I'm trying to setup an azure function that imports a blob into azure media service. But when i try to run the function in debug mode some breakpoints are never hit and then i get this error
Microsoft.Azure.WebJobs.Host.FunctionInvocationException : Exception while executing function: Functions.EncodeJob ---> System.MissingMethodException : Method not found: 'System.Threading.Tasks.Task Microsoft.WindowsAzure.MediaServices.Client.CopyBlobHelpers.CopyBlobAsync(Microsoft.WindowsAzure.Storage.Blob.CloudBlockBlob, Microsoft.WindowsAzure.Storage.Blob.CloudBlockBlob, Microsoft.WindowsAzure.Storage.Blob.BlobRequestOptions, System.Threading.CancellationToken)'. at MyApp.WebTasks.EncodeJob.EncodeJobTrigger.CreateAssetFromBlob(CloudBlob sourceBlob,CloudStorageAccount destinationStorageAccount) at C:\Source\Quickflix\MyApp.webtasks\MyApp.WebTasks\EncodeJob\EncodeJobTrigger.cs : 164 at.....(truncated due to length)
It seems the cause is this block here
// Call the CopyBlobHelpers.CopyBlobAsync extension method to copy blobs.
using (var task =
CopyBlobHelpers.CopyBlobAsync((CloudBlockBlob)sourceBlob,
(CloudBlockBlob)destinationBlob,
new BlobRequestOptions(),
CancellationToken.None))
{
task.Wait();
}
When i comment this block out i'm able to hit a breakpoint that i stuck in the method that this belongs to. When it is not commented out the breakpoint is never hit and i get this error. The exception seems to happen as soon as i step into CreateAssetFromBlob and not on the line that actually calls CopyBlobAsync. I've checked that all my nuget packages are up to date and that the version of Microsoft.WindowsAzure.MediaServices.Client.Extensions in the bin dir is the same version. The project builds fine so i'm not sure what i am missing. I'm scratching my head over why its behaving like this, am i missing something obvious?
So the project is setup as a Webapplication using this sample https://github.com/lindydonna/FunctionsAsWebProject which seems to work ok, i can debug locally and deploy to azure functions app using git.
For a more complete code snippet this is pretty much what i have

Update 1 So i updated this block/function to be async and not wait on the task but i still get the same error. Updated code looks like this.
await CopyBlobHelpers.CopyBlobAsync((CloudBlockBlob) sourceBlob,
(CloudBlockBlob) destinationBlob,
new BlobRequestOptions(),
CancellationToken.None);

This is likely caused by a mismatch on the version of the Storage SDK you're using. Can you please downgrade to 7.2.1 and retry?
