System.Security.SecurityException: Request for the permission of type 'System.Web.AspNetHostingPerm


Good Day all,

Having an issue with an outside user accessing my IIS7 box. I do not have this problem when running the website from my host machine. I found this post: Http://forums.asp.net/t/1371394.aspx. I assure you that this is not a solution because I am not storing any of my files on a network share. 

What do you think my approach should be. 

I already have read rights to IIS user to my BIN folder. 

Thanks for the help.

This is frustrating, and I don't know how to solve it.

I have a strange problem. I am adding a LinqDatasource object, and set the context:

        protected void LinqDataSource_ContextCreating(object sender, LinqDataSourceContextEventArgs e)
            e.ObjectInstance = new KaruselaDataContext(ConfigurationManager.ConnectionStrings["ConnectionString"].ConnectionString);

Then I get this error:
The type 'System.Data.Linq.DataContext' is defined in an assembly that is not referenced. You must add a reference to assembly 'System.Data.Linq, Version=, Culture=neutral, PublicKeyToken=b77a5c561934e089'.


On web.config I already have this:
<add assembly="System.Data.Linq, Version=, Culture=neutral, PublicKeyToken=b77a5c561934e089"/>

NOTE: The datacontext is in a different project (DLL proect) where I added a refernce to System.Data.Linq.

is there another way adding a refernce to a web project? or only though teh web.config?

Design Patterns: Simplify Distributed System Design Using the Command Pattern, MSMQ, and .NET


Service-oriented architecture is a great framework when you need to perform distributed computing tasks over the Internet. But when you want to perform processing inside your local network, a different solution may provide a better fit. That solution, based on the Command pattern, uses Windows services and Microsoft Message Queuing to implement a queued system that meets your needs better than a service-oriented solution. This article explains how to build it.

Types in Yukon: Managed UDTs Let You Extend the SQL Server Type System


The next version of SQL Server, code-named "Yukon," will offer enhanced support for user-defined types (UDTs). Because UDTs can be managed by the CLR, you can represent a wide variety of data structures to create types not possible with previous versions of SQL Server. With UDTs you can more precisely control the kind of data your type accepts, resulting in better data management. This article explores UDTs in "Yukon" and covers their design and implementation.

.NET Remoting: Design and Develop Seamless Distributed Applications for the Common Language Runtime


Prior to the advent of .NET, DCOM was the underlying technology for remote communications between Windows-based applications. But DCOM is quirky to set up and configure and not as interoperable as it should be. In .NET, XML Web Services and .NET Remoting are a seamless and effective answer to the demand for tools to build distributed applications.This article provides a primer on .NET Remoting with insights into the internal plumbing. Important aspects of remoting, such as channels, object lifetime management, and clients for remote objects are discussed. In addition, some practical examples are provided.

VS 2010 XAML Design View Load always fail with a Type Load Exception

Create a new WPF project in VS and change nothing. The Design View will fail to load with the error below. Error    1    Could not load type 'Microsoft.Expression.DesignModel.Core.ISharedInstanceBuilder' from assembly 'Microsoft.Expression.DesignModel, Version=, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a'. Microsoft.Expression.DesignModel is an assembly from Expression Blend. I ever installed Blend 4 RC and uninstall and install Blend 4. I Reflector the assembly I have under Blend 4 bin folder. And cannot find a interface named ISharedInstanceBuilder. But the WPF project is a Template project without any changes. How it get related with Blend 4? And how to fix it? Thanks.  

WPF get Type in Design time?

Well here is my problem i have a class that inherits UserControl (View) now i use this class instead of the UserControl and i need to get the type in some cases now this works great a run time .GetType() returns the right type (for example ShellView) but when running in design time (the wpf editor in Visual Stuido) .GetType() returns the base type instead of the type of the current xaml document... Example: public class View : UserControl { public override void OnApplyTemplate() { MessageBox.Show(this.GetType().ToString()); base.OnApplyTemplate(); } } My XAML: <local:View x:Class="WpfApplication2.Test" xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006" xmlns:d="http://schemas.microsoft.com/expression/blend/2008" xmlns:local="clr-namespace:WpfApplication2" mc:Ignorable="d" d:DesignHeight="300" d:DesignWidth="300"> <Grid> </Grid> </local:View> so in this case when i open Test in the designer i get a message saying View, but when i run the program i get a message box saying Test.. How can i get the right type in design time im totaly lost on this problem..

I received the following error...*****System.Data.SqlClient.SqlError: There is insufficient free space on disk volume 'C:\' to create the database.

(Microsoft.SqlServer.Smo)*****I have looked at the solution recommended on this forum http://www.sqlteam.com/forums/topic.asp?TOPIC_ID=79848 but I am still baffled as to why it says that I don't have enough disk space?  I ran the RESTORE FILELISTONLY command and it told me that the "size" was 1.4 GB and I've got 60GB left.

A first chance exception of type 'System.ArgumentException' occurred in System.Windows.Forms.dll

I've read a bit about this error and maybe I have nothing to worry about.  BUT ... my simple little app gets 7 of these before it even gets to the first Dim statement in the Class Form1!  I found and followed instructions on how to have the Debugger intercept these exceptions but it seems that they are not being intercepted.  I only know that they have happened because of the messages in the Immediate Window.  In the Designer all I have is 5 Labels and 5 TextBoxes.   Any thoughts on how I could get to the cause of these messages? Thanks,  Bob
