How to deploy solution with multiple web projects with VSTS? - asp.net

I have a solution with multiple web-projects and many class libraries.
I want to deploy web-projects to my own VM with installed deployment agents.
Should I create for every web-project separate its own Build and Release Definitions, right?

Obviously, creating separate Build and Release definition for each web project works. But if you want to use one build & release definition, it also can be achieved, and there are many ways.
For example, if you want to use each project artifact, you could use individual project files in the solution to build in Build definition. Or you could copy the file you need for one project in Release definition, etc. In a word, it depends on how do you want to achieve your requirement.

How to configure Jenkins to build a .net framework project when it depends on another .net project ?

I have a project that depends on another project, how can I configure Jenkins to use the reference of that project in the workspace.
For an example, project B depends on a certain set of classes from project A. Jenkins should be aware to build project A first and then B.
The trigger point is when a commit is pushed to the master of project B.
If a project depends upon another project, it is typically part of the same solution and always part of the same source tree. This means the slave will probably have the source already - or if it doesn't, the step that obtains the source needs the workspace mapping updated to not exclude it.
Also, when a project depends upon another project, the reference information includes the path to the referenced project. In the absence of solution file, this is used directly to build the other project with the same configuration (as in Debug/Release).
It's usually best to use a solution file instead of building projects directly as that ensures platform/configuration customisation is honoured as well as determining the correct build order of the projects.
So I got it sorted out. Since my project was based on project reference, the path had to be the same.
Naming the Jenkins project folder same as the dependent project name I referenced solved the issue.
I was under the impression that another workspace can't access another workspace. But it seems to be Jenkins handles it internally when building projects.

You have two ASP.NET projects. One contains a copy of the other's dll, and a reference to it. Can you run the projects on two different servers?

My question is about the necessary proximity of a dll to the project from which it was created. If you have two ASP.NET projects, and you copy the dll created by one of them, into the other project, (for example, putting it in a library folder), and then add a reference to that copy so it can be used, do the two projects need to run on the same server?
Many thanks!
Yes. You can definitely do this. You have to ensure that the referenced dll files are getting copied over. And as they are separate applications, you can easily deploy them on separate servers. Though I am not entirely sure why do you need to add a reference of ASP.NET project to another ASP.NET project. You might be able to achieve sharing of code by creating separate class library project and referring that.

Packing and publishing NuGet packages with .NET CLI in TeamCity

I am trying to create Team City build template which requires minimum customisation, and I want it to play nicely with legacy projects and projects developed with .NET Core/Standard and .NET CLI.
I am stuck with NuGet as there were some considerable changes in how things work.
Earlier we had to create nuspec file to pack project as a NuGet package. At least in that file we could define various package-related properties.
New csproj file format allows us to define all package properties inside itself. That's fine, but how then do we know which projects should be packaged and which should not?
So far our TeamCity's build step Pack NuGet just contained **.nuspec for Specification files: field. The very fact of nuspec file presence served like a flag pack & publish this project.
However, for dotnet pack we need to specify the project. There is no simple way to distinguish 'main' projects from 'auxiliary' ones on which mains depend. (Let us ignore that project-to-project references are currently not supported.)
We either could pack all projects specifying **.*proj (yet in that case we are to know which packages to publish) or we might specify projects explicitly in a build configuration, but I don't like this approach because you must edit build configuration each time new project is added to the solution.
I also considered the option Generate package on build and omit dot net pack step as package is created on build. The only thing left is publishing the packages with dotnet nuget push specifying **/%BuildConfiguration%/*.nupkg.
Unfortunately when starting build against solution without projects with enabled Generate package on build makes TC fail complaining that
Target files not found for pattern "**/Release/*.nupkg"
Hence, I either need another recipe for achieving the required result or an advice how to make TC consider empty result just as a NOP and mark build as successful.
Yet another option is to use nuspec even for new csproj...
Since TeamCity 2017.2 will be available option to associate build configuration with multiple templates. So you will be able to create different templates to create packages for old projects and new .NET CLI projects.
To specify paths for target .NET projects, which should be packaged, you could use build configuration parameters.
To set such parameters during the build you could send in the preceding build step service message. The value of this parameter could be set to the list of target project files which could be selected via script like that: https://stackoverflow.com/a/8153857/305875

TeamCity working directory of dependency?

If you have a project that builds one project before building the next, but the next needs to know the 'path' of the first build, is it possible to get this?
For example:
Project A has Build Configuration A and Build Configuration B.
Build Configuration B has a dependency on Build Configuration A. From without the Build Configuration B it will need access to the path of Build Configuration A. Is there are a way to obtain this?
Most simple approach would be to define a custom checkout directory in the A and use the same hard-coded value in B.
If you use TeamCity snapshot or artifact dependencies, you can use %dep.btXXX.teamcity.build.checkoutDir% to get checkout directory of the dependency build. However, this will not work in 6.5.0-6.5.5 TeamCity versions, see details and workaround in the issue TW-18715.
However, you should really avoid accessing checkout directory of one build from another. If you need sources of A, you can checkout them in B; if you output of the A's build, then publishing the output as build's artifacts and then using TeamCity artifact dependencies is the way to go. In both cases additionally using TeamCity snapshot dependencies will ensure both builds use the same sources snapshot which is probably what you need.
If you have one agent, and only ever one agent then you could try and use the path from a previous build.
I wouldn't recommend doing this however because if you had two agents, or scaled up in the future to two agents, then it is possible your projects will be built on different agents; this would mean your dependency working directory won't be on the same machine, or it will be outdated as the latest was built elsewhere.
I assume you're after the path of the first build to get its output?
If so, the method we use to share dependencies between projects is to checkin the output from each project into our source control, then every project that requires the output simply has to check them out.

Structure of NAnt build scripts and solution structure on build server

We're in the process of streamlining/automating build, integration and unit testing as well as deployment.
Our software is developed in Visual Studio where we have use both C# and VB.NET in our projects. A single project can be contained within multiple solutions (i.e. Utils project is used in both ProductA and ProductB solutions)
For historical reasons our code repository isn't as well structured as one could have hoped for.
E.g. Utils project might be located under ProductA solution (because that's were it was first used) but it was later deemed useful for productB development and merely just included into the solution of productB (but still located in a subdirectory of productA).
I would like to use continous integration testing and have setup a CC.NET build server where I intend to use NAnt for creating the actual builds.
Question 1: How should I structure my builds on the buildserver? Should I instruct CC.NET to retrieve all the projects for productB into a single library e.g. a file structure similar to
-ProductB
--Utils
--BetterUtils
--Data
or should I opt for a filestructure similar to this
-ProductA
--Utils
-ProductB
--BetterUtils
--Data
and then just have the NAnt build scripts handle the references? Our references in VS doesn't match the actual location in the code repository so it's not possible today to just check-out productB solution and build it straight away (unfortunately). I hope this question makes sense?
Question 2: Is it better to check out all the source code located in different projects into a single file folder (whilst retaining some kind of structure) and then build every thing at once or have multiple projects in CC.NET and then let the CC.NET server handle dependencies?
Example:
Should I have a seperate project in CC.NET for monitoring the automated build/test of Utils project when it's never released on it's own? Or should I just build/test it whilst building it as part of ProductB?
I hope the above makes sense and that you can provide me with some arguments for using either option. We're nowhere near an ideal source code repository structure and I would prefer if I can resolve the lack of repository structure on the build server instead of having to clean up the structure of our repository.
Switching away from VSS is (unfortunately) not an option.
Right now our build consists of either deploying via VS clickonce or pressing F5 so just getting the build automated would be a huge step up for us.
Thanks
To answer your first question, I would recommend a separate top-level folder for each build project. The problem with having a single tree matching your source repository is that when your build server is trying to run multiple builds at once, one or more will likely fail due to files in use by other processes. Also, you may run into cases where a build script is pulling an older version of the code. In that instance you don't want a different project to accidentally use the incorrect source version.
If your solutions already reference projects from relative paths, you may end up with a structure like this:
-CCNetBuilds
--ProductASource
---Utils
---...
--ProductBSource
---ProductA
----Utils
---ProductB
----BetterUtils
----Data
In this case, the build for Product B contains part of the Product A source, at the same relative path as your solution already expects. This takes a bit more time to set up in CC.Net, but makes it easier to maintain if the developers have their code set up this way on their machines. The same solution files used in development are used by the build server.
To answer your second question, I prefer Utilities being its own build. If I have unit tests on my Utilities assembly, I would not want them to run for every single product that uses the Utilities. Also, if you have a separate build for Utilities, you can set a dependency in CC.Net so that Product A and B will not attempt to build if the Utilities build is broken. This provides a bit faster feedback that something is wrong.
