ant-contrib’s Variable task can do this: <property name=”x” value=”6″/> <echo>${x}</echo> <!– will print 6 –> <var name=”x” unset=”true”/> <property name=”x” value=”12″/> <echo>${x}</echo> <!– will print 12 –> Not recommended, though, it can lead to weird side-effects if parts of your Ant scripts assume immutable property values, and other parts break this assumption.

1.) There is a difference between method and function property declaration: interface InterfaceA { doSomething(data: object): boolean; // method declaration } interface InterfaceB { doSomething: (data: object) => boolean; // function as property declaration } 2.) TypeScript 2.6 introduces a compiler flag for stronger-typed, sound function types: Under –strictFunctionTypes function type parameter positions are checked … Read more
As others have said, you are looking for the .AsReadOnly() extension method. However, you should store a reference to the collection instead of creating it during each property access: private readonly List<SomeOtherClass> _items; public WhatClass() { _items = new List<SomeOtherClass>(); this.Items = _items.AsReadOnly(); } public ReadOnlyCollection<SomeOtherClass> Items { get; private set; } This is to … Read more
