Can Go Applications Integrate with C# DLLs Using go-dotnet?

Integrating C# DLLs in Go Applications

Can a .NET DLL be Incorporated into Go Applications?

While C# DLLs (dynamic link libraries) are commonly used in C# applications, integrating them into Go has been a challenge. However, advancements have been made in this area.

Overcoming the Incompatibility of C# and Go DLLs

The fundamental difference between C# and Go DLLs is in their underlying structures. C# DLLs follow the .NET Common Intermediate Language (IL), while Go DLLs operate on a lower-level format.

Utilizing Interoperability Projects

To bridge this compatibility gap, a project known as "go-dotnet" has emerged on GitHub. This project provides capabilities for creating and using .NET assemblies from within Go programs.

Example of Integrating a C# DLL in Go

Here's an example demonstrating the integration of a C# DLL containing a simple addition method:

package main

import (
    "fmt"

    dotnet "github.com/matiasinsaurralde/go-dotnet/pkg"
)

func main() {
    assembly, err := dotnet.LoadAssembly("MathForGo.dll")
    if err != nil {
        panic(err)
    }

    result, err := assembly.Call("Add", []interface{}{2, 3})
    if err != nil {
        panic(err)
    }

    fmt.Printf("Result: %v", result)
}

Conclusion

Through the use of the "go-dotnet" project, developers can now leverage C# DLLs within Go applications, enabling them to take advantage of existing .NET libraries and extending their capabilities.
