TFS Build Definitions convert to script or version the build definitions - tfs

In TFS, I want to treat build definitions as a code that I can also check-in to some repository. This will benefit tracking deltas in case the build definitions got updated and is no longer in a working state. Also having it in a script provides me the option to run the script locally.
Is that possible in TFS? In practice, I prefer writing the builds,packaging, and deploy code via powershell. I am able to reuse my powershell scripts but I find creating build definitions sometimes easy but I was hoping that after I create the build definitions/steps, I can somehow extract it to a powershell script.

There is no built-in capability for that at the moment. The closest you can get is to use the REST API to extract the build JSON and then set up a CI/CD trigger to update the build definition using the REST API. It's not ideal. I agree with your approach.
There is a proposal to use YAML for exactly this purpose: https://github.com/Microsoft/vsts-tasks/blob/master/docs/yaml.md

TFS 2017 Build Numbering

We have upgraded from TFS 2013 to TFS 2017, One feature we are trying to implement that we had in 2013 was the ability to have a custom build number. the previous method we had a file called BuildVersion.XML which during the first build step would read the major,minor, and revision and name the build with that build number + 1 on the revision. It would then change then checkout and update the revison number and check in the new version. I know that there are steps where people update the AssemblyInfo. The issue is that not all our code is .net apps. we also now have SSIS Packages, Cordova iOS/android apps, angular sites, aws Lambda functions with node.js which do not have the concept of AssemblyInfo. is there an easy way to implement this?
You can do exactly the same thing in Team Build in TFS 2017.
You can update the build number from any task by calling:
Write-Verbose -Verbose "##vso[build.updatebuildnumber]1.2.3.4"
Add a PowerShell task and add an inline script to read from your file and update the build number with the above.
You can then have additional scripts that use the build number any way you need to version your application.
You can see the full list of logging commands here
https://github.com/Microsoft/vso-agent-tasks/blob/master/docs/authoring/commands.md
You can use my VSTS TFVC tasks to interact with source control, though I do not recommend it. I built these tasks for clients of mine who were doing exactly what you are doing.
Instead of relying on a file in source control it would be a much better solution to pass the BuildNumber from the Build Definition along to the build, have one of your first steps update the files on disk with the correct version number then run your build.
If you manipulate files during the build and check them in you run the risk of inconsistent numbering when you scale up to multiple build agents, it's hard to use in combination with parallel builds and build variable multiplexing and it becomes notoriously hard to do Gated Checkins and Shelveset builds. Plus, it limits your options to move to Git in the future.

Can you ask for user input for TFS 2015 CI build?

This seems simple enough, but I can't find a solution for this online.
I am integrating SonarQube into our build definitions that get triggered on check in. I want the version SonarQube uses to be tied back to the project number defined by the business side of things.
Ideally, I would like to be able to prompt the user for input. When you go to check in and it kicks off the build, it would ask you for the project number to be used as the version for SonarQube. Is this something TFS 2015 supports?
User input for build definitions
As far as I know, build definitions that are not manually triggered do not prompt for user input. A prompt allowing users to set build variables is shown for manually triggered builds from the VSTS web page.
SonarQube project version
I would recommend against you using the build or assembly version in your build tasks. This is because the SonarQube concept of version is quite different from the build concept. SonarQube uses versions as a baselining mechanism / to determine the leak period. If you up the version number often, the leak period is going to be too short to be actionable.
I'd recommend keeping the SonarQube project version in sync with your release schedule instead.
The short answer to this question is no, there is no way to prompt for input on a non-manually triggered CI build.
Here's what we did to work around this:
I wrote a Powershell script to read a config file and set the values to environment variables exposed to later build steps. Those variables are then what are specified in the Sonar Begin Analysis build task. I packaged that script up as a custom build task that will read a "sonar.config" file. This means all we have to do is add a "sonar.config" file to each solution we want to run Sonar analysis for, defining the key, name and version for the project, and then this build task will populate all necessary environment variables as the first step in the build.
So not a perfect solution, but it gets the job done without us having to add a lot of extra code to our solutions.

Jenkins with many solutions in one repository

I am trying to setup Jenkins to automate a build. We have one enormous repository with approximately 100 solution files. To build this repository we have a build program which finds all the solutions and builds in a specified order.
I would like to change that to use Jenkins. Is there a way to setup msbuild and specify a build order for all of these solution files?
p.s. I am trying to avoid creating one mammoth solution file which contains all of the projects.
If in fact all of your projects use ProjectReferences to other VS projects, you should be able to use MSBuild to extract all those references via the ResolveProjectReferences MSBuild task. You can then build an MSBuild script build those dependent projects in order. There's a pretty good example of this here. The example given there goes so far as constructing a specialized MSBuild task that builds a dependency graph, which I must say is pretty cool.

Is it possible to run a script when a build is tagged in Teamcity?

We are using TeamCity 9.x as are main CI server. I'm looking for ways to run a script (PowerShell, Python, ...) when a build is tagged. Is this possible?
The only thing I can think of is to write a simple service which polls the REST API for the last x builds and reads the <tag/> information.
We are using TFS for source control, so labeling the sources is not an option (because a label is unique in TFS).
Are there any other (simpler) ways to do this? Or is there any other way to define build quality and execute something?
Yes you can
In the build trigger definition, you can mention specific subset of tags(using regex patterns) on which teamcity targets are trigeered. In your case, you have to set the triggers to run on tags only
I know this doesn't answer your question but figured I'd mention it anyways since you have TFS in your environment already.
If you were using TFS Build it has a drop down on each build to indicate quality. And there's a free tool called TFS Deployer that allows you to run scripts when the quality is changed.

TFS 2010 custom build step

I am playing with TFS 2010, and am trying to setup a build process that will have some custom steps.
These include things like, stopping/starting IIS, search and replace files etc... across environments.
I have tried to look for examples online and have not found anything clear and meaningful on how to just run a script or something over the source files. Looking at the default build process template (DefaultTemplate.xml) I cant make much sense of it.
How do I go about doing this ?
For info on customising the TFS2010 workflow build templates have a look at Ewald Hoffman's series. Start with Part 1 (archived here).
I should also mention that since it looks like you're doing deployment then you may want to break deployment automation away from build automation.
This is almost exactly what I'd say for this question (Split build and deplyment stages, investigate TFSDeployer). One additional element is more generic - for deployment tasks you can't find an easy integrated tool you should create a custom deployment script. You can call any script by adding an "InvokeProcess" step in your Build workflow. TFSDeployer also has locations where you can insert custom PowerShell Scripts. (If you don't like PowerShell you can have PowerShell or "InvokeProcess" call a different script engine.)
