TFS 2010 - Lab Build Definition appends the configuration to build output path $(BuildLocation)

Consider you have two build definitions:

• DailyBuild - Uses DefaultTemplate.xaml
• CIBuild - Uses LabDefaultTemplate.xaml

If you do not specify any configurations explicitly in DailyBuild, the CIBuild would work fine and you will be able to run the Build-Deploy-Test workflow smoothly.

However, as soon as you explicitly specify a configuration in DailyBuild, the CIBuild would start failing because it wont be able to find the binaries in the build drop.
This is because it appends the configuration to build output path in $(BuildLocation)

The solution is to modify the LabDefaultTemplate.xaml
Before:
<If Condition="[LabWorkflowParameters.BuildDetails.IsTeamSystemBuild = True]" DisplayName="Compute build location needed" sap:VirtualizedContainerService.HintSize="858,201">

       <If.Then>

         <Assign DisplayName="Compute build path" sap:VirtualizedContainerService.HintSize="291,100">

           <Assign.To>

             <OutArgument x:TypeArguments="x:String">[BuildLocation]</OutArgument>

           </Assign.To>

           <Assign.Value>

             <InArgument x:TypeArguments="x:String">[If(LabWorkflowParameters.BuildDetails.Configuration Is Nothing, BuildLocation, If(LabWorkflowParameters.BuildDetails.Configuration.IsEmpty Or (SelectedBuildDetail.Information.GetNodesByType(Microsoft.TeamFoundation.Build.Common.InformationTypes.ConfigurationSummary, True)).Count = 1, BuildLocation, If(LabWorkflowParameters.BuildDetails.Configuration.IsPlatformEmptyOrAnyCpu, BuildLocation + "\" + LabWorkflowParameters.BuildDetails.Configuration.Configuration, BuildLocation + "\" + LabWorkflowParameters.BuildDetails.Configuration.Platform + "\" + LabWorkflowParameters.BuildDetails.Configuration.Configuration)))]</InArgument>

           </Assign.Value>

         </Assign>

       </If.Then>

     </If>

 After:

 <If Condition="[LabWorkflowParameters.BuildDetails.IsTeamSystemBuild = True]" DisplayName="Compute build location needed" sap:VirtualizedContainerService.HintSize="858,201">

       <If.Then>

         <Assign DisplayName="Compute build path" sap:VirtualizedContainerService.HintSize="291,100">

           <Assign.To>

             <OutArgument x:TypeArguments="x:String">[BuildLocation]</OutArgument>

           </Assign.To>

           <Assign.Value>

             <InArgument x:TypeArguments="x:String">[BuildLocation]</InArgument>

           </Assign.Value>

         </Assign>

       </If.Then>

     </If>
