Hi,

Please try:

public void Salvar(string data)
{
    Model.MyType obj = JSON.Deserialize<Model.MyType>(data);
}

I solved the problem. Thx Daniil.
The problem is:

The tag

<add name="JSONAsmx" type="JsonHttpModule, App_Code"/>

has missed in web.config. Sry, My mistache.

Thx again Daniil. Can close this.
