Я пытаюсь интегрировать Swagger в проект ASP NET Core 3.0
, и он выдает исключение прямо в методе ConfigureServices
:
Я использую Swashbuckle.AspNetCore
4.0.1.
Iтакже проверил этот выпуск , а также этот
public void ConfigureServices(IServiceCollection services)
{
services.AddSwaggerGen(c =>
{
c.SwaggerDoc("v1", new Swashbuckle.AspNetCore.Swagger.Info
{
Version = "v1",
Title = " API",
Description="API for the Server",
});
});
}
Исключение
System.AggregateException

PS Я следовал этому руководству , и единственное отличие состоит в том, что, хотя он использует объект OpenApiInfo
, у меня нет этой перегрузки, и поэтому я использую Info
.
