in the context of ASP.Net MVC/Web API) in /bin/roslyn . I ran in to similar issues (hosting - .exe restrictions, support for 4.6 , etc.) and my "fix" was to "just deploy to Azure" (of course everything works without a hitch). But really, this doesn't answer: why are they needed? does this mean that the they are used for runtime compilation (my brain points to
