What version of Swashbuckle.AspNetCore 5.0.0 are you using? A minimum of rc2 is required for use with .NET Core 3.0, see #1061.

[CmdrBeavis]

I'm getting a fairly similar, but different set of exceptions. Can I assume that I should open a different issue? (And I've installed 5.0.0-rc4 into this tutorial project.)
( Tutorial is at: https://docs.microsoft.com/en-us/visualstudio/get-started/csharp/tutorial-aspnet-core-ef-step-04?view=vs-2019 )

Thanks.

I am having the same issue, running .net core 3. everything is the latest version.

[Elvin1492]

Hi, we still have the same exception with swashbuckle
Is there any updates?

Lifetime: Transient ImplementationType: Swashbuckle.AspNetCore.SwaggerGen.SchemaRegistryFactory': Failed to compare two elements in the array.use it is an interface

[ghost]

Same troubles on ASP Net Core 3. Everything is latest.

To reproduce it's enough to add swagger in ConfigureServices:

        public void ConfigureServices(IServiceCollection services)
        {
            services.AddControllers();
            services.AddSwaggerGen();
        }

.csproj file:

<Project Sdk="Microsoft.NET.Sdk.Web">

    <PropertyGroup>
        <TargetFramework>netcoreapp3.0</TargetFramework>
    </PropertyGroup>

    <ItemGroup>
      <PackageReference Include="Microsoft.OpenApi" Version="1.1.4" />
      <PackageReference Include="Swashbuckle.AspNetCore" Version="4.0.1" />
      <PackageReference Include="Swashbuckle.AspNetCore.Swagger" Version="4.0.1" />
      <PackageReference Include="Swashbuckle.AspNetCore.SwaggerGen" Version="4.0.1" />
      <PackageReference Include="Swashbuckle.AspNetCore.SwaggerUi" Version="4.0.1" />
    </ItemGroup>

</Project>

same here

[martincostello]

What version of Swashbuckle.AspNetCore 5.0.0 are you using? A minimum of rc2 is required for use with .NET Core 3.0, see #1061.

You must use at least 5.0.0-rc2 for ASP.NET Core 3.0. Prior versions do not work with ASP.NET Core 3.0.

[nizmow]

Strangely, I ran into a very similar problem while setting up an ASP.NET Core 3 application. In my case I was using 5.0.0-rc4. Turned out I hadn't yet added a controller of any kind to the application, as I was creating a skeleton app from scratch. Added a controller with a dummy controller action and the problem went away.

[Brubning]

I had the same problem on ASP.NET Core 3.0 with Swagger 4.0.0, which as mentioned isn't supported (despite the documents saying ASP.NET Core version >= 2.0 for Swagger v4.0).

I upgraded to 5.0.0-rc4 (which requires Microsoft.OpenAPi 1.1.4), and then verified that all controllers and methods were decorated with routing attributes and that all non-route parameters where decorated with FromBody or FromQuery.

Now working fine.

[carlblanchard]

Brubning thanks for the pointer... working great now.
I have to change the signature to
services.AddSwaggerGen(c => { c.SwaggerDoc("v1", new Microsoft.OpenApi.Models.OpenApiInfo { Title = "Put title here", Description = "DotNet Core Api 3 - with swagger" }); });

[kkmeteor]

I had the same problem on ASP.NET Core 3.0 with Swagger 4.0.0
Then I use the Swashbuckle.AspNetCore versioned 5.0.0-rc5 to solve this issue.
