西澤です。今回.Net Core on Lambdaの開発環境をCloud9で用意する機会がありましたので、手順をまとめておこうと思います。
Cloud9環境の構築
まずは、環境のインフラとなるEnvironmentを作っていきます。
Nameは任意のものを指定して、Next stepをクリックします。
今回の環境は、Platform=Amazon Linuxで手順を用意しました。それ以外のパラメータはコストをかけずに必要最低限のものが良いというところだったので、ほぼデフォルトのままで設定しています。
最後に確認をしたら、Create environmentします。
しばらく待てば、ブラウザからアクセス可能な開発環境が利用できるようになります。
.Net Core 2.1インストール
インフラが整ったところで、環境を整備していきます。まずは、必要なパッケージやツールを揃えておきます。

https://aka.ms/dotnet-downloadAmazon Linux用のパッケージは存在しなかった為、下記サイトから、Lambdaのランタイムとして対応している.Net Core 2.1の最新のものから、NET Core Binaries: x64をダウンロードしました。
Amazon.Lambda.ToolsとLambdaテンプレートのインストール
Amazon.Lambda.Toolsプラグインを利用してデプロイを行う為、インストールしておきます。
cm-nishizawa.tetsunori:~/downloads $ dotnet tool install -g Amazon.Lambda.Tools
Welcome to .NET Core!

Use 'dotnet --help' to see available commands or visit: https://aka.ms/dotnet-cli-docs
Telemetry
---------
The .NET Core tools collect usage data in order to help us improve your experience. The data is anonymous and doesn't include command-line arguments. The data is collected by Microsoft and shared with the community. You can opt-out of telemetry by setting the DOTNET_CLI_TELEMETRY_OPTOUT environment variable to '1' or 'true' using your favorite shell.
Read more about .NET Core CLI Tools telemetry: https://aka.ms/dotnet-cli-telemetry
Configuring...
--------------
A command is running to populate your local package cache to improve restore speed and enable offline access. This command takes up to one minute to complete and only runs once.
Decompressing 100% 9382 ms
Expanding 100% 30250 ms
ASP.NET Core
------------
Successfully installed the ASP.NET Core HTTPS Development Certificate.
To trust the certificate run 'dotnet dev-certs https --trust' (Windows and macOS only). For establishing trust on other platforms refer to the platform specific documentation.
For more information on configuring HTTPS see https://go.microsoft.com/fwlink/?linkid=848054.
You can invoke the tool using the following command: dotnet-lambda
Tool 'amazon.lambda.tools' (version '3.2.3') was successfully installed.続けて、Amazon.Lambda.Templatesをインストールして、雛形となるテンプレートを利用できるようにしておきます。
cm-nishizawa.tetsunori:~/downloads $ dotnet new -i Amazon.Lambda.Templates
Getting ready...
Restore completed in 1.78 sec for /home/ec2-user/.templateengine/dotnetcli/v2.1.700/scratch/restore.csproj.
Usage: new [options]
Options:
-h, --help Displays help for this command.
-l, --list Lists templates containing the specified name. If no name is specified, lists all templates.
-n, --name The name for the output being created. If no name is specified, the name of the current directory is used.
-o, --output Location to place the generated output.
-i, --install Installs a source or a template pack.
-u, --uninstall Uninstalls a source or a template pack.
--nuget-source Specifies a NuGet source to use during install.
--type Filters templates based on available types. Predefined values are "project", "item" or "other".
--force Forces content to be generated even if it would change existing files.
-lang, --language Filters templates based on language and specifies the language of the template to create.

Updating code for existing function lambda_s3テンプレートから作成されたプロジェクトを無事にデプロイすることができました！こちらをベースに要件に合わせてコードを修正していけば、Lambdaの開発も捗りそうです。
ちなみに、--region指定なしでもCloud9環境が動作する環境のリージョンが指定され、--profile指定なしでAWS Management ConsoleにログインしたIAM権限の一時クレデンシャルにて動作することが確認できました！

今回はこれまであまり触れたことの無かった".Net Core on Lambda"の開発環境を作ることになったのですが、ローカル環境に依存せず共有または環境を再現できるようにしておきたかったので、Cloud9がぴったりハマりました。
どこかの誰かのお役に立てば嬉しいです。
