Why class fields cannot be var?

I'd like to avoid typing out complex/long type definitions for fields like you can with local variables.

I'd like to know why this couldn't be done?

public class Foo
{
    public var barField = new Dictionary<string, int>(); // Does not work

    public void Method()
    {
        var barLocal = new Dictionary<string, int>(); // Works
    }
}
