+# 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:

+# 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.CSharpNetCoreClientCodegen
+
+<a name="frameworks-supported"></a>
+## Frameworks supported
+- .NET Core >=1.0
+- .NET Framework >=4.6
+- Mono/Xamarin >=vNext
+
+<a name="dependencies"></a>
+## Dependencies
+
+- [RestSharp](https://www.nuget.org/packages/RestSharp) - 106.11.7 or later
+- [Json.NET](https://www.nuget.org/packages/Newtonsoft.Json/) - 12.0.3 or later
+- [JsonSubTypes](https://www.nuget.org/packages/JsonSubTypes/) - 1.8.0 or later
+- [CompareNETObjects](https://www.nuget.org/packages/CompareNETObjects) - 4.61.0 or later
+- [System.ComponentModel.Annotations](https://www.nuget.org/packages/System.ComponentModel.Annotations) - 5.0.0 or later
+
+The DLLs included in the package may not be the latest version. We recommend using [NuGet](https://docs.nuget.org/consume/installing-nuget) to obtain the latest version of the packages:
+```
+Install-Package RestSharp
+Install-Package Newtonsoft.Json
+Install-Package JsonSubTypes
+Install-Package System.ComponentModel.Annotations
+Install-Package CompareNETObjects
+```
+
+NOTE: RestSharp versions greater than 105.1.0 have a bug which causes file uploads to fail. See [RestSharp#742](https://github.com/restsharp/RestSharp/issues/742).
+NOTE: RestSharp for .Net Core creates a new socket for each api call, which can lead to a socket exhaustion problem. See [RestSharp#1406](https://github.com/restsharp/RestSharp/issues/1406).
+
+<a name="installation"></a>
+## Installation
+Generate the DLL using your preferred tool (e.g. `dotnet build`)
+
+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;
+```
+<a name="usage"></a>
+## Usage
+
+To use the API client with a HTTP proxy, setup a `System.Net.WebProxy`
+```csharp
+Configuration c = new Configuration();
+System.Net.WebProxy webProxy = new System.Net.WebProxy("http://myProxyUrl:80/");
+webProxy.Credentials = System.Net.CredentialCache.DefaultCredentials;
+c.Proxy = webProxy;
+```

+using System.Diagnostics;
+using Org.OpenAPITools.Api;
