Protobuf: repeated should emit set accessors

Question

.Net

The protobuff compiler generates a class in which repeated fields are read-only.

How to make them { get; set; }?

Let's say I have this proto code:

syntax = "proto3";

option csharp_namespace = "gRPC";

service MyService{
    rpc Foo(Request) returns (Response);
}

message Response{
    repeated string value = 1;
}

message Request{
    string id = 1;
}

Protobuff compiler generates this:

public pbc::RepeatedField<string> Value {
      get { return value_; }
    }

How to make him generate something like this:

public pbc::RepeatedField<string> Value {
      get { return value_; }
      set {
        value_ = pb::ProtoPreconditions.CheckNotNull(value, "value");
      }
    }
