Visual Studio Online Test

I have tested C# compilation under VS Online.

This kind of paid products is not for me. As a developer, I build on a local machine and I want to be offline and not always connected. More, I don’t want to pay for and IDE and a free compiler.

Microsoft’s UI development model

The future of graphic world (UI) at Microsoft is called WinUI. WinUI are the XAML controls of Windows 10. They’re made of C/C++.

Windows 10 makes extensive use of them and offers them (finally) full access to everyone: NET, C++, Win32.

Microsoft is committed to C++. Windows too. Microsoft makes its software in C/C++ because It’s fast and efficient. Do you understand my innuendo? On the Microsoft site, if you are looking to do software development, you are referred to .NET by default. I ask the question: but why?

Microsoft doesn’t. Why would I? Microsoft is no longer in dog-fooding as before. There is an internal discourse and an external discourse.

Internally, there is no debate, we do almost everything (90%) C/C++. Windows, Office, Edge, etc.

Externally, we only promote .NET, the web, JS/TS, Angular and python!

Where I laugh is that Microsoft evangelists who spend their time taking pictures of their hamburger meal on twitter know nothing about the native world and there is a problem for example, on WinUI. There is no one left to explain the real Microsoft, the one from the inside.

On WinUI, you have to promote XAML Islands, Controls in C++ and how to explain how to mix it with MFC and Win32 controls for example. Result: nothing. There’s no one who knows how to do it.

As an MVP, I’m going to focus on that. but it’s not normal for Microsoft not to fulfill its share of Learning.

Sometimes I have discussions with developers who think that Windows is made in C#???? WTF! The level of knowledge of the Microsoft company is leveled from the bottom. .NET architects believe that desktop graphics interfaces should be made in WPF. Oh, yes? Why doesn’t Microsoft do it then?

The future is C++ and .NET Core. It’s not ony .NET and C#. NET and its CLR is powered by C++.

Multiplatform development with C++

To develop multi-platform applications, there are not fifty possible choices, there is only one that is free and efficient: it’s C++.

Only the C/C++ can take advantage of the latest developments in Windows, Linux, Android and iOS SDKs because the system and its environment are made with it. The advantage of C++ is that it ‘builds on the metal’: there is no faster. It takes advantage of the software architecture of the operating and hardware systems of the latest x86, x64 and ARM processors. For forty years, C++code optimizers have guaranteed the best possible quality of code.

C, It’s the new assembler. C++, It allows the object oriented: abstractions, inheritance and polymorphism (virtual functions), overload of operators, templates. With its STL (Standard Template Library) bookstore and in conjunction with a bookstore such as Boost (, the C++ a-has a universal toolbox that handles strings, containers (collections), algorithms, I/O, threads, smart pointers, communications, etc.

Take the plunge. Install Visual C++ Windows, GCC Linux, XCode on Mac and share business code. Make rich graphical interfaces and take advantage of the best development language that’s C++.

You will tell me there are hybrid solutions like NET or Java? These solutions are a set of thousands of heavy, slow sheets that do not create world-class applications. In cars, there are Fiat 500s and Ferraris. At the same price (see cheaper), what do you take? There’s no photo…

Article for Programmez November 2019

In Issue n°234 or French magazine Programmez for November 2019, I have written an article about How to become a Microsoft Technical Expert.

Article for Programmez October 2019

In the N°233 Issue of Programmez magazine, I have written a technical article about Windows Subsystem for LInux v2 (WSL2).

How to become a Microsoft Expert ?

Through the exchanges I have with my students at THE ESGI or on the forums, the question that often comes up is “how do you become a Microsoft Expert?”. Indeed, the stack of products and technologies is so wide that we do not know where to…

I will give you my opinion and it only hires me, neither Microsoft nor my employer.

For starters there are fundamentals: an expert is not a marabout. He doesn’t read in crystal balls but books. This could be the conclusion of this article…!

Tip 1: Read, read everything, be greedy, be voracious. Whether you are a bachelor, a bachelor’s degree, a master’s degree and even an engineer. You’re lucky, the technical works all exist in PDF format and are easily accessible live (I never said you had to go on but the idea is there) or on torrents … Use the “try before buy” Pattern: if you like a book, you buy it.

In the Azure, Windows world, there are many free books at Microsoft Press: see Look for example at the following books:

.NET microservices: Download .PDF
Docker – Microsoft: Download
Enterprise Application with Xamarin Forms: Download
The ideal is to know how to create an application architecture that looks like this:

The PDF on microservices explains this. From there, you are up to date with the latest technologies because the eShopOnContainers sample solution implements ASP.NET MVC, Docker, Azure, back-end, C- , SQL Server, cache and NoSQL, etc. The code source of the solution is available on Github:

The step can always be raised to be crossed at once. First, we have to start on a good footing.

Tip 2: Read the Windows V2 Architecture Guide; download here: This guide will explain the principles of architecture to achieve a good solution and a good application design. Here is the classic diagram of a layered application:

The C-language is one of the fundamentals. That is the basis of development. There are many specialized books such as:
– C 5 in a Nutshell
– C 7 Pocket Reference
– Pro C 7
– The C-Programmer’s Study Guide (MCSD)

Tip 3: If you want to be a true .NET development pro, there’s a reference book at Microsoft Press: CLR by C. It’s the Bible. Buy. He explains everything on .NET: BCL, JIT, garbage collector, CLR, etc.

Tip 4: Pass certifications. Start with something simple: 70-483 Programming C. Then choose your course. Web, Mobile, Azure. Your choice.

Then there are no secrets: you have to practice. Microsoft makes free editions of Visual Studio 2019 available with a Windows SDK, SQL Server is also available for download or Docker image, and Windows 10 provides IIS. In short, you have everything to become a Microsoft development pro.

Will you be an Expert? I don’t know, but in any case, I’ll give you all the information to do it. To be an expert it takes between 5 and 10 years of experience and practice on a daily basis; not before.

MVP Tip: Read Windows Internals. Don’t forget that the jewel is Windows…

And Windows is made of C/C so read too: Windows via C/C

Microsoft makes all of these products in 95% C/C so if you’re curious (real experts are), find out about Windows SDK and Win32’s C/C development. Windows, Office, SQL Server, Windows Server, Chrome, VLC: everything you have on your PC is done in C/C; Don’t forget it!
