The "BuildShadowTask" task failed
When Running tests Team System you got this error -
------------------------------------------------------------------------------------------------------
Error 8 The "BuildShadowTask" task failed unexpectedly.
System.NullReferenceException: Object reference not set to an instance of an object.
at Microsoft.VisualStudio.TestTools.BuildShadowReferences.BuildShadowTask.Execute()
at Microsoft.Build.BuildEngine.TaskEngine.ExecuteInstantiatedTask(EngineProxy engineProxy, ItemBucket bucket, TaskExecutionMode howToExecuteTask, ITask task, Boolean& taskResult) APITestProject
------------------------------------------------------------------------------------------------------
I got help from this MSDN Post
The BuildShadowTask is a component used by the Microsoft.TeamTest.targets used to build the private accessor DLL,
that a unit test uses to get at private and protected members of a test target.
It in turn calls the Publicize.exe executable to do the actual work.
To test “Internal” , “Private” or “Friend” methods you need to add Accessor to your TestProject.
Than Team System will add Accessor file with the name of the project you are testing.
Remove this file from the Test References folder and your tests will start working.
Good Luck
How To Add File Upload To Team System Web Test
May times people asks me how can I Upload File with Web Test, The first thing is to record the Web Test using “Web Test Recorder” or Fiddler.
But when running the Web Test its fails in the Upload section.
Why?
Before understanding the problem let get familiar with “File Upload Parameter” 
Right click on the required request and select “Add File Upload Parameter”
Then you can add the field name and the file location.
So why file upload fails?
Have a look at a short web test I record inside blogs.microsoft.co.il blogs, I upload a photo and only the file name is there.
When running the web test team system cannot file your file.
Add the full path of the file.
And Now your web test will work just fine.
Running Unit Tests End With - “The specified module could not be found”
“The specified module could not be found. (Exception from HRESULT: 0x8007007E)”
Some times your test relay on additional file that need to be in the same folder where Team System running the Test.
Those files can’t be add into the GAC and you can’t copy them manually each time.
So What Do Do?
We need to use Deployment settings
Deployment settings specify deployment location and any file to be deploy in the addition to the target assemblies
Open Test Configuration – Right click on Test Menu –> “Edit Test Run Configuration” –> “Local Test Configuration”
Select “Deployment” and check “Enable deployment”.
Add Folder/File to be deploy with your test.
Take Notice - If the deployment item are big (size) this will effect the run speed.
TFS Check-in Validation Tool
There is a new version available in CodePlex
Project Description
The TFS Check-in Validation Tool extends TFS Team Build 2008 by enabling buddy build queuing (pre-checkin), validating checkins using shelvesets, and build agent pooling, all from the VS 2008 IDE.

TFS API Part 18: More Basic Stuff On Workspaces
In my last post I showed how to TFS API Part 17: Get WorkSpaces Information
In this post I’ll show to go couple of basic actions on you workspace.
Demo Project
First add reference for
Microsoft.TeamFoundation
Microsoft.TeamFoundation.Client
Microsoft.TeamFoundation.Common.dll
Microsoft.TeamFoundation.VersionControl.Client.dll
located in - C:\Program Files\Microsoft Visual Studio 9.0\Common7\IDE\PrivateAssemblies\
Step 1 – Connect TFS + Create VersionControlServer Object
First I create a Domain Project Picker to get Team Foundation Server instance, and after getting tfs instance create new object type VersionControlServer.
DomainProjectPicker dp = new DomainProjectPicker(DomainProjectPickerMode.None);
dp.ShowDialog();
if (dp.SelectedServer != null)
{
tfs = dp.SelectedServer;
sourceControl = (VersionControlServer)tfs.GetService(typeof(VersionControlServer));
AddWorkSapces();
}
Step 2 – Get all workspace from local machine.
private void AddWorkSapces()
{
Workspace[] wss = GetWorkspaces();
foreach (Workspace ws in wss)
{
WorkSpaceItem item = new WorkSpaceItem(ws.Name, ws);
comboBox1.Items.Add(item);
}
}
* Create WorkSpaceItem
public class WorkSpaceItem
{
public string Name { get; set; }
public Workspace WorkSpace { get; set; }
public WorkSpaceItem(string name, Workspace workspace)
{
this.Name = name;
this.WorkSpace = workspace;
}
public override string ToString()
{
return this.Name;
}
}
public Workspace[] GetWorkspaces()
{
try
{
return sourceControl.QueryWorkspaces(null, sourceControl.AuthenticatedUser, System.Net.Dns.GetHostName().ToString());
//You also can get remote workspaces
//QueryWorkspaces(worspaceName,worksapceOwner,computer)
}
catch
{
throw;
}
}
Step 3 – Create Workspace
It’s a very simple action using tfs api, and can set folder and more workspace settings. (see comment)
private void btn_create_Click(object sender, RoutedEventArgs e)
{
sourceControl.CreateWorkspace(txt_name.Text);
//sourceControl.CreateWorkspace(txt_name.Text, Environment.UserName);
//sourceControl.CreateWorkspace(txt_name.Text, Environment.UserName, "Just Comment");
//sourceControl.CreateWorkspace(txt_name.Text, Environment.UserName, "Just Comment", new WorkingFolder(serveritem,localitem));
//sourceControl.CreateWorkspace(txt_name.Text, Environment.UserName, "Just Comment", new WorkingFolder(serveritem, localitem), "Computer Name");
//sourceControl.CreateWorkspace(txt_name.Text, Environment.UserName, "Just Comment", new WorkingFolder(serveritem, localitem), "Computer Name",FixMappingErrors);
}
Step 4 – Delete Workspace
private void btn_delete_Click(object sender, RoutedEventArgs e)
{
if (cob_workspace_list.SelectedItem != null)
{
WorkSpaceItem item = (WorkSpaceItem)cob_workspace_list.SelectedItem;
item.WorkSpace.Delete();
AddWorkSapces();
}
}
Step 5 – Get Pending Changes
private void btn_GetPendingChanges_Click(object sender, RoutedEventArgs e)
{
if (cob_workspace_list.SelectedItem != null)
{
WorkSpaceItem item = (WorkSpaceItem)cob_workspace_list.SelectedItem;
PendingChange[] changes = item.WorkSpace.GetPendingChanges(); ;
StringBuilder str = new StringBuilder();
foreach (PendingChange change in changes)
{
str.AppendLine(string.Format("File name:{0},Change type:{1}",change.FileName,change.ChangeType.ToString()));
}
MessageBox.Show(str.ToString());
}
}

Unhook The Link Between Microsoft Project and TFS
Some times you need to bind the project file with another TFS or if you made some mapping changes and need to rebind this connection.
There is no easy way to unhook the the binding between Ms Project and TFS:
- Close Microsoft Project
- Right click on the mpp file and choose Properties.
- Choose the Custom tab in the Properties window.
- Choose any Property listed there named "VS Team System Data Do Not Edit" and click Remove.
- Click Apply or Ok.
- Open the mpp file, and you will get a message saying its not associated with any TFS server. Click Ok and Save it.
- You will not get the error message every time you open the mpp file as long as you save it once after the message is received.
If you are using Ms Project Server you need to perform those steps before:
- Close MS Project.
- Disable the TFS addin by going to HKLM\Software\Microsoft\Office\MS Project\Addins\TfcOfficeShim.Connect
and change the ‘LoadBehavior’ from ‘3’ to ‘0’. - Open your project from Project server
- Go to step 3 in the instruction above.

This is Why Load Testing Is Important Not Just Before Release
After a short conversation with one of my customers he told me that a month ago he invited a “Load Expert” to perform load testing just before the company release the product.
After the “Load Expert” exam the system he said every thing will be all right, 30 people is nothing I’m 99% sure nothing will happen.
the customer asked him to perform the load test any way just to be sure… and the test passed just fine!
Then I got a call from the customer and he asked me to perform a load testing on their system.
Hey told me that he wants a second opinion, I exam the system and I found the major scenarios want to test.
After running the Load Test (Using Team System Team Edition – Obvious) we saw that even 30 users on their system cause very very very bad behavior.
Diving into the little details, me and the developers found couple of major problems (Security,Performance and more)
The story ends with – 2 month delay of the release.
