    Structs cannot contain explicit parameterless constructors. Struct members are automatically initialized to their default values. A default (parameter-less) constructor for a struct could set different values than the all-zeroed state which would be unexpected behavior. The .NET runtime therefore prohibits default constructors for a struct.

Parameterless Constructors in Structure C# 6.0

    Jan 10, 2009 · Rudedog talks about the implementation, but the fundamental reason why structs don't have user-definable parameterless constructors is that the CLR does not want to be obliged to call them, namely during array construction.
