These are samples in C# for using the commerce APIs for Microsoft Partner Center. These CREST APIs are documented at https://msdn.microsoft.com/en-us/library/partnercenter/dn974944.aspx.

A public forum for discussing the APIs is available at https://social.msdn.microsoft.com/Forums/en-US/home?forum=partnercenterapi.

To update resources in a customer tenant or directory, an application must have a security principal. The principal can be created in every customer tenant, or can be created in the reseller tenant via a multi-tenant, native application. To ease the admistrative burden for the sample, the latter option is implemented. The steps are detailed in the prerequisite page.

The Create VM scenario will require user credentials at run-time. This user must be a member of the Admin Agents group in the reseller directory. To allow unattended operation, the sample application uses the Windows Credential Manager application to securely store the account and password of this user. It is recommended that a "service account" be created rather than storing an actual user credentials. The Credential Manager page includes steps for creating a stored credential.

The sample application has several configurable settings in the app.config file. Set the values as appropriate for your tenant.
