Code Name Indigo: A Guide to Developing and Running Connected Systems with Indigo

Posted By:      Posted Date: August 21, 2010    Points: 0   Category :ASP.Net

This article describes a collection of new programming frameworks that are part of "Longhorn," the upcoming version of Windows. "Indigo," the code name for this framework, provides rich support for service-oriented design that is complementary to traditional object-oriented approaches. Indigo marries the best features of .NET Remoting, ASMX, and .NET Enterprise Services into a unified programming and administration model. Indigo's deep support for standard protocols, including HTTP, XML, and SOAP, makes it easier to integrate applications and services without sacrificing security or reliability.

High Availability: Keep Your Code Running with the Reliability Features of the .NET Framework


Reliability requires the capacity to execute a sequence of operations in a deterministic way, even under exceptional conditions. This allows you to ensure that resources are not leaked and that you can maintain state consistency without relying on application domain unloading (or worse, process restarts) to fix any corrupted state. Unfortunately, in the.NET Framework, not all exceptions are deterministic and synchronous, which makes it difficult to write code that is always deterministic in its ability to execute a predetermined sequence of operations. In this article Stephen Toub will show you why, and explore features of the .NET Framework 2.0 that help you to mitigate these situations and write more reliable code.

.NET Internals: Examine Running Processes Using Both Managed and Unmanaged Code


There are plenty of times when you need to get information on running processes, not the least of which is during performance tuning. Using the techniques in this article and special .NET classes you'll see how to get a process' ID, name, priority, number of threads, kernel handle, and memory consumption, as well as its user-mode, kernel-mode, and total elapsed running time and put them to use in a custom app called AssemblyBrowser.

Virtual Source Code Control Systems: Promoting and Managing Projects using Visual SourceSafe


Source code control systems like Microsoft Visual SourceSafe can simplify just about any development project, and make it easier for your code to move safely among individual programmers, development teams, and project stages. Visual SourceSafe provides an object model that you can use as the basis of your own customized source code control environment. To give you an idea of what is possible, we'll walk you through the elements of a browser-based source code control system built with Visual SourceSafe, ASP, and VBScript. This simple system lets members of your team build, label, and promote individual files or entire projects, and to reverse promotions.

Is your code running in a SharePoint Sandbox?


You could execute a function call that is not allowed in the sandbox (for example call a static method on SPSecurity) and catch the exception. A better approach is to test the friendly name of you app domain:

AppDomain.CurrentDomain.FriendlyName returns "Sandboxed Code Execution Partially Trusted Asp.net AppDomain"

Because you can never be sure that this string changes in the future, a safer approach will be:

Detect if code is running inside SQL Server.

Can managed code "detect" if it is running in the normal .Net CLR or the special SQL Server CLR? Is there some environment flag or field we can look at at runtime? Thanks Cap'n  

I am using the following code to check to see if a panel is visible or not before running javascript

Using VB, VS 2010, when I run the following code, I get an error because it executes the code even if I have Panel7 set to invisible.  I am trying to use javascript to see if the panel is visible or not before executing the code.var panelRef7 = document.getElementById('<%= Panel7.ClientID %>'); if (panelRef7) { $find('DragP7').add move(savePanelPosition); }  What am I doing wrong?   Thanks

Running code after site definition site creation in a event receiver or feature receiver

Hi guys I've got a site definition which is pretty much based on STS.This is it's own sharepoint project. Let's call this project SiteDefProj. Next in another SharePoint project (same solution though). Let's call this CustomListProject. In this project I've got a feature which provisions a bunch of lists based on custom content types - this feature is a site scoped. Let's call this feature: CustomListInstances. I have added a feature receiver to this feature to execute some custom code on the lists themselves (under feature activated) In my ONET.XML (part of the SiteDefProj) I have CustomListInstances feature ID as part of my <sitefeatures>. When I do a create site I can actually step through the code and see it actually being executed but after the site is created the list instances are created but it's like the code never run or did anything. The weird part is that stepping through the code while creating a site collection using my SiteDefProj the code runs great with no errors. All lists are there and the code runs smooth. If I manually create a STS site and activate my feature everything works and the code does actually run and the effects are visible after the feature is created. Again I can actually step through it in debug. My suspicion is that there's some sort of a race condition in the CREATE SITE functionality where maybe the web or site collection hol

can I tell programmatically whether the code is running in sandbox?


The title says it all really! I want to be able to check in my code whether the current environment is live or sandbox - is it possible?



Running a feature activated code during new site provisioning.

I would like to be able to run some simple code that have in a feature whenever a new site is provisioned.  I created the feature and it works just like I want it to.  I left it activated and saved the site template.  Now when I create a new site based on the saved site template the feature activated code no longer runs unless I deactivate and then activate.  I know this isn't suppose to work this way, and after much searching on the internet I am finding the feature stapling (not what I want, that seems to be what I have already done) and SPWebProvisionProvider.  The provider might be what I want but I am not sure how it works and there are no good examples on how to get one created in code and where to place it so that a user can utilize it when creating a new site.  Can someone explain this concept to me in ad nauseum detail.  Thanks in advance.

Can't access static member in code, but while running "QuickWatch" sees it. What the?


HI everyone,

I'm working with two Visual Studio 2005 solutions.

The first is "WinX" with a project called "WinX". There's a class in the WinX project in a namespace called "WinX" with a class "frmMain". frmMain is the main form for the application, and is always open.

We have this static member declared as so in frmMain:

public static bool IsfrmViewTaskFormOpen = false;

Enter our second solution "TasksProcessScreen" with a project "TasksProcessScreen" which has a namespace of "TasksProcessScreen" with a public class frmViewTask. The solution has the "WinX" project added as a project.

In frmViewTask, there is the following code:

private void frmViewTask_FormClosed(object sender, FormClosedEventArgs e)


   //This does NOT compile! It says "WinX" does not exists in the current context.

   if (WinX.frmMain.IsfrmViewTaskFormOpen)
