Closed sharpninja closed 12 months ago

sharpninja commented 3 years ago

When writing to the Console on Ubuntu 20.04 from the latest Dotnet Core 5.0 SDK Snap Package, System.UnauthorizedAccessException: Access to the path is denied. is thrown.

You can find affected code at sharpninja/FizzBuzz (look in any of the Dotnet projects under src) and compiled binaries.

Regression?

I do not know if the problem previously existed.

@sharpninja are you able to repro this consistently? Could you please verify installing .NET with a method other than snap? How do you start the process, are you redirecting the standard output?

sharpninja commented 3 years ago

Yes, it happens every time. That GitHub repo has five different .Net Projects (3x C#, 1x F# and 1x VB.Net) that exhibit the same behavior.

Edit: I will try to install via the install_dotnet script tonight and test that way.

Hi @sharpninja

I've taken a look at the example that you have provided and I can't find a reason why it would be throwing.

May I ask how exactly do you run the app? Which terminal are you using? How is the dotnet process being started? Is the input reditected? Is there a script that I could run to repro it?

Thanks, Adam
