.NET 8.0 を WSL2 Ubuntu にインストールする
まえがき
.NET 8.0 を Ubuntu 22.04 にインストールしようとしたところ、パッケージマネージャが8.0にまだ対応していない[1]ので、Microsoft パッケージ リポジトリを参照させる方法、またはMicrosoftで用意されているインストールスクリプトを使用してインストールします。
【追記】
最初はインストールスクリプトを使用したインストール方法でやっていたんですが、VSCodeが認識しなかったりしたので、Microsoft パッケージ リポジトリを追加する方法で再インストールしたら、VSCodeも認識するようになったので、一応やり方を追記します。
いろいろインストールしているので、すんなりいく人は行くと思います😫

Microsoft パッケージ リポジトリ を参照するインストール
Microsoft パッケージ リポジトリには、ご利用のバージョンの Ubuntu で現在サポートされている、または以前サポートされていたすべての .NET バージョンが含まれています。 ご利用のバージョンの Ubuntu で .NET パッケージが提供されている場合は、Ubuntu パッケージの優先順位を下げて、Microsoft リポジトリを使用する必要があります。 パッケージの優先順位を下げる方法については、「Linux ディストリビューションで提供されていないバージョンの .NET が必要です」をご覧ください。
Ubuntuのパッケージリポジトリに追加されたら、こっちのリポジトリは参照しないようにするか、優先度を下げたりする必要があるようです。たぶん。
