How to Install .Net 8.0 on Ubuntu

Here’s how you install the .NET SDK on Ubuntu

Install .NET 8.0 on Ubuntu

Update Package Lists:
Ensure your package lists are updated:
```
sudo apt update
```

Install .NET SDK using the Microsoft Package Repository:

Microsoft provides a package repository for .NET installations. Here’s how to set it up:

Install the HTTPS transport and the required GnuPG (GPG) key:

sudo apt install -y wget
wget https://packages.microsoft.com/config/ubuntu/$(lsb_release -rs)/packages-microsoft-prod.deb -O packages-microsoft-prod.deb
sudo dpkg -i packages-microsoft-prod.deb

Install the .NET SDK:

sudo apt update
sudo apt install -y dotnet-sdk-8.0

Verify Installation:

After installation, verify that .NET is installed correctly:
```
dotnet --version
```
This should show you the installed version of .NET, confirming that the .NET SDK is now set up.

Alternative: Use Snap

If you prefer using Snap, you can also install .NET via Snap. Note that Snap installs can be confined and behave slightly differently from apt installations. Here’s how to get it with Snap:

sudo snap install dotnet-sdk --classic

Choose the Appropriate Command

Since you’re working with .NET 8.0, ensure you’re installing the latest dotnet-sdk-8.0 or using Snap for version 8.0 specifically. After installing .NET using either of these methods, rerun your command:

dotnet ./MyApp.dll

This should successfully execute your application. Ensure that the dotnet command is accessible in your current session; you might need to restart your terminal or re-source your profile if the command is still not found.
