Running the console app

Problem encountered on https://dotnet.microsoft.com/learn/dotnet/hello-world-tutorial/run Operating System: windows

using Powershell ISE in Admin mode, I get this:

> PS F:\net6\myapp> dotnet run
dotnet : System.ComponentModel.Win32Exception (5): Access is denied.
At line:1 char:1
+ dotnet run
+ ~~~~~~~~~~
    + CategoryInfo          : NotSpecified: (System.Componen...cess is denied.

   at Microsoft.DotNet.Cli.Program.ProcessArgs(String[] args, TimeSpan 
startupTime, ITelemetry telemetryClient)
   at Microsoft.DotNet.Cli.Program.Main(String[] args)

Using the default command line in admin mode, I get this:

F:\>cd net6\myapp

F:\net6\myApp>dotnet run
System.ComponentModel.Win32Exception (5): Access is denied.
   at System.Diagnostics.Process.StartWithCreateProcess(ProcessStartInfo startInfo)

   at Microsoft.DotNet.Cli.Program.ProcessArgs(String[] args, TimeSpan startupTime, ITelemetry telemetryClient)
   at Microsoft.DotNet.Cli.Program.Main(String[] args)

F:\net6\myApp>

BUT, Using VS 2019 (Version 16.9.4), after opening the .csproj file, and running the project, I get this:

Hello World!

F:\net6\myApp\bin\Debug\net6.0\myApp.exe (process 17640) exited with code 0.
To automatically close the console when debugging stops, enable Tools->Options->Debugging->Automatically close the console when debugging stops.
Press any key to close this window . . .

The web instructions state that I should get the result that came with using VS 2019, from the regular commandline, run in the project directory, but this fails. Is this known Issue? If yes, is there a workaround that does not involve the IDE?

It sounds like dotnet run isn’t working from admin command prompts for you. I’m not sure why that is happening. So I asked you to try running the app without dotnet run in order to try to narrow down the issue.

dotnet run from the project folder should work, but I don’t believe dotnet run myApp.dll or dotnet run myApp.exe has ever worked.

@joeloff Any ideas here?

Following the suggestion, here’s the Build Result: PS F:\net6\myApp> dotnet build Microsoft ® Build Engine version 16.10.0-preview-21181-07+073022eb4 for .NET Copyright © Microsoft Corporation. All rights reserved.

Determining projects to restore… All projects are up-to-date for restore. You are using a preview version of .NET. See: https://aka.ms/dotnet-core-previ ew myApp -> F:\net6\myApp\bin\Debug\net6.0\myApp.dll

Build succeeded. 0 Warning(s) 0 Error(s)

Time Elapsed 00:00:01.68

I then tried to run the exe from outside of the \bin\Debug location: `PS F:\net6\myApp> cd bin\debug

PS F:\net6\myApp\bin\debug> dotnet run .\net6.0\myApp.exe`

and got this as the Result: dotnet : Couldn’t find a project to run. Ensure a project exists in F:\net6\myApp\bin\debug, or pass the path to the project using --project. At line:1 char:1

• dotnet run .\net6.0\myApp.exe

•   + CategoryInfo          : NotSpecified: (Couldn't find a...sing --project. 
   :String) [], RemoteException
    + FullyQualifiedErrorId : NativeCommandError
  
  

Next I went to the fq location, and made sure that I was in the right place: PS F:\net6\myApp\bin\debug> cd net6.0

PS F:\net6\myApp\bin\debug\net6.0> ls

Directory: F:\net6\myApp\bin\debug\net6.0

Upon seeing that I was in the right location to comply with the suggestion, I ran this: PS F:\net6\myApp\bin\debug\net6.0> dotnet run myApp.exe

And got this as a result: dotnet : Couldn’t find a project to run. Ensure a project exists in F:\net6\myApp\bin\debug\net6.0, or pass the path to the project using –project. At line:1 char:1

• dotnet run myApp.exe

Obviously this was done in PowerShell, but that is how my machine is set up.

Thoughts? Suggestions?
