How to run setup code only once in an xUnit.net test

The old IUseFixture interface in xUnit.net v1.x has been replaced by two new interfaces: IClassFixture and ICollectionFixture. In addition, the mechanism for injecting fixture values into your tests has changed from property setters to constructor arguments. Class fixtures are created once and shared amongst all tests in the same class (much like the old IUseFixture). Collection fixtures work the same way, except that the single instance is shared amongst all tests in the same test collection.
