System.InvalidOperationException for XmlCommentsParameterFilter

[sgoldberg16]

I am having the following exception throw after upgrading to .Net8: System.InvalidOperationException: A suitable constructor for type 'Swashbuckle.AspNetCore.SwaggerGen.XmlCommentsParameterFilter' could not be located. Ensure the type is concrete and all parameters of a public constructor are either registered as services or passed as arguments. Also ensure no extraneous arguments are provided.

Any initial thoughts or suggested fixes would be appreciated! Using Swashbuckle.AspNetCore 6.5.0 Using Swashbuckle.AspNetCore.SwaggerUI 6.5.0 Using Swashbuckle.AspNetCore.SwaggerGen 6.5.0 Using Swashbuckle.AspNetCore.Swagger 6.5.0

Have you tested with https://github.com/Havunen/DotSwashbuckle https://www.nuget.org/packages/DotSwashbuckle.AspNetCore

It's not obvious to me at first glance why this wouldn't be working.

The activation call comes from here:

https://github.com/domaindrivendev/Swashbuckle.AspNetCore/blob/830c5a6f7468bce6b716d84c034a258dbbcbfe98/src/Swashbuckle.AspNetCore.SwaggerGen/DependencyInjection/ConfigureSwaggerGeneratorOptions.cs#L76-L77

The constructor receives a single XPathDocument:

https://github.com/domaindrivendev/Swashbuckle.AspNetCore/blob/830c5a6f7468bce6b716d84c034a258dbbcbfe98/src/Swashbuckle.AspNetCore.SwaggerGen/XmlComments/XmlCommentsParameterFilter.cs#L11

Which is provided as the argument here:

https://github.com/domaindrivendev/Swashbuckle.AspNetCore/blob/830c5a6f7468bce6b716d84c034a258dbbcbfe98/src/Swashbuckle.AspNetCore.SwaggerGen/DependencyInjection/SwaggerGenOptionsExtensions.cs#L433

It might be related to this breaking change in .NET 8.

Having updated Swashbuckle to target net8.0, I can't replicate this with our test suite.

Please provide a minimal reproducible example as a GitHub repository that demonstrates the issue you're experiencing so we can look into this further.
