I am not sure if this is a defect, or expected behavior, but I find when I update a TaskGroup or a Library in TFS, these changes do not always cascade down to each consumer. The refresh to consumer does happen sometimes, but it's hit or miss at best.
If these Task Groups and Library features don't cascade down when you update them then what is the point?
How did you use the Task Group/Library (Variable Group)?
Based on my test on TFS 2017 Update 3 (Version 15.117.27414.0), the Task Group/Library (Variable Group) works as expected.
That means once you have updated the Task Group/Library (Variable Group), then the corresponding changes and values will also reflect to the build/release which using the specific Task Group/Library.
For example, once I updated the value of the variables (Library-variable group), then the value also changed in the next release. Reference below screenshot.
More information please refer to Variable groups for builds and releases.

I've tried to get this to work a few times but running into the same problem.
A number of workitems are failing with the following error:
OH-Connector-0143: Target system does not contain value : Resolved for field: State for entityType: Task
I've replaced the source projects WIT with the standard versions and I've tried to change the status on the work items referred to. All are Task type work items and have had state set to Resolved at some point although I have checked all failed items and none currently set to that state.
We are also seeing another failure message which I have assumed is caused by the above error which is:
OpsHub-012010: Processing blocked - earlier event(s) for entity 6960 have to be processed first.
Additionally, no source has migrated. It is my assumption that this is because of the work item failures?
The reason the failure is because the history of those workitems has already been persisted. It cannot be changed. You can update the current value of those WITs with an available state, but the historic revisions will remain the same.
OpsHub's Migration Tool migrates your entire history. Therefore, while processing the revisions where the State was 'Resolved', the issue is encountered.
And yes, the 'processing blocked' errors are because of the above error and the SCM migration will not start until the WIT is done due to linkage dependency.
We have our projects configured with MSBuild script customization to modify the ApplicationVersion property in the project and copy that into the AssemblyInfo.cs file when the project builds. The problem is that we have TFS set up to run on a nightly schedule, with "Build even if nothing has changed since the previous build" unchecked. But since TFS itself is producing this version update, it will rebuild and increment every night. So this is sort of an infinite loop of our own design, but trying to figure out how to get out of it.
If the "changed since the previous build" detection is based on the history timestamp, ideally it'd be nice if when the version gets updated and commits to TFS it does it with a timestamp that precedes the build time. Is that even possible?
If the "changed since the previous build" detection is based on some boolean/bit flag, is there a way to reset it?
Using TFS 2012.
I'm assuming that you're checking in the new version of the assemblyinfo.cs once it's been updated, and this is why TFS is queuing a new build. Have you tried adding a comment to the checkin of ***NO_CI*** This will definitely suppress a CI build but I'm not 100% certain if it will work in your scenario.
Another option is generating the version number via an algorithm rather then just incrementing a counter and checking it back in to Version Control. This circumvents the issue of a new build being triggered
i.e if your version number looks something like
1.2.3.4
Where 1 is Major (modified by a human not the build process)
2 is minor (also modified by a human)
the final 2 digits are then updated by an automated process.
You could use number of days since January 2000 for digit 3 (an arbitrary number but something that would change on a daily basis) and either the latest changeset number in Version Control or the total number of builds performed by TFS for digit 4.
This would fulfill 2 requirements, that version numbers are unique for a given build of an assembly, they always go up.
I would suggest that you don't check the new version number into TFS. There is no value in having the version number in there.
I typically set the checked in assembly info numbers to all zeros. ( 0.0.0.0) and never update them except locally for the build.
This gives you the benefit of always being able to identify locally built DLLs.
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.
We're using Team Foundation Service instead of a local TFS.
Our solution was created on Visual Studio 2012.
My problem is now that we want all assemblies to have the same version number (this part is already solved by using a CommonAssemblyInfo.cs that is linked into all projects).
The issue I'm facing right now is that we need the tfs changeset number at the last digit of the assembly version (e.g. 1.0.0.4711 where 4711 is the changeset number).
I've found several examples, but none of them worked for me.
And yes, I especially searched here on stackoverflow a lot.
I also have to admit that I've never looked into the MSBuild scripts...
Can anyone please give me a hint on how to accomplish this?
Is it for example possible to use the MSBuild Extension Pack on Team Foundation Service (not local TFS) and if, how to do that?
As always, time is my worst enemy...
Note that from 2010 Tfs employs Windows workflow for building the package the workflow calls msbuild for compiling the projects only - while its possible to pass changeset this way to msbuild its rather more hops.
Following deals with your problem, however the linked solution is more complex that needed:
Can assembly version been automatically updated with each TFS 2010 Build?
This is one of best series of tutorials on the custom build activities, the author is on stack as well i believe, one specificly about versioning
http://www.ewaldhofman.nl/post/2010/05/13/Customize-Team-Build-2010-e28093-Part-5-Increase-AssemblyVersion.aspx
In short you need a custom activity to run before compilation on source files, find all CommonAssemblyInfo.cs files, feed this list to your custom activity, it modifies the values inside with passed value of full version number or only the changeset and optionaly check in the change (probably not since your changeset will be out of sync then).
You can also take a look at https://tfsbuildextensions.codeplex.com/ set of activities there is TfsVersion activity among them, at the very least it will provide examples.
Functionality need for this should be available through Team Explorer and source control - The Custom activity assemblies and build templates usually are located in folder in your team project root - the location of this folder is defined for build controller you can change this through team explorer build section.
Changeset is available from value BuildDetail.SourceGetVersion, not sure if this was fixed/changed in 2012 however there were 2 issues about this value in 2010
Its doesnt respect GetVersion override in default build template - you will manualy need to update if override is used
When running latest build (no override) it will get the last changeset number from tfs - depending on your branches this may not be the same as 'last' changeset for the branch of build. You will either have to live with this, provide overrides for each build or implement activity that checks branch history for last changeset value and overrides it again.
It should be noted that GetVersion should be able to accept any sourcespec version - changeset, date, label etc. I havent played around with this enough to provide more details to you.
Colin Dembovsky wrote a great overview of doing version embedding using the new pre-build script setting in TFS 2013 build definitions.
The Changeset number is easily accessible within the pre-build process in the environment variable TF_BUILD_SOURCEGETVERSION. I was able to use this to embed the Changeset value in our binaries using a script based on Dembovsky's work above. (I used Perl, not powershell, so you probably don't want to see it ;-)
This approach doesn't require any changes to the build workflow which makes it a big win for me.
I've used Wintellect's solution - MSBuild-only, no TFS magic needed. I also added to the auto-generated CSharp file:
[assembly:AssemblyInformationalVersion("$(BuildNumber)")]
So I get the TFS build number.
We have begun using the following branching structure in TFS 2010:
All changes so far have been performed in the Development branch, and all check-ins have been associated with a Task work item. The Tasks are all children either of a Bug or a Product Backlog Item work item. Each CI build is triggered for a particular changeset, and the changeset is associated with a Task, so we can manually figure out which Bug or PBI was just built.
Some time after the code has been built, deployed to our Integration environment and tested by the developer, it is merged to the Main branch. Obviously, more than one changeset may be merged to Main at the same time. The nightly build will build this code if we don't manually trigger the nightly before that. QA will later deploy one of these "Main" builds to the QA environment.
There may have been several builds of the Main branch since the last time QA have deployed. These builds are associated with the "Merge" changesets, not with the original changesets which were associated with the Tasks.
How do I determine the set of tasks which have been addressed by a given "Main" build, which is a build of a different branch than the one associated with the Task work items?
Once we've begun preparing for a release, we may very well need to make changes in the Release branch, which will complicate things further since we will be merging back from Release to Main, and the Release changesets will be associated with Tasks. Those will then be merged to Development, making life even more interesting!
P.S. The question "How to determine the work items associated with a source branch in TFS 2010?" comes close to asking the same question, but not quite.
Take a look at Jacob Ehn's blog post Automatically Merging Work Items in TFS 2010. He wrote a plug in that can be downloaded from codeplex. It will automatically associate the work items that were associated with the merged changesets. So when you merge to Main or Release the work items will be associated with the changesets in those branches, and the work items will be included in the build reports for builds off of those branches. The plug-in is super easy to deploy.
The other option is that you can build a custom workflow activity that you can run during your build that can traverse the merge history for each of the changesets that would normally be associated. It's essentially walking the tree starting with a known set of associated changesets. I would prefer this approach since you can let your developers worry about only needing to associate work items with the original changesets instead of having to also do it with merge changesets as well. This also allows you to get around having to deploy a custom work item policy as Bryan described in his suggestion.
I might have some sample code to get you started with traversing the merge history tree if you want to contact me at http://www.edsquared.com
