The WorkingDirectory option does not support relative paths

[Bartleby2718]

The following code works fine on LINQPad on Windows:

void Main()
{
	Command.Run(
		@"C:\Program Files\dotnet\dotnet.exe",
		new[] { "--version" })
		.GetOutputAndErrorLines()
		.Dump();
}

but the following fails:

void Main()
{
	Command.Run(
		@".\dotnet.exe",
		new[] { "--version" },
		o => o.WorkingDirectory(@"C:\Program Files\dotnet\"))
		.GetOutputAndErrorLines()
		.Dump();
}

Is this a bug or an expected behavior?
