Problem with OnBeforeGeneration

[wreuel]

I have the following MyGenarationSpec:

using My.Project.Common.Data;
using My.Project.Domain.Dto;
using My.Project.ExternalServices.Data.Profiles.Base;
using My.Project.Services.Tracker;
using System.Reflection;
using TypeGen.Core.Converters;
using TypeGen.Core.SpecGeneration;

namespace My.Project.Specs
{
    public class MyGenerationSpec : GenerationSpec
    {
        public override void OnBeforeGeneration(OnBeforeGenerationArgs args)
        {
            args.GeneratorOptions.BaseOutputDirectory = "../myProject/src/models/";
            args.GeneratorOptions.FileNameConverters = new TypeNameConverterCollection(new PascalCaseFileNameConverter());
            args.GeneratorOptions.FileHeading = "";
            args.GeneratorOptions.PropertyNameConverters = new MemberNameConverterCollection(new PascalCaseToCamelCaseConverter());

            AddInterface(typeof(ResponseDto), "Common");
            AddInterface(typeof(ResponseGenericDto<>), "Common");
            AddInterface(typeof(StationGroup), "Data");
            AddInterface(typeof(StationClient), "Data");

            Assembly[] currentAssemblies = AppDomain.CurrentDomain.GetAssemblies()
                    .Where(d => !string.IsNullOrEmpty(d.FullName) && d.FullName.Contains("My.Project", StringComparison.OrdinalIgnoreCase)).ToArray();

            var enumTypes = currentAssemblies
              .SelectMany(x => x.GetTypes()
                                  .Where(t => !string.IsNullOrEmpty(t.FullName)
                                              && t.FullName.Contains("My.Project")
                                              && t.IsEnum)
                          )
              .Distinct()
              .ToList();

            foreach (var item in enumTypes)
            {
                AddEnum(item, "Enums");
            }


            Assembly[] domainAssemblies = (from x in currentAssemblies
                                           where x.GetTypes().Contains(typeof(OrderDto))
                                           select x).ToArray();

            var domainDto = domainAssemblies
               .SelectMany(x => x
                   .GetTypes()
                   .Where(d => d.Name.EndsWith("DTO", StringComparison.OrdinalIgnoreCase)
                           && !d.Name.Equals("ResponseDto")))
               .Distinct()
               .ToList();

            foreach (var item in domainDto)
            {
                AddInterface(item, "Dto");
            }

            var dtosApplicationData = currentAssemblies
             .SelectMany(x => x
                 .GetTypes()
                 .Where(d => d.Name.EndsWith("Dto", StringComparison.OrdinalIgnoreCase)
                            ))

             .Distinct()
            .ToList();

            foreach (var dto in dtosApplicationData)
            {
                AddInterface(dto, "Dto");
            }

            var responses = currentAssemblies
             .SelectMany(x => x
                 .GetTypes()
                 .Where(d => (d.Name.EndsWith("Response", StringComparison.OrdinalIgnoreCase)))
             .Distinct()
             .ToList();

            var configs = currentAssemblies
              .SelectMany(x => x
                  .GetTypes()
                  .Where(d =>
                  (d.Name.EndsWith("Configurations")
                  || d.Name.EndsWith("WebServiceConfig"))
                  && !d.Name.Equals("ReloadConfigurationsCommand", StringComparison.OrdinalIgnoreCase)))
              .Distinct()
              .ToList();

            responses.AddRange(configs);

            foreach (var response in responses)
            {
                AddInterface(response, "Response");
            }

            var requests = currentAssemblies
             .SelectMany(x => x
                 .GetTypes()
                 .Where(d => d.Name.EndsWith("Request", StringComparison.OrdinalIgnoreCase)))
             .Distinct()
            .ToList();

            foreach (var request in requests)
            {
                AddInterface(request, "Request");
            }
        }
    }
}

And when I do the build or rebuild, knowing that I have the following command to ben run on the .csproj

<Target Name="PostBuild" AfterTargets="PostBuildEvent" Condition="'$(Configuration)' == 'Debug'">
	<Exec Command="dotnet-typegen generate" ContinueOnError="true" IgnoreExitCode="true" />
</Target>

I'm getting the following error:

But the ts files are generate correctly. What is that? How can I fix any ideias?

This could happen when TypeGen CLI's .NET version is older than the project's .NET version. Which TypeGen version are you using? It looks like the CLI doesn't have the string.Contains(string, StringComparison) overload, but this overload is quite old (it was introduced in .NET Core 2.1), so newer versions of TypeGen should be able to call it.
