To use Visual Studio to edit code in the source repository for an AWS CodeStar project, you must install a version of the AWS Toolkit for Visual Studio that supports AWS CodeStar. You must be a member of the AWS CodeStar project team with the owner or contributor role.

To use Visual Studio, you also need:

An IAM user that has been added to an AWS CodeStar project as a team member.

AWS credentials for your IAM user (for example, your access key and secret key).

Sufficient permissions to install Visual Studio and the AWS Toolkit for Visual Studio on your local computer.

The Toolkit for Visual Studio is a software package you can add to Visual Studio. It is installed and managed in the same way as other software packages in Visual Studio.
