serverless create --template aws-csharp --path myService or sls create --template aws-csharp --path myService, where 'myService' is a new folder to be created with template service files. Change directories into this new folder.

2. Build using .NET CLI tools and create zip package

dotnet restore
dotnet publish -c release

pushd bin/Release/netcoreapp1.0/publish
zip -r ./deploy-package.zip ./*
popd

./build.sh runs the dotnet restore and package commands then creates the zip file to upload to lambda.

3. Deploy

serverless deploy or sls deploy. sls is shorthand for the Serverless CLI command

4. Invoke deployed function

serverless invoke --function hello or serverless invoke -f hello

-f is shorthand for --function

In your terminal window you should see the response from AWS Lambda

{
    "Message": "Go Serverless v1.0! Your function executed successfully!",
    "Request": {
        "Key1": null,
        "Key2": null,
        "Key3": null
    }
}

Congrats you have just deployed and run your Hello World function!
