How to import a DLL in Clojure CLR?
Raw
dll-import-in-clojure-clr.md

I can start the Clojure CLR REPL with the latest Clojure release I obtained from Sourceforge:

$ mono Clojure.Main.exe
Clojure 1.9.0
user=>

And then when I enter:

(assembly-load-from "full-path-to/Xamarin.UITest.3.0.0/lib/net45/Xamarin.UITest.dll")

I get:

#object[MonoAssembly 0x4f7758b3 "Xamarin.UITest, Version=3.0.0.0, Culture=neutral, PublicKeyToken=null"]
user=>

But then when I try to import Xamarin.UITest like this:

(import 'Xamarin.UITest)

I get:

Bad type
NullReferenceException Object reference not set to an instance of an object  clojure.lang.Util.NameForType (:0)

Looking at this thread in Clojure CLR mail list, the user seems to have succeeded in importing his DLL after requiring additional libraries:
