Call the .net dlls into the golang

[Pavan Kumar A R]

Hello ,

I build the.net dlls in the target framework, which is.net-framework 2.0, and inside the.net dlls are some functions. I want to call this function in Golang. How can I call the.net function in Golang? Please help out here.

You can't call .NET functions directly from Go. Go programs and .NET have two completely different runtimes. You would need some form of inter-process communication (IPC).

Okay,  it's possible to call the C program to Golang. Because I also have the C platform dlls and the C platform dlls  we using in the cross platform mono and in the mono internally call the.net dlls function , can I use the C program dlls in Golang?  

[Carla Pfaff]

Yes, you can call C functions from Go, it's called Cgo: https://go.dev/blog/cgo

cgo command   

https://pkg.go.dev/cmd/cgo   

Cgo enables the creation of Go packages that call C code.

"try building at the command line"

That's your clue. You'll most likely get a meaningful error message on stderr, which your IDE is hiding.
