Loading-.net-DLL-in-Java

This repository includes CSharp(.cs), C, Java files.Here the C# DLL is loaded into Java using NativeAOT feature of .net 7. The C# DLL is first loaded into C code ,and the DLL from C code is used in Java using JNI concept. Native AOT(Ahead Of Time)compilation can be used with both Windows and Linux platforms.

Steps:

  1. Create a C# class library either in Visual Studio or Visual Studio Code

  2. Annote the functions to be exported with UnmanagedCallersOnlyAttribute.

  3. Publish the C# code,

    Static Library:  dotnet publish /p:NativeLib=Static -r win-x64 -c release //For Linux -: linux-64
Dynamic Library: dotnet publish -r win-x64 -c Releaserelease //For Linux -: linux-64

  4. Construct a C code calling the exported functions from C#.

  5. Construct a Java code with call to native functions(C functions).

  6. Compile the Java Code.

    javac -h . filename.java

  7. Include the generated headers in the C code .

  8. Compile C code to create DLL.

  9. Run the Java Program.
