 If a SimpleRequest has fill_username=true and that request was successfully
 authenticated, then the SimpleResponse should have username filled with the
 canonical form of the authenticated source. The canonical form is dependent on
 the authentication method, but is likely to be a base 10 integer identifier or
 an email address.

+If a SimpleRequest has fill_oauth_scope=true and that request was successfully

+
+Although a general server-side feature, most test servers won't implement this
+feature. The TLS server grpc-test.sandbox.google.com:443 supports this feature.
+It requires at least the OAuth scope

 Ideally, this would be communicated via metadata and not in the
 request/response, but we want to use this test in code paths that don't yet
 fully communicate metadata.

+This directory contains MS Visual Studio project & solution files.
+
+#Supported Visual Studio versions
+
+Currently supported versions are Visual Studio 2013 (our primary focus) and 2010.
+
+#Building
+We are using [NuGet](http://www.nuget.org) to pull zlib and openssl dependencies.
+If you don't have Visual Studio NuGet plugin installed, you'll need to
+download nuget.exe from the web and manually restore the NuGet packages.
+
+```
+> REM Run from this directory.
+> REM No need to do this if you have NuGet visual studio extension.
+> nuget restore
+```
+
+After that, you can build the solution using one of these options:
+1. open `grpc.sln` with Visual Studio and hit "Build".
+2. build from commandline using `msbuild grpc.sln /p:Configuration=Debug`
+
+#Testing
+
+Use `run_tests.py`, that also supports Windows (with a bit limited experience).
+```
+> REM Run from repository root.
+> python tools\run_tests\run_tests.py -l c
+```
+
+Also, you can `make.bat` directly to build and run gRPC tests.
+```
+> REM Run from this directory.
+> make.bat alarm_test
+```
