Cannot add reference (dep) to C# proto library target

[mayerber]

Issue Description

I have the following two targets:

Target 1. C# proto library [full contents in BUILD section below]

csharp_proto_library(
    name = "thing_csharp_proto.dll",
    protos = [":thing_proto"],
    visibility = ["//example/csharp/console:__pkg__"],
)

Target 2. C# console app

csharp_binary(
    name = "console.exe",
    deps = [
        "//example/proto:thing_csharp_proto.dll",
    ]
)

First target thing_csharp_proto.dll builds fine. However, when I add a reference to it (deps) from the console target, build fails with error:

ERROR: /home/neto/repos/github.com/mayerber/bazel-learning/example/csharp/console/BUILD.bazel:6:14: in deps attribute of csharp_binary rule //example/csharp/console:console.exe: '//example/proto:thing_csharp_proto.dll' does not have mandatory providers: ['DotnetAssemblyCompileInfo', 'DotnetAssemblyRuntimeInfo']. Since this rule was created by the macro 'csharp_binary', the error might have been caused by the macro implementation

Looks like csharp_proto_library doesn't implement a couple mandatory providers.
