ZCRMRestClient Winform .net Framework 4.7.2 C# Error

Hi.

Sorry for my bad english.

I'm trying to use SDK ZCRM  But ZCRMRestClient always "don't exist in the current context".
I'm using Visual studio 2019 , winform application C# with framework 4.7.2

1. I had Installed SDK With Dependance (tool, nuget management, console)
- Install-Package ZCRMSDK
-> no problem it's appear in my project references (ZCRMSDK, Mysql, Json...)

2. I had registrer my application

I had tried with app.config (config section settings / zcrm configuration)
I had tried with declaring  public static Dictionary

i have add in my program.cs "using ZCRMSDK;"


I had tried in C# console application fw 4.7.2
I had tried in C# Windows services fw 4.7.2

But using ZCRMSDK; always appear doessn't existing,  ZohoOAuthClient Too.


Thanks a lot for your answer.
