Updated build pipeline to use .NET Core 3.1 sdk. (#83)

* Updated build pipeline to use .NET Core 3.1 sdk.

Use powershell core built into .NET Core

Updated build script to no longer specify an output path. Specifying an
output path for a project that targets multiple frameworks causes the
binaries to overwrite each other. This results in a broken build.

Updated build scripts to use whatever version of PowerShell is available in the build environment.

* Removed unused variable.

* Reversed order of PowerShell selection.
