[C#] Fix issue OpenAPITools#1088 with generation of enum classes refe…

…renced from other objects (OpenAPITools#1089)

* Run ./bin/utils/ensure-up-to-date to re-generate samples run in the CI.

* Fixed the OpenAPITools#1088 issue by removing the update of enumeration properties while processing objects that reference them. Launched the ./bin/csharp-petstore-all.sh script.

+# OpenAPI Generator Ignore
+# Generated by openapi-generator https://github.com/openapitools/openapi-generator
+
+# Use this file to prevent files from being overwritten by the generator.
+# The patterns follow closely to .gitignore or .dockerignore.
+
+# As an example, the C# client generator defines ApiClient.cs.
+# You can make changes and tell OpenAPI Generator to ignore just this file by uncommenting the following line:
+#ApiClient.cs
+
+# You can match any string of characters against a directory, file or extension with a single asterisk (*):
+#foo/*/qux
+# The above matches foo/bar/qux and foo/baz/qux, but not foo/bar/baz/qux
+
+# You can recursively match patterns against a directory, file or extension with a double asterisk (**):
+#foo/**/qux
+# This matches foo/bar/qux, foo/baz/qux, and foo/bar/baz/qux
+
+# You can also negate patterns with an exclamation (!).
+# For example, you can ignore all files in a docs folder with the file extension .md:
+#docs/*.md
+# Then explicitly reverse the ignore rule for a single file:
+#!docs/README.md

+# Org.OpenAPITools - the C# library for the OpenAPI Petstore
+
+This is a sample server Petstore server. For this sample, you can use the api key `special-key` to test the authorization filters.
+
+This C# SDK is automatically generated by the [OpenAPI Generator](https://openapi-generator.tech) project:
+
+- API version: 1.0.0
+- SDK version: 1.0.0
+- Build package: org.openapitools.codegen.languages.CSharpDotNet2ClientCodegen

+## Frameworks supported
+- .NET 2.0
+
+<a name="dependencies"></a>
+## Dependencies
+- Mono compiler
+- Newtonsoft.Json.7.0.1
+- RestSharp.Net2.1.1.11
+
+Note: NuGet is downloaded by the mono compilation script and packages are installed with it. No dependency DLLs are bundled with this generator
+
+<a name="installation"></a>
+## Installation
+Run the following command to generate the DLL
+- [Mac/Linux] `/bin/sh compile-mono.sh`
+- [Windows] TODO
+
+Then include the DLL (under the `bin` folder) in the C# project, and use the namespaces:
+```csharp
+using Org.OpenAPITools.Api;
+using Org.OpenAPITools.Client;
+using Org.OpenAPITools.Model;
+```
