tfs 2010 RC Agile Process template update New Task progress report

Clarity Blogs: ASP.NET — Fri, 12 Mar 2010 00:00:00 GMT

Maybe my next post will just be about why I am so excited and impressed with the out of the box templates. But, for this first blog with my new focus, I thought I would just walk through the process I went through to create a task progress report (to enhance the out of the box Agile template).

So, I started with the MSF for Agile Development 5.0 RC template. After reviewing the template, I came away pretty excited about many of the new reports. I am especially excited about the reporting services reports. The big advantage I see here is that these are querying the Warehouse directly instead of the Analysis Services Cube which means that they are much closer to real-time which I find very important for reports like Burndown and task status. One report that I focused on right away was the User Story Progress Report. An overview is shown below:

This report is very useful, but a lot of our internal managers really prefer to manage at the task level and either dont have stories in TFS or would like to view this type of report for tasks in addition to the User Stories. So, what did I do?

Step 1: Download the Agile Template

In VS 2010 RC, open Process Template Manager from Team->Team Project Collection Settings. Download the MSF for Agile Development template to your local file system. A project template is a folder of xml files. There is a ProcessTemplate.xml in the root and then a bunch of directories for things like Work Item Definitions and Queries, Reports, Shared Documents and Source Control Settings.

Step 2: Copy the folder

My plan here is to make a new template with all of my modifications. You can also just enhance update the MSF template. However, I think it is cleaner when you start making modifications to make your own template. So, copy the folder and name it with your new template name.

Step 3: Change Template Name

Open ProcessTemplate.xml and change the <name> of the template.

Step 4: Copy the rdl of the Report you want to use a starting point

In my case, I copied Stories Progress.rdl and named the file Task Progress Breakdown.rdl. I reviewed the requirements for the new report with some of the users here and came up with this plan. Should show tasks and be expandable to show subtasks. Should add Assigned To and Estimated Finish Date as 2 extra columns.

Step 5: Walkthrough the existing report to understand how it works

The main thing that I do here is try to get the sql to run in SQL Management Studio. So, I can walkthrough the process of building up the data for the report.

After analyzing this particular report I found a couple of very useful things. One, this report is already built to display subtasks if I just flip the IncludeTasks flag to 1. So, if you are using Stories and have tasks assigned to each story. This might give you everything you want.

For my purposes, I did make that change to the Stories Progress report as I find it to be a more useful report to be able to see the tasks that comprise each story. But, I still wanted a task only version with the additional fields.

Step 6: Update the report definition

I tend to work on rdl in visual studio directly as xml. Especially when I am just altering an existing report, I find it easier than trying to deal with the BI Studio designer. For my report I made the following changes.

Updated Fields
- Removed Stack Rank and Replaced with Priority since we dont use Stack Rank
- Added FinishDate and AssignedTo
Changed the root deliverable SQL to pull @tasks instead of @deliverablecategory and added a join CurrentWorkItemView for FinishDate and Assigned to

SELECT cwi.[System_Id] AS ID FROM [CurrentWorkItemView] cwi
            WHERE cwi.[System_WorkItemType] IN (@Task)
            AND cwi.[ProjectNodeGUID] = @ProjectGuid SELECT lh.SourceWorkItemID AS ID FROM FactWorkItemLinkHistory lh
            INNER JOIN [CurrentWorkItemView] cwi ON lh.TargetWorkItemID = cwi.[System_Id]
            WHERE lh.WorkItemLinkTypeSK = @ParentWorkItemLinkTypeSK
                AND lh.RemovedDate = CONVERT(DATETIME, '9999', 126)
                AND lh.TeamProjectCollectionSK = @TeamProjectCollectionSK
                AND cwi.[System_WorkItemType] NOT IN (@DeliverableCategory)

Added AssignedTo and FinishDate columns to the @Rollups table
Added two columns to the table used for column headers

Added Cells for the two new headers
Added Cells to the data table to include the two new values (Assigned to & Finish Date)
Changed a bunch of widths that would change the format of the report to display landscape and have room for the two additional columns
Set the Value of the IncludeTasks Parameter to 1 <ReportParameter Name="IncludeTasks">
      <DataType>Integer</DataType>
      <DefaultValue>
        <Values>
          <Value>=1</Value>
        </Values>
      </DefaultValue>
      <Prompt>IncludeTasks</Prompt>
      <Hidden>true</Hidden>
    </ReportParameter>
Change a few descriptions on how the report should be used

This is the resulting report

I have attached the final rdl.

Step 7: Update ReportTasks.xml

Last step before the template is ready for use is to update the reportTasks.xml file in the reports folder. This file defines the reports that are available in the template.

Step 8: Upload the template

Open the process Template Manager just like Step 1. And upload the new template.

Thats it. One other note, if you want to add this report to existing team project you will have to go into reportmanager (the reporting services portal) and upload the rdl to that projects directory.

Jeremiah is probably my favoriate Silverlight Prodagy and he has done it again with this wonderful hack, 'Use Native/Desktop CLR Without COM Registration' I like the first line, "WARNING: Information and code here can easily be abused. Please do not use it as a crutch in application planning, but more for utter despair or experimentation. Thus I wrote this blog post from that perspective."Certainly Jeremiah's code can be abused but what is really interesting to me is...

Blog Rebranding

Clarity Blogs: ASP.NET — Fri, 12 Mar 2010 00:00:00 GMT

I have been spending more and more time on learning as much as I can on Agile Development and also have been fairly immersed in rolling out TFS 2010 in our environment. I feel like it is time to talk about some of my experiences. With that, I am rebranding my blog to focus on these topics. I am going to start with a bunch of blogs on the process I have gone through getting TFS 2010 configured for our development teams.

Last week, Brian Harry was in our office and gave a great talk on the improved tools in TFS 2010 and how Microsoft uses the tools internally. I followed that up with a high-level overview of the improved out of the box process templates and the process to customize them. I am definitely very excited about the new features in 2010 and hopefully will keep up my motivation to blog about it. I am writing my first post right now about the process I went through to build a task progress report based on the user story progress report in the MSF for Agile Development template. Stay tuned

Silverlight Reporting Application Part 3.5 - Prism Background and WCF RIA [Series Intermission]

the telerik blogs — Fri, 12 Mar 2010 00:00:00 GMT

Taking a step back before I dive into the details and full-on coding fun, I wanted to once again respond to a comment on my last post to clear up some things in regards to how I'm setting up my project and some of the choices I've made. Aka, thanks Ben. :)

Prism Project Setup

For starters, I'm not the ideal use case for a Prism application. In most cases where you've got a one-man team, Prism can be overkill as it is more intended for large teams who are geographically dispersed or in applications that have a larger scale than my Recruiting application in which you'll greatly benefit from modularity, delayed loading of xaps, etc. What Prism offers, though, is a manner for handling UI, commands, and events with the idea that, through a modular approach in which no parts really need to know about one another, I can update this application bit by bit as hiring needs change or requirements differ between offices without having to worry that changing something in the Jobs module will break something in, say, the Scheduling module.

All that being said, here's a look at how our project breakdown for Recruit (MVVM/Prism implementation) looks:

This could be a little misleading though, as each of those modules is actually another project in the overall Recruit solution. As far as what the projects actually are, that looks a bit like this:

Recruiting Solution
- Recruit (Shell up there) - Main Silverlight Application
- .Web - Default .Web application to host the Silverlight app
- Infrastructure - Silverlight Class Library Project
- Modules - Silverlight Class Library Projects

Infrastructure &Modules

The Infrastructure project is probably something you'll see to some degree in any composite application. In this application, it is going to contain custom commands (you'll see the joy of these in a post or two down the road), events, helper classes, and any custom classes I need to share between different modules. Think of this as a handy little crossroad between any parts of your application.

Modules on the other hand are the bread and butter of this application. Besides the shell, which holds the UI skeleton, and the infrastructure, which holds all those shared goodies, the modules are self-contained bundles of functionality to handle different concerns. In my scenario, I need a way to look up and edit Jobs, Applicants, and Schedule interviews, a Notification module to handle telling the user when different things are happening (i.e., loading from database), and a Menu to control interaction and moving between different views. All modules are going to follow the following pattern:

The module class will inherit from IModule and handle initialization and loading the correct view into the correct region, whereas the Views and ViewModels folders will contain paired Silverlight user controls and ViewModel class backings.

WCF RIA Services

Since we've got all the projects in a single solution, we did not have to go the route of creating a WCR RIA Services Class Library. Every module has it's WCF RIA link back to the main .Web project, so the single Linq-2-SQL (yes, I said Linq-2-SQL, but I'll soon be switching to OpenAccess due to the new visual designer) context I'm using there works nicely with the scope of my project. If I were going for completely separating this project out and doing different, dynamically loaded elements, I'd probably go for the separate class library. Hope that clears that up. In the future though, I will be using that in a project that I've got in the "when I've got enough time to work on this" pipeline, so we'll get into that eventually- and hopefully when WCF RIA is in full release!

Why Not use Silverlight Navigation/Business Template?

The short answer- I'm a creature of habit, and having used Silverlight for a few years now, I'm used to doing lots of things manually. :) Plus, starting with a blank slate of a project I'm able to set up things exactly as I want them to be. In this case, rather than the navigation frame we would see in one of the templates, the MainRegion/ContentControl is working as our main navigation window. In many cases I will use theSilverlight navigation template to start things off, however in this case I did not need those features so I opted out of using that.

Next time when I actually hit post #4, we're going to get into the modules and starting to get functionality into this application. Next week is also release week for the Q1 2010 release, so be sure to check out our annualWebinar Week (I might be biased, but Wednesday is my favorite out of the group).

DotNetNuke 5.3.0 Almost there

Joe Brinkman — Fri, 12 Mar 2010 00:00:00 GMT

The 5.3.0 development cycle has been unlike any in our 7+ year history. In some respects this is good and in others not so much. As I explained in my Just Like Clockwork post, we are working hard to make monthly releases a habit and to have release schedules that are predictable. DotNetNuke 5.3.0 marks the first major release we have attempted since splitting our engineering group into feature development and maintenance groups. As always, doing anything for the first time can be challenging. The...
