mr.Ayoub Benayache, to start with what?

Microsoft's CNTK allows you to run trained models on C# and another programming languages (https://docs.microsoft.com/en-us/cognitive-toolkit/CNTK-usage-overview).

Full train on C#:

It seems like the contributors on github are working on it, check these threads:

https://github.com/Microsoft/CNTK/issues/1967

https://github.com/Microsoft/CNTK/issues/960

There seem to be an early effort, haven't tried though: https://github.com/Lokad/cntksharp

As microsoft has a very important support to C# due to its .NET framework, I would expect to have C# bindings on CNTK soon.

There's also .NET  bindings for Google's tensorflow: https://github.com/migueldeicaza/TensorFlowSharp

You can also use Accord.net library which is very powerful tool

I think Accord.net lib is useful. You can use NuGet console in visual studio to download and install packages directly.
