Bueno, estaba haciendo un proyecto DDD, específicamente usando redis, pero no creo que tenga nada que ver.

El problema es que no me aparece el swagger, falla, pero cuando hago pedidos en cartero funciona normalmente.

Ese es el error:

 Microsoft.AspNetCore.Diagnostics.DeveloperExceptionPageMiddleware[1] An unhandled exception has occurred while executing the request. System.TypeLoadException: Could not load type 'Microsoft.AspNetCore.Http.Metadata.ITagsMetadata' from assembly 'Microsoft.AspNetCore.Http.Abstractions, Version=6.0.0.0, Culture=neutral, PublicKeyToken=adb9793829ddae60'. at Swashbuckle.AspNetCore.SwaggerGen.SwaggerGeneratorOptions.DefaultTagsSelector(ApiDescription apiDescription) at Swashbuckle.AspNetCore.SwaggerGen.SwaggerGeneratorOptions.DefaultSortKeySelector(ApiDescription apiDescription) in Swashbuckle.AspNetCore.SwaggerGen.dll:token 0x600012d+0x0 at System.Linq.EnumerableSorter`2.ComputeKeys(TElement[] elements, Int32 count) in System.Linq.dll:token 0x600040b+0x10 at System.Linq.EnumerableSorter`1.ComputeMap(TElement[] elements, Int32 count) in System.Linq.dll:token 0x6000401+0x0 at System.Linq.EnumerableSorter`1.Sort(TElement[] elements, Int32 count) in System.Linq.dll:token 0x6000402+0x0 at System.Linq.OrderedEnumerable`1.GetEnumerator()+MoveNext() in System.Linq.dll:token 0x6000391+0x3d at System.Linq.Lookup`2.Create(IEnumerable`1 source, Func`2 keySelector, IEqualityComparer`1 comparer) in System.Linq.dll:token 0x6000366+0x2b at System.Linq.GroupedEnumerable`2.GetEnumerator() in System.Linq.dll:token 0x600035f+0x0 at Swashbuckle.AspNetCore.SwaggerGen.SwaggerGenerator.GeneratePaths(IEnumerable`1 apiDescriptions, SchemaRepository schemaRepository) in Swashbuckle.AspNetCore.SwaggerGen.dll:token 0x60000f8+0x3a at Swashbuckle.AspNetCore.SwaggerGen.SwaggerGenerator.GetSwagger(String documentName, String host, String basePath) in Swashbuckle.AspNetCore.SwaggerGen.dll:token 0x60000f6+0xe6 at Swashbuckle.AspNetCore.Swagger.SwaggerMiddleware.Invoke(HttpContext httpContext, ISwaggerProvider swaggerProvider) in Swashbuckle.AspNetCore.Swagger.dll:token 0x6000009+0xe2 at Microsoft.AspNetCore.Diagnostics.DeveloperExceptionPageMiddleware.Invoke(HttpContext context) in Microsoft.AspNetCore.Diagnostics.dll:token 0x60000aa+0x82

Archivo de inicio ( ConfigureServices ):

 public void ConfigureServices(IServiceCollection services) { services.AddRedisContext(Configuration); services.AddControllers(); services.AddSwaggerGen(c => { c.SwaggerDoc("v1", new OpenApiInfo { Title = "Basket.Api", Version = "v1" }); });

Mi método en la clase de método de extensión:

 public static IServiceCollection AddRedisContext(this IServiceCollection services, IConfiguration config) { services.AddStackExchangeRedisCache(options => { options.Configuration = config["CacheSettings:ConnectionString"]; }); services.AddScoped<IBasketRepository, BasketRepository>(); services.AddScoped<IBasketService, BasketService>(); return services; }

La referencia del paquete:

 <Project Sdk="Microsoft.NET.Sdk.Web"> <PropertyGroup> <TargetFramework>net6.0</TargetFramework> </PropertyGroup> <ItemGroup> <PackageReference Include="Swashbuckle.AspNetCore" Version="6.2.3" /> </ItemGroup> <ItemGroup> <ProjectReference Include="..\Basket.Infra.Data\Basket.Infra.Data.csproj" /> </ItemGroup> </Project>

También comenté las líneas que se refieren a redis y todavía daba el mismo error. Así que es casi seguro que es algo relacionado con la arrogancia.
