RestSharp: Could not create SSL/TLS secure channel
问题 I'm trying to use RestSharp in Visual Studio 2012 Express on a fresh install of Windows 8.1. The API I'm trying to use supports only RC4-SHA for SSL. The certificate is valid. var client = new RestClient(); client.BaseUrl = "https://teststore.mybigcommerce.com/api/v2/"; client.Authenticator = new HttpBasicAuthenticator("username", "key"); var request = new RestRequest(); request.Resource = "time.json"; IRestResponse response = client.Execute(bcrequest); I keep getting an error from the client
