### Issue description

**Current behavior:**

Getting Unknown Compiler option plugins when integrating ngx-admin into a Asp.net WEB API Project.
which leads to several errors for angular core modules and fails my compilation and building for the solution.

**Expected behavior:**

It should run the ngx-admin dashboard in asp.net web api enviornment
**Steps to reproduce:**

1) Create a new Asp.Net Web Api Project.
2) Cloned ngx-admin from git hub
3) copied all the required files including tsconfig, package.json etc in my project.
4) Restored the packages by right click package.json file and restore packages
5) Running the project and getting the above errors
http://localhost:52981/package.jso
http://localhost:52981/package.jsonn
