public static void Main() {
// Your Google Cloud Platform project ID
string projectId = "YOUR_PROJECT_ID";
// Instantiates a client
BigqueryClient client = BigqueryClient.Create(projectId);
// The id for the new dataset

}
何これは何を意味するのでしょうか？
default credentials (e.g. Compute Engine, App Engine)
右、私の特定のGCPプロジェクトにアクセスすることはできないのだろうか？
この点はどういう意味ですかdefault credentials？
