System.PlatformNotSupportedException

[Grigori Rasputin]

Hi, guys. I'm a beginner coder. I started learning C# some months ago. I use Linux Mint 21 and Visual Studio Code.
The thing is that when coding a console app I tried to use this line

Console.SetWindowSize(100, 50);

but I got this compiling error

Unhandled exception. System.PlatformNotSupportedException: Operation is not supported on this platform.

.
What is the problem here? What should I do to fix it?

I believe C# requires Visual Studio and the .NET platform. Until recently this was available only on Windows and not possible on Linux. But recently Ubuntu and Microsoft made a deal to get .NET working on Ubuntu: https://ubuntu.com//blog/install-dotnet-on-ubuntu

I tried dotnet on Mint and basic web application runs on dotnet.

I guess that you are simply trying to use a function that is unavailable on the current platform, in this case Linux.
.NET is a cross-platform product and as such restricted by what the current OS provides. It might work if you tried to run the same code on Windows or macOS. On the other hand, you could possibly find a function that would only work on Linux.

By the way:
.NET (previously .NET Core) has been available for Linux for a number of years and has been provided as a separate package.
See https://en.wikipedia.org/wiki/.NET.

Recently dotnet 6 has been fully ported to Ubuntu and Mint.

Hi.
I have installed the latest version of dotnet and it works fine (otherwise I guess I couldn't compile my vscode C# code.
Yet it doesn't seem to solve my issue

Thanks for your reply. I'll read the article.
Btw, if it is a OS-related issue, do you think that coding on a multiplatform programming language such as Java would solve the problem?

The documentation. I feel all the features in dotnet 6 do work on Mint.

Look at this page: https://docs.microsoft.com/en-us/dotnet ... ew=net-6.0
It clearly says that you will get exception PlatformNotSupportedException if the platform is NOT Windows.
