TFS2010 Team build - how to deploy databases before running unit tests - database-deployment

Question

I followed How to prepare database for TFS deployment walkthrough
and my build script successfully deploys the database at the end of the build process. However, I need the database to be deployed before running unit tests.
I tried copying the step and pasting it right above "Get Impacted Tests, Index Sources and Publish Symbols". However, the build process returns the following error:
* The deployment manifest file Database_Core.deploymanifest does not exist
Here is the excerpt from my xaml file for the database deploy:
<Sequence DisplayName="Deploy Database" sap:VirtualizedContainerService.HintSize="486,330">

This is exactly what I needed as well. Please see here a PNG that depicts all points that follow:
At first I arranged a set of Arguments in my build process template, where I set the target Database host, the user & the password. (See "Argument" section)
In case the current Project's Unit tests need a running DB, I set in "Items to build" 2 different projects:
In the first slot the *.dbproj
In the second the SLN itself
Now within the Build process template I 've expanded the "Run MSBuild for project" as a Sequence (See "Sequence"), ensuring that that the MSBuild Arguments are different in the left case :
Arguments for MSBuild on the left side ("Run MSBuild + Deploy DB"):
String.Format("/p:SkipInvalidConfigurations=true /t:Build;Deploy /p:TargetConnectionString=""Data Source={0}%3Buser={1}%3Bpwd={2}"" /p:DeployToDatabase=true /p:TargetDatabase={3}_{4} {5}",
TargetMachineToDeployDB, DBUsername, DBPassword, DBName, BuildDetail.BuildNumber.Replace(".", "_"), MSBuildArguments)
In case it's not too obvious, the connection between the Arguments & the displayed params in the Definition are:
- TargetMachineToDeployDB = "PC name where Database shall be deployed"
- DBUsername = "Database Username"
- DBPassword = "Database Password"
- DBName = "Database Prefix Name" (I concat the current buildname)
Arguments for MSBuild on the right side ("Run MSBuid for SLN/Project"):
String.Format("/p:SkipInvalidConfigurations=true {0}", MSBuildArguments)
Note that if I deployed a DB on the left side, I will also set a DBHasBeenSet into TRUE, which will also trigger some file handling inside "Adaptations in Source Files". These include redirecting our NUnit DLLs to the newly constructed DB. I can set more details on that, if you 'd like.

You can change where this happens in your deployment.
I would deploy the database right after your main build command in the workflow. In 2008 with the .proj this a little more clear because you would simply add it to <Target Name=BeforeTest> Try moving it to an earlier point in the process.
