YDeliver is a (opinionated) build and deployment framework aimed at .NET projects.

YDeliver is based on Powershell and the amazing psake framework. It borrows the best practices ( for example, Ydeliver strongly believes in convention over configuration) and tricks from across the industry, with the aim of quickly bootstrapping the build and release process of typical .NET projects.

Getting Started

You can include YDeliver as submodule within your project (recommended), or just have it as a Powershell module in your machine to invoke builds off.

Import-Module path\to\YDeliver

You can also install YDeliver as a solution-level package using Nuget / Package manager:

Install-Package ydeliver


YBuild is the build component of YDeliver. Typically, this component is for compiling, unit testing and packaging your artifacts. YBuild comes with prebuilt tasks to clean and compile your solution, run NUnit tests and package ( zip / nuget) up your artifacts.

For example, you can run the clean, compile and package tasks by doing

Invoke-YBuild Clean,Compile,Project

To get a list of available tasks, you can do:

Invoke-YBuild -listAvailable

You can override the build.yml settings by adding a -config parameter to Invoke-YBuild. See scaffolded build.ps1 for example.


YInstall component takes care of "installing" the build artifacts - be it zip files, installers, nuget packages etc.

You can install "applications". These can be certain modules within your project - like a service, web app etc or the entire project itself. Each applications is defined to be of certain tasks and the configurations needed to install them. For example:

    artifactsDir: "$rootDir/build"

                    packages: ["ydeliver.*.nupkg"]
                    source: "NuGet official package source"

The above configuration in a install.yml defines an application ydeliver. When you install this application, the task NugetPublish is run. The config section defines the configuration needed to run the tasks. Here the nuget packages and the nuget feed source are specified.

You can override the install.yml settings by adding a -config parameter to Invoke-YInstall. See scaffolded install.ps1 for example.


Coming soon.


YDeliver follows certain conventions, like where to pick up the solution file, how to recognize unit test dlls, etc. These conventions are specified under Conventions\Defaults.ps1

You can specify your own, or modify the ones provided by the framework by adding the conventions key in the component config ( like build.yml):

    framework:  "3.5x86"
    solutionFile:   "$rootDir/name.sln"

Custom Tasks

If you cannot add your own task directly into the component's task folder ( either because you are using YDeliver as a Nuget package and don't want to touch the installed files, or if your are using YDeliver as a submodule), you can add a file in your project root named <action>.custom.tasks.ps1 and the tasks from it will be picked up as well.

For example, if you want to add custom tasks for YBuild, create a file named build.custom.tasks.ps1 and place it in the root of your project. These task will now be available from Invoke-YBuild.


You can specify configurations like which folders to package into artifacts, which projects to make nuget packages out off etc.


Specifies the configurations for YBuild

copyContents : For specifying files and folders to be copied from one place to another packageContents : For specifying file and folders to be packages into zip files nugetSpecs : For specifying the .nuspec files to be used to build nuget packages

Sample build.yml:

    "$buildPath/cmd.dll":   "$buildPath/Cmd"
    "$buildPath/cmd.pdb":   "$buildPath/Cmd"
    "$buildPath/test":      "$buildPath/Cmd"

    "$buildPath/Cmd":  "Cmd.zip"

nugetSpecs:   [cmd.nuspec]

##YFlow (work in progress)

YFlow is the developer workflow component. During the course of development, the developers would be running specific tasks at specific times. For example, you may want to run the dbdeploy task after updating some migrations. You may want to index solr after updating the config etc. Probably, when you run dbdeploy, you also want to reindex solr. Sometimes, these tasks may also cut across components ( YBuild, YInstall).

If you are not using workflows, you may have to do:

Invoke-YBuild dbdeploy
Invoke-YInstall solr

With YFlow, you can define these as your workflows. Scaffold the component to get workflow.ps1 and workflows.yml.

Invoke-YScaffold YFlow

workflow.yml for the above scenario will look like this:

        ybuild: [dbdeploy]
        yinstall: [solr]

Now, you can do:

Invoke-YFlow dbsolr #or
.\workflow.ps1 dbsolr

You can merge the functionalities of build.ps1 and workflow.ps1 as appropriate.

Note that YDeliver doesn't encourage dependencies between task as specified using psake syntax. We believe it is better being explicit. YFlow may be the replacement for this.


This component helps you to quickly bootstrap a project's build and deploy. You can scaffold the files and scripts that are used by the different YDeliver component.

Invoke-YScaffold -Component YBuild

YScaffold will not replace files that already exist unless called with the -Force switch.

What's ahead?

Lots more documentation. Bringing in the deploy component.
