The generator script `./openapi/csharp.sh` doesn't work

[Xulei-NL]

I used bash ./openapi/csharp.sh OUTPUT_CSHARP ./setting to generate C# code but only two swagger files were generated. See the structure below:

tree OUTPUT_CSHARP
OUTPUT_CSHARP
├── swagger.json
└── swagger.json.unprocessed

However Java code can be generated with bash ./openapi/java.sh OUTPUT_JAVA ./setting. In addition, Python code can also be generated.

tree OUTPUT_JAVA
OUTPUT_JAVA
├── api
│   └── openapi.yaml
├── build.gradle
├── build.sbt
├── docs
│   ├── AdmissionregistrationApi.md
│   ├── AdmissionregistrationV1alpha1Api.md
│   ├── AdmissionregistrationV1Api.md
│   ├── AdmissionregistrationV1beta1Api.md
...

The setting file contains:

KUBERNETES_BRANCH=master
CLIENT_VERSION=1.4.0
PACKAGE_NAME=client

The CSharp code generation is part of the build. If you just run dotnet build in that root directory it should work.

We should possibly update the script to print this information since it is different than the other generators.
