.Synopsis
Detects failure from an external script has failed based on both $? and $LASTEXITCODE checking
Tested with a .net console app in 4 modes:
- no stderr, exit 0 (should be the only passing case)
- stderr, exit 0 ($? should indicate failure)
- no stderr, exit 1 ($LASTEXITCODE should indicate failure)
- stderr, exit 1 (both $? and $LASTEXITCODE should indicate failure)
See http://stackoverflow.com/questions/10666101/lastexitcode-0-but-false-in-powershell-redirecting-stderr-to-stdout-gives-n for background

/*
	Creates a blank database suitable for use with TeamCity
	See https://confluence.jetbrains.com/display/TCD9/Setting+up+an+External+Database#SettingupanExternalDatabase-MicrosoftSQLServer

	Important bit is to get the case-sensitive colation correct (_CS_AS),
	which is required for non-Windows build agents (if ever required in future)

// Example of how to interpret SQL server CDC LSNs in C# / .Net
// This is required when polling a server for updates in order to determine
// if a previously stored LSN is still valid (ie > min LSN available)

// Requires .Net 4 (or equivilent BigInteger implementation)
// Sample is a Linqpad script, but you get the idea

// NB: That SQL uses big-endian representation for it's LSNs is not
// (as best I know) something they guarantee not to change
