.SYNOPSIS
Microsoft Azure IoT SDK .NET build script.

.DESCRIPTION
Builds Azure IoT SDK binaries.

Parameters:
    -clean: Runs dotnet clean. Use `git clean -xdf` if this is not sufficient.
    -nobuild: Skips build step (use if re-running tests after a successful build).
    -nounittests: Skips Unit Tests
    -nopackage: Skips NuGet packaging
    -e2etests: Runs E2E tests. Requires prerequisites and environment variables.
    -stresstests: Runs Stress tests.
    -xamarintests: Runs Xamarin tests. Requires additional SDKs and prerequisite configuration.
    -sign: (Internal use, requires signing toolset) Signs the binaries before release.
    -publish: (Internal use, requires nuget toolset) Publishes the nuget packages.
    -configuration {Debug|Release}
    -verbosity: Sets the verbosity level of the command. Allowed values are q[uiet], m[inimal], n[ormal], d[etailed], and diag[nostic].

Build will automatically detect if the machine is Windows vs Unix. On Windows development boxes, additional testing on .NET Framework will be performed.

The following environment variables can tune the build behavior:
    - AZURE_IOT_DONOTSIGN: disables delay-signing if set to 'TRUE'
    - AZURE_IOT_LOCALPACKAGES: the path to the local nuget source. 
        Add a new source using: `nuget sources add -name MySource -Source <path>`
        Remove a source using: `nuget sources remove -name MySource`

.EXAMPLE
.\build

Builds a Debug version of the SDK.
.EXAMPLE
.\build -config Release

Builds a Release version of the SDK.
.EXAMPLE
.\build -clean -e2etests -xamarintests

Builds and runs all tests (requires prerequisites).
.EXAMPLE
.\build -nobuild -nounittests -nopackage -stresstests

Builds stress tests after a successful build.
