Component Build Status
Management Libraries Build Status

Prerequisites:

GENERAL THINGS TO KNOW:

Client Libraries are sdks used to interact with azure resources at application run time while Management Libraries are those used to manage (create/modify/delete) Azure resources.

Build Repo : To build all Client and Management libraries together. Invoke dotnet build build.proj from the root of the repo.
To scope to a single service supply a scope property e.g. dotnet build build.proj /p:Scope=servicebus. This will build both client and management projects in the specified service. If using msbuild you must run restore first. See below for how to build the client or management libraries independently.

Path Length : To account for the 260 characters Path Length Limit encountered on windows OS, file paths within the repo is keep below 210 characters. This gives you a runway of 49 characters as clone path for your repo. Paths longer that 260 characters will cause the build to break on windows OS and on CI. Assuming you clone to the default VisualStudio location such that the root of your clone is C:\Users\\**USERNAME**\Source\Repos\azure-sdk-for-net your username will have to be 9 characters long to avoid build errors caused by long paths. Consider using C:\git as you clone path.

Dependencies : To ensure that the same versions of dependencies are used for all projects in the repo, package versions are managed from a central location in eng\Packages.Data.props. When adding package references you should first ensure that an Update reference of the package with the version exist in the Packages.Data.props then Include the reference without the version in your .csproj. Contact [email protected] if you need to change versions for packages already present in Packages.Data.props

Line Endings : If working on windows OS ensure git is installed with Checkout Windows-style, commit Unix-style option or core.autocrlf set to true in git config. If working on Unix based Linux or MacOS ensure git is installed with Checkout as-is, commit Unix-style option or core.autocrlf set to input in git config

Management Libraries

TO BUILD:

  1. Open any solution, eg "SDKs\Compute\Microsoft.Azure.Management.Compute.sln"
  2. Build solution from Visual Studio

Single Service from Command Line

  1. Open VS 2019 command Prompt
  2. From the root directory
  3. Invoke msbuild eng\mgmt.proj /p:scope=Compute

Build without any scope will build all management SDK's.

Create single nuget package

In order to build one package and run it's test msbuild eng\mgmt.proj /t:CreateNugetPackage /p:scope=Compute Nuget package will be created in root directory under \artifacts\packages\Debug (default configuration is Debug)

TO TEST:

Using Visual Studio:

  1. Build project in Visual Studio.
  2. Test Explorer window will get populated with tests. Select test and Run or Debug

Using the command line:

Run e.g. msbuild eng\mgmt.proj /t:"Runtests" /p:Scope=Compute In the above example RunTests will build and run tests for Compute only or you can use command line CLI dotnet test Compute\Microsoft.Azure.Management.Compute\tests\Microsoft.Azure.Management.Tests.csproj

Non-Windows command line build

Now you can use the same command on non-windows as above for e.g. on Ubuntu you can do something like below:

  • dotnet msbuild eng\mgmt.proj /t:Build /p:scope=Compute
  • dotnet msbuild eng\mgmt.proj /t:RunTests /p:scope=Compute
  • dotnet msbuild eng\mgmt.proj /t:CreateNugetPackage /p:scope=Compute
  • dotnet msbuild build.proj /t:Util /p:UtilityName=InstallPsModules

Update build tools

Build tools are now downloaded as part of a nuget package under root\restoredPackages\microsoft.internal.netsdkbuild.mgmt.tools If for any reason there is an update to the build tools, you will then need to first delete directory root\restoredPackages\microsoft.internal.netsdkbuild.mgmt.tools and re-execute your build command. This will simply get the latest version of build tools.

Client Libraries

TO BUILD:

Single Service from Command Line

  1. Open VS 2019 Command Prompt
  2. Navigate to service directory e.g. "sdk\eventhub"
  3. Invoke dotnet build
  4. or Build the service.proj in the repo root, passing the directory name of the specific service as a property. e.g. dotnet build eng\service.proj /p:ServiceDirectory=eventhub

Single Service from Visual Studio

  1. Open any data-plane solution e.g. "sdk\eventhub\Microsoft.Azure.EventHubs.sln"
  2. Build solution from Visual Studio

All Client Services from Command Line

  1. Open VS 2019 Command Prompt
  2. Navigate to repository root directory
  3. Invoke dotnet build eng\service.proj

TO TEST:

Single Service from Command Line

  1. Open VS 2019 Command Prompt
  2. Navigate to service directory e.g. "sdk\eventhub"
  3. Invoke dotnet test --filter TestCategory!=Live (Skips live tests)
  4. or run test against service.proj in the repo root, passing the directory name of the specific service as a property. e.g. dotnet test eng\service.proj /p:ServiceDirectory=eventhub --filter TestCategory!=Live

Single Service from Visual Studio

  1. Build.
  2. Test Explorer window will get populated with tests. Select test and Run or Debug

All Client Services from Command Line

  1. Open VS 2019 Command Propmpt
  2. Navigate to repository root directory
  3. Invoke dotnet test eng\service.proj --filter TestCategory!=Live

Public API changes

If you make a public API change eng\Export-API.ps1 script has to be run to update public API listings.

On-boarding New Libraries

Project Structure

In sdk\< Service Name >, you will find projects for services that have already been implemented

  1. Client library projects needs to use the $(RequiredTargetFrameworks) (defined in eng/Directory.Build.Data.props) property in its TargetFramework while management library projects should use $(SdkTargetFx) (defined in AzSdk.reference.props)
  2. Projects of related packages are grouped together in a folder following the structure specified in Repo Structure
    • Client library packages are in a folder name like Microsoft.Azure.< ServiceName >
    • Management library packages are in a folder named like Microsoft.Azure.Management.< Resource Provider Name >
  3. Each shipping package contains a project for their generated and /or Customization code
    • The folder 'Generated' contains the generated code
    • The folder 'Customizations' contains additions to the generated code - this can include additions to the generated partial classes, or additional classes that augment the SDK or call the generated code
    • The file generate.cmd, used to generate library code for the given package, can also be found in this project

Standard Process

  1. Create fork of Azure REST API Specs
  2. Create fork of Azure SDK for .NET
  3. Create your Swagger specification for your HTTP API. For more information see Introduction to Swagger - The World's Most Popular Framework for APIs
  4. Install the latest version of AutoRest and use it to generate your C# client. For more info on getting started with AutoRest, see the AutoRest repository
  5. Create a branch in your fork of Azure SDK for .NET and add your newly generated code to your project. If you don't have a project in the SDK yet, look at some of the existing projects and build one like the others.
  6. MANDATORY: Add or update tests for the newly generated code.
  7. Once added to the Azure SDK for .NET, build your local package using client or management library instructions shown in the above sections.
  8. A Pull request of your Azure SDK for .NET changes against master branch of the Azure SDK for .NET
  9. The pull requests will be reviewed and merged by the Azure SDK team

New Resource Provider

  1. If you have never created an SDK for your service before, you will need the following things to get your SDK in the repo
  2. Follow the standard process described above.
  3. Project names helps in using basic heuristics in finding projects as well it's associated test projects during CI process.
  4. Create a new directory using the name of your service as specified in azure-rest-api-specs/specification Repo
  5. Follow the the directory structure below
sdk\<service name>\<package name>\README.md
sdk\<service name>\<package name>\*src*
sdk\<service name>\<package name>\*tests*
sdk\<service name>\<package name>\*samples*

e.g.

sdk\eventgrid\Microsoft.Azure.EventGrid\src\Microsoft.Azure.EventGrid.csproj
sdk\eventgrid\Microsoft.Azure.EventGrid\tests\Microsoft.Azure.EventGrid.Tests.csproj
sdk\eventgrid\Microsoft.Azure.Management.EventGrid\src\Microsoft.Azure.Management.EventGrid.csproj
sdk\eventgrid\Microsoft.Azure.Management.EventGrid\tests\Microsoft.Azure.Management.EventGrid.Tests.csproj

*Ensure that your service name is the same as it is specified in the azure-rest-api-specs/specification Repo, that your csproj files starts with Microsoft.Azure* , that test files end with .Tests and that management plane project files contain .Management.

  1. Copy .csproj from any other .csproj and update the following information in the new .csproj

    Project Properties
    AssemblyTitle
    Description
    VersionPrefix
    PackageTags
    PackageReleaseNotes

PackageReleaseNotes are important because this information is displayed on www.nuget.org when your nuget package is published

  1. Copy existing generate.ps1 file from another service and update the ResourceProvider name that is applicable to your SDK. Resource provider refers to the relative path of your REST spec directory in Azure-Rest-Api-Specs repository During SDK generation, this path helps to locate the REST API spec from the https://github.com/Azure/azure-rest-api-specs

Code Review Process

Before a pull request will be considered by the Azure SDK team, the following requirements must be met:

  • Prior to issuing the pull request:
    • All code must have completed any necessary legal signoff for being publicly viewable (Patent review, JSR review, etc.)
    • The changes cannot break any existing functional/unit tests that are part of the central repository.
      • This includes all tests, even those not associated with the given feature area.
    • Code submitted must have basic unit test coverage, and have all the unit tests pass. Testing is the full responsibility of the service team
      • Functional tests are encouraged, and provide teams with a way to mitigate regressions caused by other code contributions.
    • Code should be commented.
    • Code should be fully code reviewed.
    • Code should be able to merge without any conflicts into the dev branch being targeted.
    • Code should pass all relevant static checks and coding guidelines set forth by the specific repository.
    • All build warnings and code analysis warnings should be fixed prior to submission.
  • As part of the pull request (aka, in the text box on GitHub as part of submitting the pull request):
    • Proof of completion of the code review and test passes requirements above.
    • Identity of QA responsible for feature testing (can be conducted post-merging of the pull request).
    • Short description of the payload of pull request.
  • After the pull request is submitted:
    • Our SLA is 48 hours. When your PR is submitted someone on our team will be auto assigned the PR for review. No need to email us
    • MS internal folks, please reach out to us via our Teams channel or
    • Send an email to the Azure Developer Platform team [email protected] alias.
      • Include all interested parties from your team as well.
      • In the message, make sure to acknowledge that the legal signoff process is complete.

Once all of the above steps are met, the following process will be followed:

  • A member of the Azure SDK team will review the pull request on GitHub.
  • If the pull request meets the repository's requirements, the individual will approve the pull request, merging the code into the dev branch of the source repository.
    • The owner will then respond to the email sent as part of the pull request, informing the group of the completion of the request.
  • If the request does not meet any of the requirements, the pull request will not be merged, and the necessary fixes for acceptance will be communicated back to the partner team.

Issues with Generated Code

Much of the management plane SDK code is generated from metadata specs about the REST APIs. Do not submit PRs that modify generated code. Instead,

  • File an issue describing the problem,
  • Refer to the the AutoRest project to view and modify the generator, or
  • Add additional methods, properties, and overloads to the SDK by adding classes in the 'Customizations' folder of a project
