From e38294a62d7f37c0661273a9a26fda16d557423f Mon Sep 17 00:00:00 2001 From: Jon Skeet Date: Tue, 9 Jun 2015 19:30:44 +0100 Subject: First pass at the mutable API. Quite a bit more to do - in particular, it's pretty slow right now. --- csharp/src/ProtocolBuffers/UnknownField.cs | 415 ----------------------------- 1 file changed, 415 deletions(-) delete mode 100644 csharp/src/ProtocolBuffers/UnknownField.cs (limited to 'csharp/src/ProtocolBuffers/UnknownField.cs') diff --git a/csharp/src/ProtocolBuffers/UnknownField.cs b/csharp/src/ProtocolBuffers/UnknownField.cs deleted file mode 100644 index 7650b9df..00000000 --- a/csharp/src/ProtocolBuffers/UnknownField.cs +++ /dev/null @@ -1,415 +0,0 @@ -#region Copyright notice and license - -// Protocol Buffers - Google's data interchange format -// Copyright 2008 Google Inc.
