V2.0.0 is only supporting full .net 4.5.2, 4.6, and 4.6.1. Once .NETStandard 2.0 is released this packaged will be updated to run using this. More detailed Examples will follow then.
ASP.Net Core full framework (4.5.2 4.6 4.6.1) Website / WebAPI Set up.

Within appsettings.json and add the following

{
 "TPJ": {
   "Encrypt": {
     "EncryptionKey": "",
     "Salt": "",
     "KeySize": "",
   }
 }
}

EncryptionKey– (Required) Key used to lock the string down so it can only be decrypted using the same key  

Salt - This size of the IV (in bytes) must = (keysize / 8).  Default keysize is 256, so the IV must be 32 bytes long. Using a 16 character string gives us 32 bytes when converted to a byte array.

KeySize - by default its set to 256 which means you need a 32byte salt key if set to 128 you need a 16byte salt or 512 you need a 64 byte salt

Example appsettings.json setup –
{
 "TPJ": {
   "Encrypt": {
     "EncryptionKey": "asdzgfh|£%^%TEGDSTEGbg54e523s",
     "Salt": "tu89gaji343t89u2",
     "KeySize": "256",
   }
 }
}

Once appsettings.json is done open StartUp.cs file and go to ConfigureServices

var settings = new TPJ.Encrypt.Models.EncryptSettings(Configuration);
services.Configure<TPJ.Encrypt.Models.EncryptSettings>(options =>
{
   options.EncryptionKey = settings.EncryptionKey;
   options.Salt = settings.Salt;
   options.KeySize = settings.KeySize;
});

services.AddSingleton<TPJ.Encrypt.IEncrypt, TPJ.Encrypt.Encrypt>();

Then using DI within asp.net core you can call IEncrypt like so

private readonly TPJ.Encrypt.IEncryption _encryption;

public HomeController(TPJ.Encrypt.IEncryption encryption)
{
 _encryption = encryption;
}

Then you might have this

public string EncryptString(string valueToEncrypt)
{
 return _encryption.Encrypt(valueToEncrypt);
}

It really is that simple you will get an encrypted string returned. To then decrypt the string call _encryption.Decrypt(encryptedValue);
