I start by using AspNet Core 3.0 with Dapper and I have trouble loading a partial view in the main view.

I want to load the customer contacts in a list: Customer (view) and Contacts (partial view)

Model customers:

public class Cliente
{
   (Key)
   public int CodCli { get; set; }        
   public string Nome { get; set; }
   public string Fantasia { get; set; }
   public string CNPJ { get; set; }   

  public IEnumerable Contatos { get; set; }

}

Model contacts:

    public class ClienteContato
    {
        public int FkCodCli { get; set; }
        public string Fantasia { get; set; }    
        public string Cargo { get; set; }     
        public string Nome { get; set; }    
   }

Controller:

public IActionResult Details(int CliId)
        {                  

            using (IDbConnection db = new SqlConnection(_config.GetConnectionString("DefaultConnection")))
            {
                var query = @"SELECT * from VIE_Clientes  WHERE CodCli = @CliId;
                       SELECT * FROM VIE_ClientesContatos WHERE FkCodCli = @CliId";


                var results = db.QueryMultiple(query, new { @CliId = CliId });    

                var clientes = results.ReadSingle();

                if (clientes != null)
                    clientes.Contatos = results.Read().ToList();

                return View(clientes);

            }
        }

Show the details:

@model SIGApp.Entities.Cliente

    @{
        ViewData("Title") = "Details";
    }

    
Details

    

        
Cliente
        

        

            

                @Html.DisplayNameFor(model => model.CodCli)
            
            

                @Html.DisplayFor(model => model.CodCli)
            
            

                @Html.DisplayNameFor(model => model.Nome)
            
            

                @Html.DisplayFor(model => model.Nome)
            
            

                @Html.DisplayNameFor(model => model.Fantasia)
            
            

                @Html.DisplayFor(model => model.Fantasia)
            
    
        
    
    


        Back to List
    

    

Partial view _test

@model IEnumerable


    Create New


@foreach (var item in Model) {
        
}
    

    

        

            

                @Html.DisplayNameFor(model => model.FkCodCli)
            
            

                @Html.DisplayNameFor(model => model.Fantasia)
            
            

                @Html.DisplayNameFor(model => model.Cargo)
            
            

                @Html.DisplayNameFor(model => model.Nome)
            
 

        
    
    

            

                @Html.DisplayFor(modelItem => item.FkCodCli)
            
            

                @Html.DisplayFor(modelItem => item.Fantasia)
            
            

                @Html.DisplayFor(modelItem => item.Cargo)
            
            

                @Html.DisplayFor(modelItem => item.Nome)
            
 

When executing the project, I get the following error:
InvalidOperationException: the model element passed to the ViewDataDictionary is of type
& # 39; SIGApp.Entities.Cliente & # 39 ;, but this ViewDataDictionary instance requires a model element of type
"System.Collections.Generic.IEnumerable" 1 (SIGApp.Entities.ClienteContato) ".

Thanks in advance for any help.

Thank you so much,
