Free Series of SharePoint Workflow How-to Videos

This is the series of "How to" Document Workflow with SharePoint using Visual Studio 2008 (using the .NET Framework 3.0 for backward compatibility to Visual Studio 2005). I have created video's that show the most common requests that I have seen around MOSS/SharePoint 2007 workflow & document workflow.

VS2010 Professional .NET 4.0 Remote Debugging ASP Website Project


Trying to remote debug ASP website from VS2010 Pro to Windows Server 2003 machine.  Specifically, trying to debug a Web Service, but breakpoint says, "The breakpoint will not currently be hit. No symbols have been loaded for this document."  This happens for all compiled code though.  I have read this is due to missing PDB files and the work around is to manually copy them, as noted here.  Problem is, I cannot find any PDB files for my project, except referenced libraries, which I can remote debug.


  • web.config has <compilation debug="true">
  • Debugger is attached to wewp.exe process on remote server
  • Installed VS2010 remote debugger from DVD (as I can remote debug referenced libraries)

This is beyond frustrating.  I migrated my code from VS2008 .Net3.5 to VS2010 .Net4.0 to take advantage of the inherent multithreading framework.  Debugging works when using local host and was stable until deployment to test server.

Thanks in advance,


HttpHandler works with Visual Studio Development Server debugging, but not otherwise


Hi all,

I'm new to HttpHandlers.  I am writing an HttpHandler that reads uploaded files directly from the request stream to provide progress that can be queried using an AJAX request.  For large files, this seems to be faster than having ASP.NET load the file contents into Request.Files and then streaming the file from there to wherever it goes (Linq to SQL into a VARBINARY column in an SQL Server database.)

My HttpHandler works perfectly when I'm debugging using the Visual Studio Development Server, but doesn't work otherwise.  The application pool for this application in IIS 7 is set to run in Classic Mode, and the Handler Mappings screen in IIS says that I must manage managed handlers in system.web/httpHandlers. 

I set up in my applications Web.config file.

<add verb="GET,POST" path="*.upload" type="Namespace.For.UploadHandler, AssemblyForUploadHandler"/>

It works great, so long as I don't debug with the "Use Local IIS Web server" option.

What else do I need to do to get this to work?


Debugging ASHX after deployment



I'm finished with a part of my ASHX handler and need to test it against the software that'll be calling it using HTTP POST. The software required an https url so I created an internally hosted site in IIS and published the project there. 

Question now is how do I do any debugging on the script to see what data is coming out of it before the data goes back into the software that's calling it? Do I set something on the project itself to be able to step into the published DLL? 

Workflow Services: Visual Design of Workflows with WCF and WF 4


The .NET Framework 4 makes it easier than ever to implement WCF services using WF. We'll demonstrate just how easy it is by modeling a long-running, durable and instrumented workflow based on a real-world business case without having to write any code.

Foundations: Workflow Services for Local Communication


This month's column describes how to use WCF for communication between a workflow and a host application in Windows Workflow Foundation 3. This knowledge should help developers with their efforts using WF3 and prepare them for WF4, where WCF is the only abstraction over queues (referred to as "bookmarks" in WF4) that ships with the framework.

Parallel Debugging: Debugging Task-Based Parallel Applications in Visual Studio 2010


In Visual C++ 10 and the Microsoft .NET Framework 4, Microsoft is introducing new libraries and runtimes to significantly ease the process of expressing parallelism in your code base, together with new tool support for performance analysis and debugging of parallel applications. In this article, you will learn about debugging support in Visual Studio 2010, much of which is focused on task-based programming models.

Foundations: Windows Workflow Design Patterns


Design patterns provide a common, repeatable approach to solving software development tasks, and many different patterns can describe how to accomplish a certain goal in code. When developers begin working with Windows Workflow Foundation (WF), they often ask about how to accomplish common tasks with the technology. This month's column discusses several design patterns used in WF.
