Microsoft’s Linux-friendly approach to C# scripting on the horizon of .NET 10

Microsoft Redefines Linux Interoperability with a New C# Scripting Method for .NET 10

In 2025, the technology ecosystem will undergo a major transformation, marked by Microsoft’s stated desire to strengthen its ties with Linux. The company is moving toward a more open approach, aiming to simplify the development and management of C# scripts on Linux systems. The innovations announced around .NET 10 build on previously overlooked guidelines that pave the way for more intuitive and accessible methods, particularly for the developer and systems engineering community. This transition, more than a technical evolution, symbolizes Microsoft’s desire to adopt a collaborative and open source strategy to boost its development environment.

Microsoft’s Strategy to Make C# Scripting More Accessible and User-Friendly on Linux

Microsoft's Strategy to Make C# Scripting More Accessible and User-Friendly on Linux

Developing simpler methods to run C# on Linux is part of Microsoft’s openness. The company recently introduced a new approach for running C# files directly from the command line using familiar syntax. The key lies in the introduction of pre-built directives, ignored by the compiler, which facilitate code management without requiring the creation of complex projects. This represents a major breakthrough for cross-platform development.

Key features of this innovation include:

  • Elimination of tedious steps: No more complicated compilation processes and management of large solutions.
  • Ease of use: Launch a C# script with a direct command such as dotnet run hello.cs or simply ./hello.cs on Linux.
  • Integration of a new preprocessor: Using a hashbang directive like #!/usr/bin/dotnet run to designate the interpreter.
  • Easy package import: Adding directives like to quickly load libraries.

This new paradigm is primarily aimed at beginners, making it easier for them to learn C# on Linux. But it also represents a step forward for experienced developers looking for speed and flexibility. The community expects a real shift in the way scripts are written and executed, with a clearer convergence between Windows and Linux.

The Historical Context and Progress of C# Scripting Compared to Other Languages

C# scripting is not completely new: it has existed for over ten years, with tools such as PowerShell on Linux and third-party solutions like CS-Script. However, until now, its use has been primarily efficient in Windows environments, with limited compatibility on Linux.

The real revolution on the horizon with .NET 10 could come from this new approach, which brings the philosophy of dynamic languages ​​like Python, Go, or Rust closer together, while retaining the power and structure of C#. The differentiation lies in its simplicity: being able to write a simple .cs file and run it without complexity or additional dependencies.

Old Method New .NET 10 Approach
Using Complex Projects Direct Execution via Simple Files
Long Commands like csc Single Command dotnet run
Limited Support on Linux Enhanced Interoperability, with Specific Directives

This progress is part of a logic of friendly competition with older but very popular scripting languages. The C# developer community sees this evolution as an opportunity to combine simplicity, performance, and cross-platform compatibility.

Concrete implications for development and the open source community

Concrete implications for development and the open source community

The ability to run a C# script in seconds is a game changer for rapid development, prototyping, and even self-learning. By making technology more accessible, Microsoft hopes to revitalize its ecosystem, particularly among young developers and technology startups.

This simplification movement also has a strong community reach: forums, universities and companies are collaborating to optimize the integration of this new method. The open source community is particularly excited because it makes it easier to adopt NET and C# outside of Microsoft’s traditional walls.

  • More flexibility for open source projects : the ability to write and execute C# in script mode without complex configuration.
  • Promote the integration of Linux tools : especially with distributions like Ubuntu or Fedora.
  • Recover talents : by offering a new and user-friendly platform, even for those who come from other languages.
  • Automate server management : by creating fast and efficient scripts.

In addition, this increased compatibility with Linux opens up new perspectives for artificial intelligence projects, particularly with the integration of Microsoft modules such as Copilot. The objective is to make Microsoft a key player in the world of cross-platform development.

Impact on the community Concrete examples
Massive adoption of C# scripting Creation of small tools, workflow automation, student training
Better interoperability Merging Windows/Linux workflows
Accelerated innovation Rapid tests, immediate prototypes

The challenges and limitations of Microsoft’s user-friendly approach to Linux for C#

Despite the promising progress, this new Microsoft strategy is not without challenges. Compatibility, even enhanced, still faces certain limitations, particularly regarding the performance and stability of live interpretation on Linux. The first versions, such as that of preview 4 of .NET 10, show a delay in terms of speed of execution, which should nevertheless improve with future updates.

Another obstacle lies in the fragmentation of the Linux ecosystem. With its multiple distributions, each with its own particularities, ensuring uniformity of behavior remains complex. The community must also continue to collaborate to ensure backward compatibility and integration with other open source tools.

  • Performance still room for improvement, especially for large scripts or critical applications
  • Limited support for some less popular Linux distributions
  • Learning required to master the new syntax and directives
  • Risks of ignoring guidelines, which could complicate long-term maintenance

Despite these challenges, the desire is clearly displayed: to make this new method a standard for C# scripting on Linux, while maintaining compatibility with existing tools.
