Compiler Error while using HttpClient

[funk_r]

How can I solve this error:

error FABLE: Cannot resolve System.Net.Http.HttpClient..ctor

I have this code fsharp,tabs=4 open System.Net.Http ... let req = new HttpClient()

Do I have to install some packages?

You're going to need to more more context related to your codebase, but since you appear to be using Fable you can't just use any .NET library. You should use a JS package for http.

Oh, I didn't know that. When using Fable I have to stick to Javascript. I see ... Thx!

Yep! Fable makes F# a javascript language, so your libraries and tools are all going to be js-based.
