What should I do if I suspect that one of Azure Services is not available or there is a quality degradation?

This post will be short and I will try to response to the following question:
What should I do if I suspect that one of Azure Services is not available or there is a quality degradation?
Checklist:

1. Check Azure Status (https://azure.microsoft.com/en-us/status

You will be able to find in real time information related to interruption and service degradation at world wide level. All the issues and problem are reported on this page. In this way you can know if there are (known) issues on Azure.

2. Check Azure Portal for Alerts
The new portal will notified you about different issues that can appear in the system. For example when you reach a limitation of your service (throughput) you will be notified about it (before reaching it). Don't forget that you can redirect this alerts on your email.


3. Check your service instance status on Azure Portal 
 At this step you want to be sure that your service status is green and the configuration is good. I had situations when somebody reset the access configuration or change a configuration without notify all the teams that are impacted and make a double check.

4. Check Azure Audit Logs
You might be surprised to find out that you can find very useful information about what happen in the system.

5. Check your inbox (operations)
When the services that you are using  are impacted by different operations that are done on Azure, you will be notified in advance. It is simple to miss this kind of information. For example that a major update will be done on specific VMs and you might be impacted (when you have don't have redundancy).

6. Check your inbox (notifications)
It is so easy to miss an email that notifies you that you have problem with the credit card that is connected to your Azure Subscription or situations like this. I remember one time when our credit card expired and we missed the email that notified us that in the last 3m payment was not done.

7. Open a support ticket
You can any time to open a support ticket. But, before doing this you should be 100% sure that the problem is not from your side. I'm happy to say that until now all the time the issues were because of us (when Azure Status was green) and not from Azure.

In this post I didn't talked about what you can do monitor your system. That is a long and complex story that I might write in future.

You should remember to:
  • Check Azure Status
  • Check Azure Portal
  • Check your Email

ADO.NET provider with invariant name 'System.Data.SqlClient' could not be loaded

Today blog post will be started with the following error when running DB tests on the CI machine:
threw exception: System.InvalidOperationException: The Entity Framework provider type 'System.Data.Entity.SqlServer.SqlProviderServices, EntityFramework.SqlServer' registered in the application config file for the ADO.NET provider with invariant name 'System.Data.SqlClient' could not be loaded. Make sure that the assembly-qualified name is used and that the assembly is available to the running application. See http://go.microsoft.com/fwlink/?LinkId=260882 for more information. at System.Data.Entity.Infrastructure.DependencyResolution.ProviderServicesFactory.GetInstance(String providerTypeName, String providerInvariantName) This error happened only on the Continuous Integration machine. On the devs machines, everything has fine. The classic problem – on my machine it’s working. The CI has the following configuration:

Entity Framework (EF) TransactionScope vs Database.BeginTransaction

In today blog post we will talk a little about a new feature that is available on EF6+ related to Transactions.
Until now, when we had to use transaction we used ‘TransactionScope’. It works great and I would say that is something that is now in our blood.
using (var scope = new TransactionScope(TransactionScopeOption.Required)) { using (SqlConnection conn = new SqlConnection("...")) { conn.Open(); SqlCommand sqlCommand = new SqlCommand(); sqlCommand.Connection = conn; sqlCommand.CommandText = ... sqlCommand.ExecuteNonQuery(); ... } scope.Complete(); } Starting with EF6.0 we have a new way to work with transactions. The new approach is based on Database.BeginTransaction(), Database.Rollback(), Database.Commit(). Yes, no more TransactionScope.
In the followi…

GET call of REST API that contains '/'-slash character in the value of a parameter

Let’s assume that we have the following scenario: I have a public HTTP endpoint and I need to post some content using GET command. One of the parameters contains special characters like “\” and “/”. If the endpoint is an ApiController than you may have problems if you encode the parameter using the http encoder.
using (var httpClient = new HttpClient()) { httpClient.BaseAddress = baseUrl; Task<HttpResponseMessage> response = httpClient.GetAsync(string.Format("api/foo/{0}", "qwert/qwerqwer"))); response.Wait(); response.Result.EnsureSuccessStatusCode(); } One possible solution would be to encode the query parameter using UrlTokenEncode method of HttpServerUtility class and GetBytes method ofUTF8. In this way you would get the array of bytes of the parameter and encode them as a url token.
The following code show to you how you could write the encode and decode methods.
