Choosing the right programming language is often the first big decision a developer or IT team makes when starting a project in the .NET ecosystem. Both C# and VB.NET run on Microsoft’s Common Language Runtime (CLR), which means they share the same foundation—yet they look, feel, and evolve very differently. If you’ve ever wondered about the difference between C# and VB.NET, or asked yourself “Is VB.NET still used in 2025?”, this blog is here to give you the clarity you need.

Origins of C# and VB.NET

Every language has a story.

• C# was introduced by Microsoft in the early 2000s as a modern, object-oriented language tailored for enterprise applications, web solutions, and large-scale systems. With syntax influenced by C++ and Java, it quickly became the go-to choice for developers who wanted power and flexibility.
  

• VB.NET, on the other hand, was designed to help existing Visual Basic programmers transition smoothly into the .NET world. Its English-like commands made it more beginner-friendly and appealing for rapid application development.
  

So, why does Microsoft maintain both? Because each serves a specific audience: C# appeals to professional developers building scalable applications, while VB.NET still caters to legacy projects and teams who prefer simpler syntax.

Syntax and Language Style Differences:

One of the first things developers notice is the C# vs VB.NET syntax.

• C# is case-sensitive, meaning VariableOne and variableone are not the same.
  

• VB.NET ignores case, so you can write VariableOne or variableone and get the same result.
  

C# relies on braces { } to define code blocks, while VB.NET uses keywords like End If or End Sub. For many, this makes VB.NET more readable—but also more verbose.

Quick Example:

C# Code

if (x > 10) {

    Console.WriteLine(“Greater than 10”);

}

VB.NET Code

If x > 10 Then

    Console.WriteLine(“Greater than 10”)

End If

Object-Oriented Programming (OOP) Features Compared

When it comes to OOP, both languages are fully capable, but they differ in approach.

• C# shines with its strong generics, lambda expressions, and modern OOP design patterns. It’s compact, expressive, and ideal for developers who thrive on precision.
  
• VB.NET offers a more verbose approach, which can feel easier for beginners but less elegant for advanced applications.
  

Both support inheritance, polymorphism, and interfaces—but developers often find C# better equipped for handling complex enterprise-level OOP needs.

Performance and Application Use Cases:

Here’s the truth: at runtime, both compile down to Intermediate Language (IL) and execute on the CLR. So when people debate C# vs VB.NET performance, the technical difference is minimal.

That said, perception matters. The C# community often claims better optimization potential thanks to broader tooling, libraries, and frameworks.

Use Cases:

• C#: enterprise software, cloud apps, ASP.NET websites, Unity game development.
  
• VB.NET: legacy desktop apps, internal business tools, projects where a simple learning curve matters.
  

Community, Support, and Future Outlook:

When deciding on a language, community support is as important as syntax.

• C# has a massive global community, constant updates, and resources ranging from Stack Overflow to Microsoft’s latest .NET releases.
  
• VB.NET is in decline. New tutorials are rare, developer communities are shrinking, and its future on Microsoft’s roadmap is uncertain.
  

So, is VB.NET still used? Yes—but mostly in legacy systems where rewriting everything in C# would be too expensive. New projects are overwhelmingly leaning toward C#.

When to Choose C# vs VB.NET?

Here’s the practical decision framework:

• Choose C# if you want modern development, scalability, cross-platform compatibility, and future-proof career opportunities.
  
• Choose VB.NET if your company already has thousands of lines of VB.NET code or if your team prefers a simpler, more readable syntax.
  

Interestingly, some developers even explore C# to VB.NET converters (and vice versa) to reuse existing code bases. While this can save time, most experts recommend migrating to C# for long-term sustainability.

Conclusion: Making the Right Decision as a Developer

Both C# and VB.NET were created for the .NET ecosystem, and both get the job done. But the market, community, and Microsoft’s focus make one thing clear: for most developers, C# is the smarter long-term investment.

Still, if you’re maintaining legacy systems or have business applications heavily built in VB.NET, sticking with VB might make sense—at least for now. Just keep in mind that tools exist to help with C# to VB.NET migration or vice versa if the need arises.

FAQs

Is VB.NET still used in 2025?
Yes, though its usage is mainly in legacy business applications. Most new projects adopt C#.

Which is easier to learn, C# or VB.NET?
VB.NET is simpler for beginners, but C# is the better choice for long-term development.

Are there performance differences between C# and VB.NET?
Not significantly. Both compile to CLR, though community perception favors C#.

Should I migrate from VB.NET to C#?
Yes, if you want access to modern tooling, stronger community support, and future-proof apps.
