IT練習ノート

IT関連で調べたこと(実際は嵌ったこと)を書いています。

EC2上でC#を試してみる

価値があるとは思えませんが、環境があるとC#の文法ぐらいは勉強できるかと。

root@ip-XXX-XX-XX-XX:/home/ubuntu/download# sudo add-apt-repository ppa:keks9n/monodevelop-latest
 Here you can find the latest MonoDevelop.

monodevelop-latest package is rebuilding every time when new commits are found
at http://github.com/mono/monodevelop. Checks for commits are performed every day, so you can always have the latest version.

If you want to debug ASP.NET applications make sure that you are using your system Mono runtime ( http://i.imgur.com/SO93KJ2.png ). XSP isn't included to /opt/ Mono installation because of compatibility issues.

途中で止まる。

デスクトップ環境がないので、インストールは途中で失敗するのだと思います。

実行してみます。

コンパイル、実行はできますが、平行に実行されていないようですねぇ。。
実際はスレッド周りのプログラミングをしたかったのに残念。
