Well it's certainly a welcome development that in C# 6.0 you'll be able to give 'automatic' properties a default value in the same way as you can give fields default values just now. However the final version of that (and Visual Studio 2015) is still some time away. In the meantime all you can do is to give automatic properties a default value in the constructor: class MyClass { public int MyInteger {get; set;} public MyClass() { MyInteger = 12345; } } Notice that if you try to do something similar in a struct: struct MyStruct { public int MyInteger {get; set;} public MyStruct(int i) { MyInteger = i; } } you'll get these compiler errors: error CS0188: The 'this' object cannot be used before all of its fields are assigned to error CS0843: Backing field for automatically implemented property 'MyStruct.MyProp' must be fully assigned before control isreturned to the caller. Consider calling the default constructor from a constructor initializer. To fix them you'll therefore have to chain to the default constructor: struct MyStruct { public int MyInteger {get; set;} public MyStruct(int i) : this() { MyInteger = i; } }

Hi Mike Steve  you can also use public int X { get ; set ; } = x ; // C# 6 or higher or private int x= 12345; Public int _X { get{return x;} set{x=value; } }
