 To use a single container fixture across all tests of a test-assembly (using xUnit.net v3 or an extension), add the `[assembly: AssemblyFixture(typeof(TContainerFixtureEntity))]` annotation referring to your subclass to the assembly. The fixture can then be injected into test class constructors (as shown above), or accessed using the `TestContext.Current.GetFixture<TContainerFixtureEntity>()` method (v3 only) in any test.
