Azure Quotes - Cores per subscription at Azure Region level

Each Azure Subscription had a default quotas service limits. You can check this quotas on the following Azure page
This values are set by default and can be increased easily by creating a new support requests.
In the new portal there is even a special support request template for this kind of scenarios.
I was surprised how fast the support team responded to my requests. In under 15 minutes a part of the quotas were changed of I was contacted to confirm the change.

Core Limitation
Let's talk a little about Core limitation. The default value is 20. This means that you can have allocated maximum 20 CPU Cores (VMs, Web Roles, Worker Roles, ...). The maximum public limit is 10.000 cores, but the interesting thing will happen in the moment when you want to change this limit and you do a request for it.
You will need to specify not only the number of cores that you need (let's assume 100), but also the location (West Europe for example).

What does this mean?
It means, that on that subscription you can consume maximum 100 cores in that region and for other regions you have a limit of 20 cores. Don't forget that you can increase this limit for each region separately.
On top of this don't forget that there are two different limits for cores. One is for the classical Core Service and another one for the new ones ('Resource Manager Cores').

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 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.
