.SYNOPSIS
Microsoft Azure IoT SDK .NET build script.

.DESCRIPTION
Builds Azure IoT SDK binaries.

Parameters:
    -configuration {Debug|Release}
    -sign: (Internal use, requires signing toolset) Signs the binaries before release.
    -package: Packs NuGets
    -clean: Runs dotnet clean. Use `git clean -xdf` if this is not sufficient.
    -build: Builds projects (use if re-running tests after a successful build).
    -unittests: Runs unit tests
    -prtests: Runs all tests selected for PR validation
    -e2etests: Runs E2E tests. Requires prerequisites and environment variables.
    -stresstests: Runs Stress tests.
    -publish: (Internal use, requires nuget toolset) Publishes the nuget packages.
    -verbosity: Sets the verbosity level of the command. Allowed values are q[uiet], m[inimal], n[ormal], d[etailed], and diag[nostic].
    -framework: Select which framework to run tests on. Allowed values examples include, but are not limited to, "netcoreapp3.1", "net47", "net451"
    -skipIotHubTests: Provide this flag if you want to skip all IoT Hub integration tests
    -skipDPSTests: Provide this flag if you want to skip all DPS integration tests
	

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 -configuration Release -build

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

Builds and runs unit tests (requires prerequisites).
.EXAMPLE
.\build -configuration Release -sign -package -e2etests

Runs E2E tests with already built binaries.
