Example of invoking Rust code from C#

Sample code for the blog post Calling Rust code from C#.

Prerequisites

1. Install Rust
2. Install .NET SDK
3. Install uniffi-bindgen-cs

• use version 0.2.0 to match the uniffi version we will use in the Rust code
• cargo install uniffi-bindgen-cs --git https://github.com/NordSecurity/uniffi-bindgen-cs --tag v0.2.0

Building

Build everything

build.sh

or first build the Rust library manually

cd rust-lib
cargo build

followed by building the C# host

cd csharp-host
dotnet build

Running

Now you can invoke the C# host, which calls into the Rust library

cd csharp-host
dotnet run
