Write Brainfuck once, call it as a C# method.
using Esolang.Brainfuck;
Console.WriteLine(BrainfuckSample.SampleMethod1());
partial class BrainfuckSample
{
[GenerateBrainfuckMethod("++++++[>++++++++<-]++++++++++[>.+<-]")]
public static partial string? SampleMethod1();
}
// output:
// 0123456789As far as we know, this is the first Brainfuck source generator for .NET.
