我的代码片段
var endPoint = "https:/endpoint-URI:443/";
var key = "api-Key";
CosmosClient cosmosClient = new CosmosClient(endPoint,key); // i get error here
var databaseName = "dbName";
var containerName = "containerName";
var container = cosmosClient.GetContainer(databaseName, containerName);
var upsertOrder = new
{
id = new Guid(),
Partition = "",
Ticker = "ABC"
};
var response = await container.CreateItemAsync(item: upsertOrder)
我应该能够初始化 Cosmos 客户端来访问数据
此错误与 Cosmos DB SDK 无关。 SDK 是异常根源的原因是它尝试使用
System.Configuration该错误与应用程序配置和正在使用的框架有关，
