.SYNOPSIS
Builds this repository.

.DESCRIPTION
This build script installs required tools and runs an MSBuild command on this repository.
This script can be used to invoke various targets, such as targets to produce packages,
build projects, run tests, and generate code.

.PARAMETER CI
Sets up CI specific settings and variables.

.PARAMETER Restore
Run restore.

.PARAMETER NoRestore
Suppress running restore on projects.

.PARAMETER NoBuild
Suppress re-compile projects. (Implies -NoRestore)

.PARAMETER NoBuildDeps
Do not build project-to-project references and only build the specified project.

.PARAMETER NoBuildRepoTasks
Skip building eng/tools/RepoTasks/

.PARAMETER Pack
Produce packages.

.PARAMETER Test
Run tests.

.PARAMETER Sign
Run code signing.

.PARAMETER Configuration
Debug or Release

.PARAMETER Architecture
The CPU architecture to build for (x64, x86, arm). Default=x64

.PARAMETER Projects
A list of projects to build. Globbing patterns are supported, such as "$(pwd)/**/*.csproj"

.PARAMETER All
Build all project types.

.PARAMETER BuildManaged
Build managed projects (C#, F#, VB).
You can also use -NoBuildManaged to suppress this project type.

.PARAMETER BuildNative
Build native projects (C++).
This is the default for x64 and x86 builds but useful when you want to build _only_ native projects.
You can use -NoBuildNative to suppress this project type.

.PARAMETER BuildNodeJS
Build NodeJS projects (TypeScript, JS).
You can also use -NoBuildNodeJS to suppress this project type.

.PARAMETER BuildJava
Build Java projects.
You can also use -NoBuildJava to suppress this project type.

.PARAMETER BuildInstallers
Build Windows Installers. Required .NET 3.5 to be installed (WiX toolset requirement).
You can also use -NoBuildInstallers to suppress this project type.

.PARAMETER BinaryLog
Enable the binary logger

.PARAMETER ExcludeCIBinarylog
Don't output binary log by default in CI builds (short: -nobl).

.PARAMETER Verbosity
MSBuild verbosity: q[uiet], m[inimal], n[ormal], d[etailed], and diag[nostic]

.PARAMETER MSBuildArguments
Additional MSBuild arguments to be passed through.

.PARAMETER RuntimeSourceFeed
Additional feed that can be used when downloading .NET runtimes and SDKs

.PARAMETER RuntimeSourceFeedKey
Key for feed that can be used when downloading .NET runtimes and SDKs

.EXAMPLE
Building both native and managed projects.

    build.ps1

or

    build.ps1 -BuildManaged

or

    build.ps1 -BuildManaged -BuildNative

.EXAMPLE
Build only native projects.

    build.ps1 -BuildNative

.EXAMPLE
Building a subfolder of code.

    build.ps1 -projects "$(pwd)/src/SomeFolder/**/*.csproj"

.EXAMPLE
Running tests.

    build.ps1 -test
