Error to use a function inside a DLL - Unresolved import function call

 

I created a dll called spintaxx.dll in C# using Visual Studio 2017, my project there was compiled correctly  using RGiesecke.DllExport to access externally. The problem is when I create my EA and try to call the function it doesn't work, say that the function cannot be find.

Error in ExpertAdvisor tab.


Error in a dll dependent of the dll that I created.

Anyone already have this problem and can help me?
