C# Rules

Rule	Description
csharp_proto_repositories	Load WORKSPACE dependencies.
csharp_proto_compile	Generate protobuf source files.
csharp_proto_library	Generate and compiles protobuf source files.

csharp_proto_repositories

Enable C# support by loading the dependencies in your workspace.

IMPORTANT: C# currently requires a forked version of rules_dotnet having support for the new_nuget_package rule found in https://github.com/pcj/rules_dotnet. This will change once these changes are integrated upstream.

git_repository(
    name = "io_bazel_rules_dotnet",
    remote = "https://github.com/pcj/rules_dotnet.git",
    commit = "ed06be64a1df2b446516bf0890bd0b4d41af381a",
)
csharp_repositories(use_local_mono = False) # or true, if you prefer

load("@org_pubref_rules_protobuf//csharp:rules.bzl", "csharp_proto_repositories")
csharp_proto_repositories()

csharp_proto_compile

This is a thin wrapper over the proto_compile rule having language @org_pubref_rules_protobuf//csharp.

load("@org_pubref_rules_protobuf//csharp:rules.bzl", "csharp_proto_compile")

csharp_proto_compile(
  name = "protos",
  protos = ["message.proto"],
  with_grpc = True,
)

$ bazel build :protos
Target //:protos up-to-date:
  bazel-genfiles/Message.cs

csharp_proto_library

Pass the set of protobuf source files to the protos attribute.

load("@org_pubref_rules_protobuf//csharp:rules.bzl", "csharp_proto_library")

csharp_proto_library(
  name = "Helloworld",
  protos = ["message.proto"],
  with_grpc = True,
)

$ bazel build :Helloworld
Target //:Helloworld up-to-date:
  bazel-bin/Helloworld.dll
  bazel-bin/Helloworld.xml

To get the list of required compile-time dependencies in other contexts for grpc-related code, load the list from the rules.bzl file:

load("@org_pubref_rules_protobuf//csharp:rules.bzl", "GRPC_COMPILE_DEPS")

csharp_binary(
  name = "mylib",
  srcs = ['MyApp.cs'],
  deps = [
    ":protolib"
  ] + GRPC_COMPILE_DEPS,
)

Consult source files in the examples/helloworld/csharp directory for additional information.
