I’ve been programming for around 14 years.
During all that time, I never really cared about certificates.
I learned by building things.
Web applications. Business software. APIs. Automation tools. Desktop applications. Projects that broke, projects that worked, and projects that forced me to learn things I thought I already understood.
For years, that was enough for me.
Then I decided to try something different.
I gave myself three days to prepare for the Microsoft Applied Skills: Get started with classes, properties, and methods in C# assessment.
I passed.
And it made me reconsider my position on technical credentials.
I also turned the notes and exercises I personally used during those three days into a compact preparation resource for developers who want to follow a similar approach:

But the interesting part isn’t the product.
It’s what happened during those three days.
Why I ignored programming certificates for so long
My reasoning used to be pretty simple:
If I can build software, why do I need a certificate telling people that I can build software?
And there is still some truth to that.
A credential cannot replace experience.
It cannot replace the hours you spend debugging a problem that makes absolutely no sense until you finally find the tiny mistake causing it.
It cannot replace shipping software.
And it definitely cannot turn someone into an experienced developer overnight.
So for most of my career, certificates were completely out of the equation.
I based my argument on practical experience.
Build things. Solve problems. Learn what you need. Repeat.
But there was a weakness in that argument that I hadn't paid enough attention to.
Experience and proof are not the same thing
You might know C#.
You might have used it professionally for years.
But someone looking at your LinkedIn profile, resume, portfolio, or job application doesn't automatically know that.
They have to take your word for it or spend time examining your work.
A credential gives them another signal.
Not proof that you're an amazing developer.
Not proof that you're better than somebody without one.
Just another piece of evidence.
That distinction changed the equation for me.
Microsoft describes Applied Skills credentials as a way to demonstrate practical ability through lab-based assessments involving real tasks rather than relying entirely on traditional knowledge questions.
That caught my attention.
So I decided to test one.
I chose C# classes, properties, and methods
I started with:
Microsoft Applied Skills: Get started with classes, properties, and methods in C#
It's a beginner-level credential focused on fundamental object-oriented C# skills. Microsoft says the assessment evaluates your ability to:
- create classes, objects, and types
- work with properties
- work with methods
- call properties and methods
The assessment itself is an interactive lab, and Microsoft currently gives candidates up to two hours to complete it.
You can see the official credential and assessment here:
I already had years of .NET experience, so my goal wasn't to learn C# from zero.
My goal was different:
Could I organize what I needed to revise, hammer on my weak areas, practice them, and pass the assessment in three days?
So I started preparing.
The three-day preparation
I didn't want to spend three days passively reading documentation.
I wanted something I could actually work through.
So I built my own preparation folder.
As I revised, I organized the concepts I needed, wrote examples, practiced the syntax, and focused on the areas covered by the assessment.
Classes.
Objects.
Constructors.
Properties.
Access modifiers.
Nullable properties.
Methods.
Return values.
Method overloading.
Static classes and members.
Object initializers.
And the small details that are incredibly easy to understand when reading code but surprisingly easy to forget when you have to write the code yourself.
That last part mattered.
There's a big difference between:
“Yeah, I know what that is.”
and:
“Give me an empty editor. I can implement it.”
Microsoft's own study guide reflects that practical scope, covering class creation, property access, nullable/default values, methods, overloads, static classes, object instantiation, and calling methods and properties.
So I practiced.
Then I took the assessment.
And I passed.
The certificate wasn't actually the biggest benefit
This was the counterintuitive part.
I started because I wanted the credential.
But the preparation itself ended up being just as valuable.
When you've programmed for a long time, you accumulate knowledge from everywhere.
Documentation.
Stack Overflow.
Projects.
Coworkers.
Bugs.
Frameworks.
Old codebases.
New codebases.
And increasingly, AI tools.
You can become productive while still having little gaps in fundamentals that you haven't explicitly revisited in years.
Preparing for an assessment forces you to organize that knowledge.
You stop saying:
“I basically know this.”
You have to find out whether you actually do.
That exposed a few things I needed to hammer on.
And that's useful.
Certificates won't replace a portfolio
I still wouldn't tell a developer to collect certificates and neglect everything else.
If I had to weigh a credential against the ability to actually build software, practical ability would take precedence.
Build projects.
Write code.
Learn debugging.
Understand databases.
Learn APIs.
Understand how applications are structured.
Break things.
Fix them.
Ship something.
But it doesn't have to be projects OR credentials.
You can have both.
A project demonstrates what you've built.
Experience demonstrates what you've done professionally.
A credential gives you an external signal that you've demonstrated a defined set of skills.
Those things can complement each other.
Credentials can also give your learning a finish line
This might be my favorite benefit.
“Learn more C#” is a terrible goal.
Where do you stop?
What exactly do you study?
How do you know when you've learned enough?
An assessment gives the learning process boundaries.
You have a defined skill set.
You prepare.
You practice.
You take the assessment.
You pass or you discover where you're weak.
Either outcome gives you information.
Instead of endlessly consuming tutorials, you're working toward something concrete.
For me, that created momentum.
I got the first credential.
Now I want to keep rolling.
Does a Microsoft Applied Skills credential guarantee you a job?
No.
And I wouldn't sell that idea to anyone.
A hiring decision involves experience, communication, technical ability, location, salary, the company, the role, competition, and sometimes plain luck.
One credential doesn't erase that.
But job hunting is rarely about finding one magical thing that gets you hired.
It's about compounding signals.
Your experience.
Your projects.
Your portfolio.
Your GitHub.
Your ability to articulate technical decisions.
Your credentials.
Your communication.
One more credible signal can be useful.
Microsoft itself positions Applied Skills as Microsoft-verified credentials designed to demonstrate specific practical skills, including through interactive, lab-based assessments.
That's the way I'm looking at them now.
Not as a replacement for experience.
As another layer of proof.
Would I pursue more Microsoft credentials?
Yes.
That's probably the biggest change in my position.
After roughly 14 years of programming without paying much attention to certificates, I earned one and immediately understood why they can be useful.
Not because the badge suddenly makes me a better programmer.
It doesn't.
The value was the process:
Choose a skill → revise it → practice it → identify gaps → prove it → move forward.
That's a learning loop I can repeat.
And I intend to.
If you're preparing for the same C# assessment
During my three-day preparation, I created the material for myself first.
It wasn't originally some grand product idea.
It was my prep folder.
After passing, I realized someone else preparing for the exact same assessment might find it useful.
So I cleaned it up and turned it into a focused preparation resource:
C# Classes, Properties & Methods: My 3-Day Microsoft Applied Skills Prep
It follows the concepts I revised before successfully completing the Microsoft Applied Skills assessment, with explanations, C# examples, and exercises.
It's not a shortcut around learning the material.
It's the material I used to make my own revision more focused.
You can check it out here:
https://yaman95.gumroad.com/l/microsoft-applied-skills-classes-methods-properties
And whether you use my notes or prepare completely on your own, I'd recommend giving the assessment a shot if these are skills you're currently learning.
Three days ago, I had never earned a Microsoft credential.
Now I have my first one.
Time to work toward the next.
