.NET Core CLI task

TFS 2017

Note

The NuGet Authenticate task is the new recommended way to authenticate with Azure Artifacts and other NuGet repositories. The restore and push commands of this task no longer take new features and only critical bugs are addressed.

Azure Pipelines

Use this task to build, test, package, or publish a dotnet application, or to run a custom dotnet command. For package commands, this task supports NuGet.org and authenticated feeds like Package Management and MyGet.

If your .NET Core or .NET Standard build depends on NuGet packages, make sure to add two copies of this step: one with the restore command and one with the build command.

Note

In Microsoft Team Foundation Server (TFS) 2018 and previous versions, build and release pipelines are called definitions, runs are called builds, service connections are called service endpoints, stages are called environments, and jobs are called phases.

versioningScheme
Automatic package versioning
Cannot be used with include referenced projects. If you choose 'Use the date and time', this will generate a SemVer-compliant version formatted as X.Y.Z-ci-datetime where you choose X, Y, and Z.

If you choose 'Use an environment variable', you must select an environment variable and ensure it contains the version number you want to use.

If you choose 'Use the build number', this will use the build number to version your package. Note: Under Options set the build number format to be '$(BuildDefinitionName)_$(Year:yyyy).$(Month).$(DayOfMonth)$(Rev:.r)'
Options: off, byPrereleaseNumber, byEnvVar, byBuildNumber,

arguments
Arguments

The path to the csproj file(s) to use. You can use wildcards (e.g. **/*.csproj for all .csproj files in all subfolders), see file matching patterns.
noCache
Disable local cache
Prevents NuGet from using packages from local machine caches.
restoreArguments
Restore arguments
Write the additional arguments to be passed to the restore command.

Argument aliases: packagesToPack
configurationToPack
Configuration to Package
When using a csproj file this specifies the configuration to package.
Argument aliases: configuration
outputDir
Package Folder
Folder where packages will be created. If empty, packages will be created alongside the csproj file.
Argument aliases: packDirectory
nobuild
Do not build
Don't build the project before packing. Corresponds to the --no-build parameter of the `build` command.
includesymbols
Include Symbols
Additionally creates symbol NuGet packages. Corresponds to the --include-symbols command line parameter.
includesource
Include Source
Includes source code in the package. Corresponds to the --include-source command line parameter.
publishWebProjects
Publish Web Projects
If true, the projects property value will be skipped and the task will try to find the web projects in the repository and run the publish command on them. Web projects are identified by presence of either a web.config file or wwwroot folder in the directory. In the absence of a web.config file or wwwroot folder, projects that use a web SDK, like Microsoft.NET.Sdk.Web, are selected. Note that this argument defaults to true if not specified.
zipAfterPublish
Zip Published Projects
If true, folder created by the publish command will be zipped and deleted.
modifyOutputPath
Add project name to publish path
If true, folders created by the publish command will have project file name prefixed to their folder names when output path is specified explicitly in arguments. This is useful if you want to publish multiple projects to the same folder.
publishTestResults
Publish test results
Enabling this option will generate a test results TRX file in $(Agent.TempDirectory) and results will be published to the server.
This option appends --logger trx --results-directory $(Agent.TempDirectory) to the command line arguments.
Code coverage can be collected by adding --collect "Code coverage" to the command line arguments.
testRunTitle
Test run title
Provides a name for the test run
custom

FAQ

Why is my build, publish, or test step failing to restore packages?

Most dotnet commands, including build, publish, and test include an implicit restore step. This will fail against authenticated feeds, even if you ran a successful dotnet restore in an earlier step, because the earlier step will have cleaned up the credentials it used.

To fix this issue, add the --no-restore flag to the Arguments textbox.

In addition, the test command does not recognize the feedRestore or vstsFeed arguments and feeds specified in this manner will not be included in the generated NuGet.config file when the implicit restore step runs. It is recommended that an explicit dotnet restore step be used to restore packages. The restore command respects the feedRestore and vstsFeed arguments.

Why should I check in a NuGet.config?

Checking a NuGet.config into source control ensures that a key piece of information needed to build your project-the location of its packages-is available to every developer that checks out your code.

However, for situations where a team of developers works on a large range of projects, it's also possible to add an Azure Artifacts feed to the global NuGet.config on each developer's machine. In these situations, using the "Feeds I select here" option in the NuGet task replicates this configuration.

Troubleshooting

File structure for output files is different from previous builds

Azure DevOps hosted agents are configured with .NET Core 3.0, 2.1 and 2.2. CLI for .NET Core 3.0 has a different behavior while publishing projects using output folder argument. When publishing projects with the output folder argument (-o), the output folder is created in the root directory and not in the project file’s directory. Hence while publishing more than one project, all the files are published to the same directory, which causes an issue.

To resolve this issue, use the Add project name to publish path parameter (modifyOutputPath in YAML) in the .NET Core CLI task. This creates a sub folder with project file’s name, inside the output folder. Hence all your projects will be published under different subfolder’s inside the main output folder.

steps:
- task: DotNetCoreCLI@2
  displayName: 'dotnet publish'
  inputs:
    command: publish
    publishWebProjects: false
    projects: '**/*.csproj'
    arguments: '-o testpath'
    zipAfterPublish: false
    modifyOutputPath: true

Project using Entity Framework has stopped working on Hosted Agents

The latest .NET Core: 3.0 does not have Entity Framework(EF) built-in. You will have to either install EF before beginning execution or add global.json to the project with required .NET Core SDK version. This will ensure that correct SDK is used to build EF project. If the required version is not present on the machine, add UseDotNetV2 task to your pipeline to install the required version. Learn more about EF with .NET Core 3.0
