Valid Parameters for MSDepoly via MSBuild

We are in the process of automating our build processes with TeamCity. I had it all up and working great except I could not find the command line switch to prevent web deploy from removing existing files from the deploy target.

Until I found the following post on stackoverflow.com:

Here's a list I've compiled for my own reference, along with some of the legal values that can be used. Note that these are passed into MSBuild using the /p:<PropertyName>=<Value> syntax.

    DeployOnBuild
        True
        False
    DeployTarget
        MsDeployPublish
        Package
    Configuration
        Name of a valid solution configuration
    CreatePackageOnPublish
        True
        False
    DeployIisAppPath
        <Web Site Name>/<Folder>
    MsDeployServiceUrl
        Location of MSDeploy installation you want to use
    MsDeployPublishMethod
        WMSVC (Web Management Service)
        MsDepSvc
        RemoteAgent
    AllowUntrustedCertificate (used with self-signed SSL certificates)
        True
        False
    UserName
    Password
    SkipExtraFilesOnServer (leave existing non-conflicting files alone)
        True
        False

The property I was missing was "SkipExtraFilesOnServer". I hope this helps somebody else. I really wish Microsoft would make the documentation for msbuild more complete.
