TFS2015 vNext missing features - continuous-integration

I have been working with TeamCity, Jenkins and Bamboo my last 8years. Latest 2years very involved in ContinuousIntegration factory setup and mainteinance on my team with very good results, giving me a lot of habits about how to deal with builds, artifacts and pipelines.
Now, i'm on a new company, new team, new CI, TFS2015, first time for me.
Just one month before I arrive to this new team they were on TFS2012, with XAMLs, so I took the migration to vNext builds.
At first look, I found on vNext builds the classic build definition, i mean adding steps as a single task to the build, instead of monolithic XAML file.
But with the time, i was trying to create more complex builds, like TeamCity build chains, but this is not possible, strike one...
Then, I was trying to deal with multiple branches, one continuous build for each branch (we are on TFSVC), create packages from each branch, and I found I was duplicating my builds just to change repository paths and a few details, so I moved builds to templates trying to reuse build definitions, introducing variables to generates paths(for repos and branches) and versions and expecting to change only in one place the build and having this changes reflected in all builds derived from templates... but that's was not the case... :
variables are not accepted everywhere, like in repo paths.
can't change templates after created them, just replace them, and builds created from templates are not affected after template is changed.
strike two ?.....
I'm wondering if maybe I'm doing things wrong with TFS, maybe this is a different system and I can't do things like in other CIs.
Any advice in how to approach TFS to have a good, dynamic and reusable set of builds ??

here isn’t the feature that the changes of a build definition or template affects other existing build definitions.
If the build steps of build definitions are the same for each branch, you just need a build definition and add filters for each branch (Triggers > Continuous integrations (CI), after that it will uses corresponding source to build for CI build, for example, develop branch changes > Trigger a build automatically with develop branch source.
On the other hand, you can change branch and source version when queue build manually or through REST API.
If the build steps are different for each branch, you need to modify the definitions independently for detail requirements.

Teamcity build chain templating

We have set of different web application projects, which is delivered by Teamcity to different environments. At this moment, we are doing all-in-one builds: compile, package and deploy at once; all based on a templates.
Now I am investigating a way to separate concenrs: one build tests and produces package, another - delivers. Naturally, both builds are having own templates. Is there a way to template this build chain - so, when I choose some meta-template - both builds will be created with present Artifact dependencies?
Sadly not. What we've had to do is clone the build chains. We've put in place a mechanism which makes sure the set-ups of the different chains do not diverge.
Another option, admittedly ugly, is to set up a single build chain and let each of your projects pretend that it's a separate VCS branch. In this case there's a single set-up (for the single build chain) and to view the history of a given project you filter by that project "branch". Needless to say, that's not how branches should be used and you may run into some issue down the line.

Build dependencies and local builds with continuous integration

Our company currently uses TFS for source control and build server. Most of our projects are written in C/C++, but we also have some .NET projects and wouldn't want to be limited if we need to use other languages in the future.
We'd like to use Git for our source control and we're trying to understand what would be the best choice for a build server. We have started looking into TeamCity, but there are some issues we're having trouble with which will probably be relevant regardless of our choice of build server:
Build dependencies - We'd like to be able to control the build dependencies for each <project, branch>. For example, have <MyProj, feature_branch> depend on <InfraProj1, feature_branch> and <InfraProj2, master>.
From what we’ve seen, to do that we might need to use Gradle or something similar to build our projects instead of plain MSBuild. Is this correct? Are there simpler ways of achieving this?
Local builds - Obviously we'd like to be able to build projects locally as well. This becomes somewhat of a problem when project dependencies are introduced, as we need a way to reference these resources or copy them locally for the build to succeed. How is this usually solved?
I'd appreciate any input, but a sample setup which covers these issues will also be a great help.
IMHO both issues you mention fall really in the config management category, thus, as you say, unrelated to the build server choice.
A workspace for a project build (doesn't matter if centralized or local) should really contain all necessary resources for the build.
How can you achieve that? Have a project "metadata" git repo with a "content" file containing all your project components and their dependencies (each with its own git/other repo) and their exact versions - effectively tying them together coherently (you may find it useful to store other metadata in this component down the road as well, like component specific SCM info if using a mix of SCMs across the workspace).
A workspace pull wrapper script would first pull this metadata git repo, parse the content file and then pull all the other project components and their dependencies according with the content file info. Any build in such workspace would have all the parts it needs.
When time comes to modify either the code in a project component or the version of one of the dependencies you'll need to also update this content file in the metadata git repo to reflect the update and commit it - this is how your project makes progress coherently, as a whole.
Of course, actually managing dependencies is another matter. Tons of opinions out there, some even conflicting.

Same build definition for different branches

Lets say I have the following branches for my application in TFS2012.
May2013 and June2013.
For deploying these applications I am using TWO different build definitions. One that points to the May20123.sln and one June2013.sln. The builds are doing the exact same thing, only difference pointing to different source code.
I would like to only have one build definition which starts with popup where I can choose which branch to deploy. Is this possible?
(This is just a simple example, the actual scenario is much more complex). I am aware that could change branching strategy...
Thanks!
I do not believe this is possible out of the box, but the Clone build definition feature if TFS 2012 should make your life a lot easier. Simply, create a new branch and then clone an existing build.

Publish a specific revision using CruiseControl.Net

I am setting up a CruiseControl.Net server. So far, it only builds a project (.Net website), and I kind-of know how to set up unit testing, code coverage, etc in the future.
What I will need to have soon is this:
The developers commit changes to SVN continually, thus CCNet builds often.
CCNet will publish the latest version to the development server, as soon as a commit is validated (with unit tests etc).
The project manager validates a specific version, in order to publish it to the pre-production server, and create a SVN tag from this revision.
The last point is where my problem lies: how exactly can I set up things so the project manager can, for instance, browse to the CCNet web dashboard, select a previous specific build, and says "this is the build I want to publish" ?
I believe that my thinking is flawed somewhere, but I can't put my finger on it. Maybe CCNet is not the right place to do these manipulations ?
In my mind, I can create a SVN tag using CCNet, and mostly work from the trunk, but maybe I can't ? Maybe it's the other way around, and I should add a CCNet project every time a tag is created under SVN ?
The final goal is that I want to automate the publication process: zip creation (for archiving), web.config modification (using Nant for instance), and website publication (using FTP).
In all these steps, I want to limit the manual intervention to the maximum. If I can avoid to add a new project to CCNet every time a tag or branch is created in SVN, that would be awesome.
Thanks for your help, and sorry if it's not very easy to read, but it's not very clear in my head either...
Since you can create any task, you should be able to achieve the goal, though unfortunately not out-of-the-box.
Since you use SVN, it all depends actually on revision. I think I'd create a separate project for your third scenario and added a parameter where PM would provide revision number. Then based on that I'd tag sources etc. in my own task.
Regarding the other points, I think this is similar. Recently for web projects we started using MSDeploy, and in each stage build the MSDeploy package was created. Then there was a separate build called Deploy, that when forced allows us to select which package we want to deploy using MSDeploy.
Having several environments, however, started a little bit like overkill for managing with CCNet, and I'll be looking into kwakee at some time.

Branching strategies with maven, teamcity and TFS

I have been tasked with updating our build process right now to be more efficient and I have spent a week reading best practices and strategies but I still have not found a solution for our current problem.
Background
Currently we have one monolithic build/application that really needs to be split apart into at least 4 applications with some shared libraries. We currently do not branch unless we absolutely have to. We have a teamcity build that builds on each check-in to TFS. When we are ready for a release we have a code freeze and only check-in fixes for bugs found in QA. Obviously this is a terrible practice and we have finally gotten approval to change it.
Proposed Solutions
The proposed solution will be to split up the application and have different release cycles for each application, move from ant to maven and branch per release.
Branching - Right now we just have a main trunk in source control. I think we want to branch off the trunk when we are ready for a release, and update the branch for bugs found in QA. When the build is ready to be released, merge the branch changes back into the trunk.
Here is how I was planning on setting up TFS.

Thinking about managing all of the POMs and versions in the POMs seems WAY too difficult right now. I've read up on the maven release plugin, but I'm not sure if it can branch in the way I'm thinking we want to.
Next problem is getting teamcity working. I was thinking of having 3 teamcity projects for each app. A dev project that always points at the trunks, a QA project for testing the QA build and a production project to build changes for hotfixes. Each time a new release comes to QA I would have to update the QA teamcity project to point at the new release branch and update the release build number in teamcity. When that release passes QA I would have to update the production teamcity project to point that the branch that just passed QA and update the build number to the build number that just passed QA.
Surely there is a better strategy that this.
Questions
Where should I be putting these branch folders?
Should QA builds be snapshots still until the build goes to pre-production?
How do you configure teamcity to pick up these branches without changing the sources path for every release?
Should there be parent POMs for each app that the developers use to make sure all of their dependencies are compiled and up to date?
I just want to question your thinking that your applications should be on different release cycles. Modularization is a good thing for code quality but if your modules are on separate release cycles you introduce a lot of overhead. In particular, version management becomes quite a burden and if you get it wrong you can introduce runtime bugs.
How do these separate applications relate to each other? Is there any dependency between them (maybe via a shared library)? Do they communicate with each other? Are they deployed together?
If it is not necessary that they be on separate release cycles then you're probably better off keeping them together.
