Move to a single solution file containing all of the C# projects, but no other solution folders - it's easier to edit those files outside VS than keep adding and removing them from the project.
The AddressBook protos have been regenerated (with a change to the example proto which I haven't included in this change - I'll wait for us to decide exactly what we're doing with namespaces before changing protos outside the csharp directory.
Note that now we've got Addressbook.cs which contains AddressBook and Addressbook classes. It's bad enough that we've got a class called AddressBook within a namespace of AddressBook (hard to get away from) but having things vary just by case is nasty.
This is more evidence that an option for renaming the file and descriptor class would be welcome. (A single option can probably handle both.)
This could potentially be added back in later, but its use is limited and it's a pain in terms of support in PCL environments.
One use that has been highlighted is passing objects between AppDomains; we'd recommend passing a byte array explicitly and reparsing on the other side.
1) Project files for different configurations - we're going to look at all this again, ideally to just have a single PCL-compatible build
2) ProtoGen - the C++ generator is now the only one we care about
3) Proto files - these are mostly duplicates (or older versions) of the ones in the common directories
This is less ideal from a dex count perspective because it requires a
new variable for each message, and because most apps have proguard
rules that will ensure that CREATOR classes are retained.
However, it is required to be able to use nano protos inside of AIDL
files, as the autogenerated AIDL code fails to compile otherwise. This
is a substantial benefit as it allows for backwards-compatible
parameters and return types in AIDL methods along the lines of
safeparcel.
Bug: 19084705

When a MessageNano containing a String is serialized into a buffer that
is too small to contain it, and the buffer's boundary happens to be
where the string field's length delimiting varint is serialized,
and the string's length and 3*length have the same length when
encoded as a varint, an IllegalArgumentException is thrown rather than
an OutOfSpaceException.

It turns out dex (apparently) was inlining these protected final
methods from ExtendableMessageNano into every message class. Removing
these methods from the base class and inlining their code reduces
the method count by 2 methods / message when the store_unknown_fields
option is on.

I wasn't able to get the clear() method to inline into the
constructor when optimizations are on in proguard. As a result,
every message has an extra superfluous kept method assuming the
app never uses clear() directly.
There are a couple of instances where setting this option false is
necessary in order to get code dexing successfully without hitting
the method limit, e.g. https://goto.google.com/tltzq
In this example, I tried turning on the method/inlining/unique and
method/inlining/short optimizations before resorting to adding the
generate_clear option, but the method count did not decrease. The
clear() methods were contributing over a thousand extra methods.

@IntDef is a support library annotation which allows build tools to
determine the valid set of values for a given integer field when that
field is intended to be restricted like an enum. This avoids the
overhead of enums while still allowing for compile-time type checking
in most circumstances.

When building, some instances expect createMessageTyped to have the signature
(int, Class, long), while others expect (int, Class, int). Simply having
the former signature meant that builds expecting the latter would fail.
This is a cherrypick of change b2a9d4321578139677c146ce37eba5e27e8f5c79
from master.

https://android-review.googlesource.com/#/c/67890/ removed field
initialization from the ctor, making it just call clear() instead.
When I added the generate_clear option back (as part of the reftypes
compat mode) in https://android-review.googlesource.com/#/c/109530/,
I forgot to ensure that what clear() used to do was inlined in the
constructor.
This change fixes NPEs that are happening for users of
reftypes_compat_mode who rely on unset repeated fields being empty
arrays rather than null.

Measuring the serialized size of nano protos is now a zero-alloc operation, and serializing a proto now allocates no memory (other than the output buffer) instead of O(total length of strings).

Previously, extensions with field numbers greater than 268435455 would
result in a compile time error in generated code that looks something
like this:
Foo.java:3178: error: integer number too large: 3346754610
3346754610);
This is because we were trying to represent the tag number (an
unsigned int) using a java int constant, but java int constants are
signed, and can't exceed Integer.MAX_VALUE.
Fixed by declaring it as a long instead, and casting it down to an
int in the implementation. This is safe, because the tag value always
fits in 32 bis.

(Having regenerated descriptor.proto relative to src, the earlier commented-out code checking that dependencies match may now be okay to uncomment again. Will experiment in later CLs.)
This commit includes changes to the C#-specific protos, and rebuilt versions of the "stock" protos.
The stock protos have been locally updated to have a specific C# namespace, but this is expected to change soon, so hasn't been committed.
Four areas are currently not tested:
1) Serialization - we may restore this at some point, possibly optionally.
2) Services - currently nothing is generated for this; will need to see how it interacts with GRPC
3) Fields beginning with _{digit} - see https://github.com/google/protobuf/issues/308
4) Fields with names which conflict with the declaring type in nasty ways - see https://github.com/google/protobuf/issues/309
1) Remove CSharpOptions
2) A new version of DescriptorProtoFile (with manual changes from codegen - it would otherwise be Descriptor.cs)
3) Turn off CLS compliance (which we'll remove from the codebase entirely; I don't think it's actually relevant these days)
4) Add "public imports" to FileDescriptor, with code broadly copied from the Java codebase.
Lots more changes to commit before it will build and tests run, but one step at a time...
1. make google/protobuf/stubs/pbconfig.h before making protoc, otherwise it
won't build a freshly checked-out code.
2. Document the build environments that have been tested to work.
3. Add support for MINGW64
