Description

Hello,

I am trying to generate a client for the GitHub OpenAPI Documentation

I am using the aspnetcore generator. Unfortunately, a lot of InlineResponse and InlineObject models are created with syntax errors.

openapi-generator version

I am using the latest master but have also tried out the v5.0.0-beta2.

OpenAPI declaration file content or url

GitHub OpenAPI Documentation

Generation Details and steps to reproduce

I am doing the following steps to generate the client.

runner.sh

#!/bin/bash

docker run --rm -v "${PWD}:/local" openapitools/openapi-generator-cli:v5.0.0-beta2 validate \
    -i https://raw.githubusercontent.com/github/rest-api-description/main/descriptions/api.github.com/api.github.com.json


docker run --rm -v "${PWD}:/local" openapitools/openapi-generator-cli:v5.0.0-beta2 generate \
    -i https://raw.githubusercontent.com/github/rest-api-description/main/descriptions/api.github.com/api.github.com.json \
    -g aspnetcore \
    -c /local/config.yaml \
    -o /local/out/aspnetcore

config.yaml

aspnetCoreVersion: 3.1
buildTarget: library
compatibilityVersion: Version_3_1
isLibrary: true
operationIsAsync: true
operationResultTask: true
packageName: Library.Github
packageTitle: Github Api Client
useDateTimeOffset: true
useNewtonsoft: true
useSwashbuckle: true

When observing the result and trying to build it I get the following:

I then had a look at some of the InlineObjcet classes and some syntax errors there:

/// <summary>
        /// Exclude attributes from the API response to improve performance
        /// </summary>
        /// <value>Exclude attributes from the API response to improve performance</value>
        [TypeConverter(typeof(CustomEnumConverter<List&lt;ExcludeEnum&gt;>))]
        [JsonConverter(typeof(Newtonsoft.Json.Converters.StringEnumConverter))]
        public enum List&lt;ExcludeEnum&gt;
        {
            
            /// <summary>
            /// Enum RepositoriesEnum for repositories
            /// </summary>
            [EnumMember(Value = "repositories")]
            RepositoriesEnum = 1
        }

furthermore, the one of and any of does not seem to be generated properly..
