I have something like the following code
using Microsoft.WindowsAzure.Storage;
using Microsoft.WindowsAzure.Storage.Blob;
private void DownloadFile(CloudBlockBlob blobref , string fileName)
{
blobref.DownloadToFile( fileName, FileMode.Create);
}
It works most of the time
Then one day the following error occurs
Microsoft.WindowsAzure.Storage.StorageException: The operation has timed out. ---> System.TimeoutException: The operation has timed out.

The solution seems to be to re-generate the Storage Key
Is there a way to prevent this happening?

The launch settings have applicationUrl = "http://localhost:5000" & the endpoint name is not on it as suggested in other stackoverflow related issue.
Any suggestions?
The problem is not at all related to the applicationUrl. Instead I tried the EnvironmentalVariables approach with the ASPNETCORE_URLS="http://*:5000" To do this I added .AddEnvironmentVariables() with the ConfigurationBuilder. & with WebHost.CreateDefaultBuilder(), I added .UseConfiguration(config). After this little change everything works when I publish & run.

How to Solve the error.
Thank you...
I have an existing system using service fabric. Everything is fine except during a service publish the service is unavailable and any resolutions return an error.
This is expected however it would be nice if during this time instead the calls just waited or timedout. During this time my error logs will sometimes fill up with 200K lines of the same error.
I want some code like the following however where would it go?
public async Task Execute(Func<Task> action)
{
try
{
action()
.ConfigureAwait(false);
}
catch (FabricServiceNotFoundException ex)
{
await Task.Delay(TimeSpan.FromSeconds(??))
.ConfigureAwait(false);
action()
.ConfigureAwait(false);
}
}
Error:

As expected, Service Fabric have to shutdown the service to start the new version, this will cause a transient error like the one you've got.
By default, the Remoting APIs already have a retry logic built-in, from the docs:
The service proxy handles all failover exceptions for the service
partition it is created for. It re-resolves the endpoints if there are
failover exceptions (non-transient exceptions) and retries the call
with the correct endpoint. The number of retries for failover
exceptions is indefinite. If transient exceptions occur, the proxy
retries the call.
With that said, you should not require to add extra retry logic, maybe you should try adjust the OperationRetrySettings for a better handling of these retries.
If does not solve the problem, and you still want to add the logic in your code, the simplest way to handle it is using a transient-fault-handling library like Polly, something like below:
var policy = Policy
.Handle<FabricServiceNotFoundException>()
.WaitAndRetry(new[]
{
TimeSpan.FromSeconds(1),
TimeSpan.FromSeconds(2),
TimeSpan.FromSeconds(3)
});
policy.Execute(() => DoSomething());
In this sample, you do an exponential backoff between retries, if the number of calls is too big, I would recomend implement the circuit breaker approach instead.
I get an Access denied message when I try to deploy my MVC4 site with an Embedded instance of RavenDB to the new Azure Websites preview feature. The site works fine locally.
Here is how I configure Raven:
//Initialize the RavenDB Data Store
Raven.Database.Server.NonAdminHttp.EnsureCanListenToWhenInNonAdminContext(8887);
var documentStore = new EmbeddableDocumentStore()
{
DataDirectory = "~\\App_Data",
UseEmbeddedHttpServer = true,
Configuration = { Port = 8887 }
};
documentStore.Initialize();
And here is the stack trace when I browse to the site:
Access is denied

I managed to get it to work, although it is not ideal. You may notice in my original post that I am setting the UseEmbeddedHttpServer = true. This is so that I can browse to http:[MyUrl]:8081 and get the RavendDB Management Studio so that I can browse my data. For some reason, RavenDB wants to do the same kind of port check when this property is set as it does when you set the Port setting to automatic (Port=*).
I believe that RavenDB may need a fix so that it honors the Port setting when UseEmbeddedHttpServer is True and also let you set the Configuration property of the EmbeddedDocumentStore upon creation.
But in the meantime, you can truly get your MVC4 site to work with an EmbeddedDocumentStore on Azure Websites simply by specifying a port. Also, you do indeed have to use the AppSettings configuration rather than setting the Configuration property of the EmbeddedDocumentStore upon creation (like I tried to do above). This post (stackoverflow.com/questions/11529159/) shows how to do it.
Unfortunately, I still haven't found a way to run the EmbeddedHttpServer so I can use the Raven Management Studio. If I figure out how, I will post a solution here.
Hi this was answered on RavenDb on Azure Websites - Access Denied
Basically you need to configure the port in Web.config
