Redeploying historical builds through TFS - tfs

Does TFS offer a way to save, track, and later redeploy builds by build number, or can you only deploy .dlls compiled from the current codebase? I'm looking for functionality similar to what you find in Changeman DS.

Yes. Every build definition in Team Build has a "retention policy" that defines how many historical builds should be kept, depending on certain criteria. You can also mark individual builds as "keep indefinitely." Kind of like a Tivo...
Example walkthru with screenshots: http://blogs.msdn.com/buckh/archive/2007/08/14/tfs-2008-a-basic-guide-to-team-build-2008.aspx
If you need to recover a build that has already been deleted from the drop share, you can do that too -- you'll just have to rebuild it. Simply queue up the build definition, but before you hit Go, type /p:GetVersion="XXX" in the text area at the bottom labeled "additional MSBuild arguments." XXX can be any versionspec, just like you'd use at the tf.exe command line. Examples might be "C12345" or "D1/10/2010" or "LsomeLabel".

How does TFS choose which check-ins to associate with a build?

Our builds generally have a mish mash of work items and commits associated with them and I cannot tell how TFS determines what to add. We are using TFS 2015 update 3 and TFVC.
When a build runs, it gets code from a location somewhere in the branching and folder of TFVC. Typically, something like "root\dev\src\component name" in this way we avoid getting all of the code in our repository and we have CI set up to run so that any changes in this folder will result in a CI build running.
We also run daily builds which run more tests and create a release package that is used by TFS Release Management. I would expect that any changes to code inside of the folder defined in setting up the repository for this build to be included in the associated change-sets of a build. I also expect that any changes checked-in outside of these branches would not be associated. But this is not the case. We see commits from across the entire project.
Does anyone know how this is supposed to work?
I am not sure if this should go in the question or the answer but I have found some additional information, thanks to the hints provided in the answers below.
It appears that the source settings will take the common root between mapped folders of the repository settings, so if I have 2 folders $/Relo/Dev/B1/src/Claims.Services and $/Relo/Dev/B1/src/PSScripts it will take the common root $/Relo/Dev/B1/src as the source settings and include any changes from that folder down within the build. Can anyone confirm this? Of course thats not what I want to have happen. In the History tab of the build definition if I looked at the diff I can see a field "defaultBranch" in the json which seems to be the value that controls this, is there any way to update this field directly?
TFS determines what changesets should be mapped to a build based on the Source Repository Mappings (Build vNext) in the build definition and the last successful build.
So, you will see a list of the changesets with files committed in the lowest common base of any of the mapped folders including all their descendents, since the latest successful build. Whenever you get a successful build (I hope that it happens more often than failing ones ;-)) the list will shorten and only show the last check-in.
Example mappings below will result in any changeset made to anything below $/Relo/Dev/B1/src (because it is the lowest common base):
$/Relo/Dev/B1/src/Claims.Services
$/Relo/Dev/B1/src/PSScripts
Similar it will pick up all the related work items to the above changesets.
This is what should happen. If you see something else, I would have a closer look at the Repository Mappings or Source Settings of the build definition.
#Noel - I guess you are using vNext build and not XAML builds. Or are you using a mix of XAML and vNext?
In general a scheduled TFS build will associate all changes which were not associated in the last successful run of the same build.
I suggest you check once again if the source folder locations are the same for CI build and Daily build?

TFS2012 Project Build Priority

Is there a way in TFS 2012 to set Project (not .csproj projects but TFS projects) build priority?
Currently we have many projects in TFS, one of which is a core project that many other projects reference. If someone checks in changes to both core and another project at once, the core project build doesn't always kick off first (I think they build in alphabetical order). It would be nice to be able to set the core project as the highest priority so that its build always runs first when changes to multiple projects are checked in. Is this possible?
There is no way to set the default build priority for a Build Definition. Since a Build Definition isn't bound to a Team project, but to a collection, there is also no way to configure the Queue to pick up builds from one Team Project before any others.
What you can do is to set a tag on an agent and then assign that tag to the build you want to take precedence. This will exclusively reserve the Build Agent to that specific build definition, causing it to jump in the queue.
Is there a way in TFS 2012 to set Project (not .csproj projects but TFS projects) build priority?
A project in TFS is quite a loose term which does not correspond to a VS project, it's actually used to refer to a product which can contain many branches. The high level project management tools then operate on the TFS "project".
If someone checks in changes to both core and another project at once, the core project build doesn't always kick off first (I think they build in alphabetical order).
Nope, assuming you don't have a custom build then they (the VS projects) don't build in alphabetic order at all, they build in order of dependency. Solutions are built in the order they are returned from the evaluation of the $(SolutionsToBuild) property (this does a wildcard search of the filesystem for .sln files, so maybe that's where your alphabetic observation comes from). Note that dependencies are evaluated on projects within a solution, there is no evaluation of dependencies across solutions.
For the following statements I'm going to assume that you have standard CI style builds gated upon checkin.
If a developer checks in everything at once then the checkin will happen as an atomic unit of work and the build will commence once the checkin is successfully committed. If this is not your experience then I would suggest that you either have funky stuff happening in a custom build, or the developer is checking blocks of work in separately rather than all at once.
Note that this happens per checkin per workspace - if two different developers check stuff in at the same time then whoever checks-in first will trigger the build, and the submission of the second developer will miss the build.

How to perform the Build in TFS2010? What is the Logic should we adopt and How to get a files from TFS 2010?

Currently we are using StarTeam to perform the build as well as versioning. we planned to migrate startteam to TFS2010. We have some script for perform the build. i wanted to change this script according to my requirement. i gone through the TFS but i had lot more confusion.
in StarTeam, we will get a files from "Ready to Build" label and perform the build. In TFS, how we are going to get a files from TFS? What concept should i use to get a files and perform the build? i have gone through the lot of commands like get, check-in, checkout etc..
If we use "tf get" command, we can get all the files from TFS but i have a clarification on that. shall i get all the files from TFS for every build? i hope, this is unnecessary headache.. correct me if i am wrong..
how we perform the build in TFS? i have read some types of build such as manual, gatedcheckin, Continuous Integration and schedule.
Is there any relationship between branch and build activities?
In TFS, What is the meaning of Workspace?
As said, many questions in one. Hope this helps along the way:
A workspace is a mapping between the server and a local storage,
similar to checkout in Subversion, view in ClearCase, etc.
"TF get" normally only fetches those files that have changed since
last update. You can force it to fetch everything - and sometimes
have to - but its not normally done.
Team Build is the recommended system to build with when using TFS. It can take some time to get into (Windows Workflow-based), but is quite powerful. There are default process definitions that set up the most common actions for you.
By default, you can't control whether to build by setting a certain label, but you can define that only this label should be used when builds are triggered. Labels in TFS work a little differently compared to other VCS, though, so maybe there's an 'opportunity' to re-think your build process along the way. If you're set on using a label as before, you'll need to build a Custom build activity.

Rebuilding historical builds through TFS with version numbers

I have automatic build numbering setup, based on build date/name, using approach proposed by John Robbins from Wintellect described here. So the version/resource file is automatically created on build time but not checked-in.
I wonder how to approach a problem of rebuilding historical versions (based on labels) and having the original build number/name in them. Is it possible to detect 'GetVersion' parameter of MSBuild and try to recreate the original build name from it?
Is it a sane approach anyway? What alternatives do you see?
It's not easy to build a specific changeset (though possible, if you pass the changeset number into your build script and modify the "Get Latest" portion of the build).
However, one easier way of handling this is to create a branch of your code. You can branch at a specific date or changeset, which will create a copy of code from that point in time. Your build scripts can then be pointed at this code.
With respect to your versioning problem: you may find that the only sensible way to do this is to hardcode the required version number. My understanding of your version numbering strategy is that it doesn't relate to anything you can derive from the source (such as the changeset number, date, or file content), and it isn't checked in - so re-calculating it will be pretty complicated!
You ask question Rebuilding historical builds but it actually Rebuilding historical change Set or label, I know what you mean but I am trying to tell you what I need to say, so I don't see that we need to build a label with the specific name the label or change set can has many build as needed and since we use the date and time in the build number it will more realistic to has the current time and date the build was taken instead of old one

TFS Build Architecture

I am preparing to move my team's source control from VSS over to TFS 2008.
This is for an asp.net website, and I am currently using a combination of nant scripts and Cruise Control to do all of the builds and deployments.
I've been trying to wrap my head around the best way to architect TFS build to do the same thing I'm doing with NANT and Cruise Control, but I can't determine the best approach.
Here are my requirements:
When code reaches a certain point, I manually apply a label to it.
This labeled code needs to be built and deployed to any of our 25 different Dev, QA, or production environments.
Any of these 25 environments can be on any current or past labeled version of the application.
I need to be able to deploy any labeled version of the application to any of the environments.
I'm currently accomplishing the above using NANT to perform the build, and using Cruise Control to just pass in command line options for which environment(s) to build and deploy. I have a Nant config file with a list of all of my environments, and an associated label each environment should currently be using. This file gets manually updated whenever a new label is created.
I know the approach I'm using for NANT probably won't be the same as with Team Build, but has anyone done something similar with Team Build and could share how you accomplished it?
Labeling in TFS is much more robust than in VSS. When you create a label, you can create based on a changeset, date, workspace version, heck even a different label. (BTW, I was grabbing a link and came across this post that you might find relevant.)
By default, a Team Build will build from the latest version of code in source, but you can override the "CoreGet" target in a build to build a specific version. Aaron Hallberg (a.k.a. TFS's John Skeet) shows an example here.
see 4.
I haven't personally had this difficult of a requirement, but I've done something similar. When you queue the build, you can pass in any number of parameters in a couple important ways, 1) through the response file and 2) at queue time (simple example here). In either case, two parameters could be which environment and which label/version number. At my current project, I have continuous integration turned on, so when code in a workspace is checked in, the current code is automatically labeled, pull the specifics for my drop location from the response file, then deploy to the respective location.
Given the fact that you have ~25 environments and n number of versions/labels, you could build a simple GUI that reads the current labels through the TFS API and lets you pick which version to build to a particular environment.
To answer the question, the way I addressed this was to use a combination of a custom build task, cruise control, and msbuild.
The custom build task allowed me to get the latest version from a specific branch and label.
Cruise control allowed me to pass in specific information for a specific build to MSbuild, using a config file, but initiate the build from a UI.
msbuild was used like normal, however it was called from cruise control, and the custom build task did most of the work.
