preamble
When we need to test code snippets quickly, it is common practice to launch Visual Studio or use an online code editor. However, Visual Studio can be slow to start and consume a lot of system resources, while online editors may encounter syntax support limitations or network latency issues.
To solve this problem, we recommend a lightweight native C# execution tool - theCSharpRepl. It can provide an instant, convenient environment that can quickly validate code ideas without having to wait for the IDE to start and without the limitations of a network connection.
CSharpRepl has the advantage of being small, fast to start, and supports a wide range of C# syntax features, making it ideal for instantly being able to see the effects of code and helping us to quickly validate textual issues.
Whether you're a beginner or a power user, CSharpRepl can be an ideal platform to run your code and help you learn and work more efficiently.
In short, CSharpRepl is a practical alternative that simplifies the process of testing C# code and lets you focus on the programming itself without having to struggle with the limitations of the tool.
Introduction to CSharpRepl
CSharpRepl is a C# interactive REPL (Read-Eval-Print Loop) tool running in a .NET Core environment , maintained by waf open source on GitHub .
The REPL environment allows developers to interactively execute C# code, making it ideal for experimentation, prototyping, learning language features, and rapid scripting.
CSharpRepl Features
1, instant feedback: After entering the code, CSharpRepl immediately executes and displays the results, without having to compile the entire project.
NET Core Compatible: Fully compatible with .NET Core, which means it can run on multiple operating systems, including Windows, macOS, and Linux.
3、Code Completion and Intelligent Sensing: Provide automatic code completion and intelligent sensing functions to improve coding efficiency.
4, code reuse: variables and methods defined in the REPL session in the subsequent command line input is still available to facilitate code reuse.
5, file import: you can import the code in the local file , easy to test and debug code fragments in the REPL environment.
6, custom configuration: the user can adjust the behavior of the REPL as needed, such as setting the default set of references, preloaded assemblies and so on.
7, support for IL (intermediate language) disassembly, including debugging and release mode.
8. Support OpenAI integration.
Installation and use
1. Install CSharpRepl
Via NuGet Package Manager
If the .NET SDK is already installed, you can install CSharpRepl globally from the command line using the following command:
dotnet tool install --global CSharpRepl
Source Code Compilation
To compile CSharpRepl using source code, download the source code from GitHub and build the project using the .NET CLI or Visual Studio.
2. Start CSharpRepl
Once the installation is complete you can start the CSharpRepl tool by entering the following command at the command line
3. Use CSharpRepl
Type and execute C# code, then press Enter to execute.
Install the NuGet package and reference it
