Console.BufferHeight in netcoreapp2.1 raise Exception PlatformNotSupportedException in Ubuntu

Question

I have a Console application build in dotnetcorapp2.1. It's running fine on Windows.

When trying to run on Ubuntu it raise an Exception error:

System.PlatformNotSupportedException: Operation is not supported on this platform. at System.ConsolePal.set_BufferHeight(Int32 value)

That is because This line:

     Console.BufferHeight = Int16.MaxValue - 1;

This document didn't mention the limitation that I take into account for Console.BufferHeight

Googling didn't help like this and this

What is the limitation of Console.BufferHeight (and BufferWidth) on Ubuntu?

Answer 1

I have posted this question to corefx team and submitted an issue there.

The member Console.BufferHeight is not supported on Unix. The docs didn't state the Unix specific behaviors on the Console methods/properties.

The class ConsolePal in the document ConsolePal.Unix.cs include also other NotSupported members.

A new document is created to show the PlatformNotSupportedExceptions in System.Console

I modified the code and catch PlatformNotSupportedException separate and application is running on Ubuntu without a problem.

      try
      {
         //.... do your stuff here
      }
      catch (PlatformNotSupportedException )
      {
        //log PlatformNotSupportedException 
        //noop
      }
      catch (exception ex)
      {

         //handle exception
      }

Edit
