I'm using the following code to upload a test file to the ADLS. I keep getting a null reference error but I can't figure out what is null and what is being referenced. I keep trying to comment out parts of the line to find out at what point it becomes null with no success.

var creds = new ClientCredential(CLIENTID, CLIENTSECRET);
            var clientCreds = ApplicationTokenProvider.LoginSilentAsync(TENANT, creds).Result;
            using (DataLakeStoreFileSystemManagementClient adlsFileSystemClient = new DataLakeStoreFileSystemManagementClient(clientCreds))
            {
                var g = adlsFileSystemClient.FileSystem.UploadFile(_adlsAccountName, "test.txt", "/test.txt", threadCount: 1, resume: false, overwrite: false);
            }

Add a language tag to your question. If you're in Visual Studio you should be able to debug and hover of each variable to determine which is Nothing. – Andrew Mortimer Aug 08 '18 at 13:36
Ok thanks, I added the tag. I will try the hover thing. – Mingyao Xiao Aug 08 '18 at 13:44
You should be able to tell from the exception which line it occurred on, and include that information in the question. – Richardissimo Aug 08 '18 at 14:35
