I had to upgrade from Windows Azure 1.7 to 2.1. The only change in code I had

blob.UploadFromFile(tempImage);
to
blob.UploadFromFile(tempImage,FileMode.CreateNew);

However I am getting the following error: "Combining FileMode: CreateNew with FileAccess: Read is invalid."

Here is my code below (I added the "blob.OpenWrite();" just to try). Any ideas why I am getting this error?

  string blobUri;



        /*var acct = CloudStorageAccount.FromConfigurationSetting("ImagesConnectionString");*/



        var setting = CloudConfigurationManager.GetSetting("ImagesConnectionString");

         var acct = CloudStorageAccount.Parse(setting);



        var blobClient = acct.CreateCloudBlobClient();

        var container = blobClient.GetContainerReference(RoleEnvironment.GetConfigurationSettingValue("ContainerName")); //.GetContainerReference("ContainerName");

        container.CreateIfNotExists(); //CreateIfNotExist



        var perms = container.GetPermissions();



        //upload blob image

        LocalResource local = RoleEnvironment.GetLocalResource("tempImages");

        string tempSlideImage = local.RootPath + mySlideName;

        myImage.Save(tempSlideImage);            



        CloudBlockBlob blob = container.GetBlockBlobReference(myImageName);

        blob.Properties.ContentType = "image/jpeg"; //photoToLoad.PostedFile.ContentType; //blob.Properties.ContentType = photoToLoad.PostedFile.ContentType;



        blobClient.ParallelOperationThreadCount = 3;

        blob.OpenWrite(); //this was added after the migration

        blob.UploadFromFile(tempImage,FileMode.CreateNew); //.UploadFile //blob.UploadFromStream(photoToLoad.FileContent);

        blobUri = blob.Uri.ToString();

The 2nd parameter to UploadFromFile (the FileMode) is referring to how you want to open the file on your local machine, not what you want to do with the blob in Azure storage. So to fix you can:

Change

blob.UploadFromFile(tempImage,FileMode.CreateNew); 

to

blob.UploadFromFile(tempImage,FileMode.Open); 

Also, what is tempImage? You either left out that portion of the code, or it should be tempSlideImage.

What kwill said will work, however I solved like this:

 using (var fileStream = System.IO.File.OpenRead(tempSlideImage))

        {

            blob.UploadFromStream(fileStream);

        }

In my case, the server incorrectly identifies the filename of the HttpPostedFileBase. Thus, load the inputstream, directly.

  HttpPostedFileBase file



   CloudBlockBlob blob;

    .......



   using (var fileStream = file.InputStream)

    {

        blob.UploadFromStream(fileStream);

    }
