I installed the quantum development kit from the microsoft site:

https://www.microsoft.com/en-us/quantum/development-kit

But when I try to open one of the projects or create a Q# I get the message:

There was an error activating the remote language server, Q# Language Extension. For more details, please run devenv /log and examine ....\ActivityLog.xml file.

I ran it and found:

ERROR System.SystemException: The trust relationship between the primary domain and the trusted domain failed. at System.Security.Principal.NTAccount.TranslateToSids(IdentityReferenceCollection sourceAccounts, Boolean& someFailed) at System.Security.Principal.NTAccount.Translate(IdentityReferenceCollection sourceAccounts, Type targetType, Boolean& someFailed) at System.Security.Principal.NTAccount.Translate(IdentityReferenceCollection sourceAccounts, Type targetType, Boolean forceSuccess) at System.Security.Principal.NTAccount.Translate(Type targetType) at System.Security.AccessControl.CommonObjectSecurity.ModifyAccess(AccessControlModification modification, AccessRule rule, Boolean& modified) at System.Security.AccessControl.CommonObjectSecurity.AddAccessRule(AccessRule rule) at System.IO.Pipes.PipeSecurity.AddAccessRule(PipeAccessRule rule) at Microsoft.Quantum.QsLanguageExtensionVS.QsLanguageClient.d__24.MoveNext() --- End of stack trace from previous location where exception was thrown --- at System.Runtime.CompilerServices.TaskAwaiter.ThrowForNonSuccess(Task task) at System.Runtime.CompilerServices.TaskAwaiter.HandleNonSuccessAndDebuggerNotification(Task task) at System.Runtime.CompilerServices.TaskAwaiter.ValidateEnd(Task task) at Microsoft.VisualStudio.LanguageServer.Client.RemoteLanguageServiceBroker.RemoteLanguageClientInstance.d__49.MoveNext() --- End of stack trace from previous location where exception was thrown --- at System.Runtime.CompilerServices.TaskAwaiter.ThrowForNonSuccess(Task task) at System.Runtime.CompilerServices.TaskAwaiter.HandleNonSuccessAndDebuggerNotification(Task task) at Microsoft.VisualStudio.Threading.ThreadingTools.d__12.MoveNext() --- End of stack trace from previous location where exception was thrown --- at System.Runtime.CompilerServices.TaskAwaiter.ThrowForNonSuccess(Task task) at System.Runtime.CompilerServices.TaskAwaiter.HandleNonSuccessAndDebuggerNotification(Task task) at Microsoft.VisualStudio.LanguageServer.Client.RemoteLanguageServiceBroker.RemoteLanguageClientInstance.d__47.MoveNext() --- End of stack trace from previous location where exception was thrown --- at Microsoft.VisualStudio.Telemetry.WindowsErrorReporting.WatsonReport.GetClrWatsonExceptionInfo(Exception exceptionObject)

Q# Language Extension

So I have no intellisense and the *.qs files are not as Q# recognized.

Visual Studio 2017 15.9

Windows 10 1809

Any idea about this?

What language is your Windows installation in? We've never seen this error before, but we have a possible theory. – Alan Geller
@AlanGeller I have 3 environments: Working: Windows 10 English. VS 2017 15.9 English - Not Working: Windows 10 German base but with English Language pack. VS 2017 15.9 English. Windows 10 Spanish. VS 2017 15.9 English . So the two machines were it is not working have a SO base in non english language. – blfuentes
Ah -- that's consistent with our theory. I'll post here when we're able to publish a potential fix. Sorry about this! – Alan Geller
@AlanGeller Thanks!. In the meantime I can continue using VS Code. – blfuentes

We have posted a new version of the Visual Studio extension (0.3.1811.1501) which we believe should fix the problem. Do you mind updating the extension and giving it a try?
