Create Client:

public IBitrixService BitrixCreateClient()
{
      var configCredential = configuration.GetSection("Credential");
      var credential = new System.Net.NetworkCredential(configCredential["login"], configCredential["password"]);
      return new BitrixClient(
          new AuthParameters(
              new Site24(configuration["Url"]),
              credential,
              configuration["ClientId"],
              configuration["ClientSecret"])
          ) as IBitrixService;
}

Retrieve Entity (example: Crm.Contact):

var query = new Bitrix24QueryBuilder("crm.contact.list")
                    .AddSelect("ID", "NAME", "LAST_NAME", "SECOND_NAME", "EMAIL", "PHONE", "UF_CRM_1654007527292");
                    .AddFilter("NAME","Alexander") //$NAME, !NAME, >NAME
                    .Order("NAME",OrderEnum.ASC);
var response=await client.RetrieveListAsync<BitrixResponse<CrmContactAdvanced>>(query);

Retrieve all records of Entity (example: Crm.Contact):

var query = new Bitrix24QueryBuilder("crm.contact.list")
  .AddSelect("ID", "NAME", "LAST_NAME", "SECOND_NAME", "EMAIL", "PHONE", "UF_CRM_1654007527292");
var contacts = new List<CrmContactAdvanced>();
BitrixResponse<CrmContactAdvanced> response;
int next = 0;
do
{
  query.Start(next);
  response = await client.RetrieveListAsync<BitrixResponse<CrmContactAdvanced>>(query);
  contacts.AddRange(response?.result);
  next += 50;//max step 50
} while (response.next != null && response.next > 0);

Create (example: Crm.Contact):

client.CreateAsync<CrmContactAdvanced>("crm.contact.add",new CrmContactAdvanced
            {
                NAME ="loh",
                LAST_NAME="pidor"
            })

Update (example: Crm.Contact):

await client.UpdateAsync<CrmContactAdvanced>("crm.contact.update",new CrmContactAdvanced
            {
                ID= 42055,
                NAME ="loh",
                LAST_NAME="pidor"
            })

Delete (example: Crm.Contact):

await client.DeleteAsync("crm.contact.delete",42055);

You can inherit several basic entity (Crm.Company,Crm.Contact,Crm.Deal,Crm.Lead) classes (Example: Crm.Contact): <details> <summary>Example</summary>
