Ci risiamo con questo Medium Trust di register.
Ho costruito una dll in design mode per costruire una textbox con il calndario di jquery.
Posto il codice:
using System;
using System.Collections.Generic;
using System.ComponentModel;

[Category("Appearance")]
[DefaultValue("1")]
[Localizable(true)]
public int NoOfSpaces
{
get
{
if (ViewState["NoOfSpaces"] == null)
{
ViewState["NoOfSpaces"] = 0;
return 0;
}
int intSpaces = -1;
int.TryParse(ViewState["NoOfSpaces"].ToString(), out intSpaces);
if (intSpaces != -1) return intSpaces;
else
{
throw new InvalidOperationException("invalid value");
}
}
set
{
ViewState["NoOfSpaces"] = value;
}
}
[Bindable(true)]
[Category("Appearance")]
[DefaultValue("")]
[Localizable(true)]

this._DatePicker.Text = value;

Questo viene regsitrato nella pagina in questo modo:
<%@ Register Assembly="UserControl20, Version=0.0.0.0, Culture=neutral, PublicKeyToken=f93b385e790b3228" Namespace="UserControl20" TagPrefix="UC" %>
e viene utilizzato così:
<UC:DatePicker ID="txt_data" CssClass="textboxData" runat="server"
ImageCalendar="../image/calendar.gif" />
Su register da questo errore:

Version Information: Microsoft .NET Framework Version:2.0.50727.4952; ASP.NET Version:2.0.50727.4927
Ho provato a compilare la dll mettendo nell'assemblyinfo questo:
[assembly:System.Security.AllowPartiallyTrustedCallers]
ma niente.
Ho provato a compilare la dll firmando l'assembly ma niente.
Ho provato a compilare il sito Markando l'assembly con AllowPartiallyTrustedCallers impostato su Signig nella pagina delle proprietà del Deployement Project.
Io non so più cosa fare...quelli di register mi continuano a rimandare a questa guida:
http://msdn.microsoft.com/it-us/library/ms998341.aspx#paght000020_developing
ma oltre a impostazioni sul web.config che io non posso fare non vedo altro...
