Struct constructor: “fields must be fully assigned before control is returned to the caller.”

by

If you see this error on a struct that has an automatic property, just call the parameterless contructor from your parameterized one by doing : this() example below:

struct MyStruct
{
  public int SomeProp { get; set; }

  public MyStruct(int someVal) : this()
  {
     this.SomeProp = someVal;
  }
}

By calling :this() from your constructor declaration you let the base ValueType class initialize all the backing fields for the automatic properties. We cannot do it manually on our constructor because we don’t have access to the backing field of an automatic property.
ValueType is the base class of all structs.
