World is changing - .NET Native is here to stay! Sustained by .NET vNext, this is the features

Many years ago there was the COM hell. I used to work on a legacy project, where one of my colleges yell “This is DLL hell”.
Well, with the new .NET vNext (4.5.2) will change the face of the world. We could say that the history of programing is now changing. With the features from vNext and the new compiler called Roslyn you can do anything you want. For example you can change the compiler implementation, write your own compiler over it and many more.
The feature that impresses me the most was saw called .NET Native. Even if now we have support only for Windows Store, we should expect in the future to have support of this feature for all platforms.
So, what is .NET Native?
It is a new kind of compiler for .NET. The code is compiled directly to specific machine code. No more JIT and other layer of abstraction. You get what you need for your machine, extremely optimized for the specific hardware (X86, 64b, ARM). The existing CLR was optimized and refactored.
Yes, you have the C++ performance from an application that was written in C#. This is so cool. Keep in mind that this feature in combination with other new features from .NET vNext will change the way how we wrote code (M2M era).
Because the generated code is native code, that is already optimized for that specific hardware architecture, the performance is improved with around 60% and if I understood well, the memory footprint (can be) is reduced with ~30%.
Remark: The dynamic code execution, that already exist will not be removed. It will exist in parallel with the new one (.NET Native - static).
The new code that is generated doesn’t depend on the CLR that is installed on the machine. Because of this we don’t need the CLR when we run an application compiled as Native. Also, .NET is not required anymore on the client machines (we have a self-contained native compiled code in the end). Yes! Sounds good, first step to write in C# for any kind of platform and OS….. Sounds good.
 In this moment vNext team seems to be at Alpha version. I looking forward to a new release and support for desktop and server. Also, in the embedded area interesting things will happen.


  1. Dont you think with .Net native, we are going back to the old days where there is no intermediate code and we had to bundle separate executable for different machines?
    Only thing MSFT did is they got some programmers in C# who cannot think about any other language.

  2. Probably, the run-time performance will be improved a little bit. However, that's not enough.
    Once I had to deal with C++ code ported from Java by... Java programmers. It looked like Java with C++ syntax and was a (performance) disaster.
    Definitely, a program written in C# will never achieve the performance of a program well written in C++.

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:

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.

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…
