After Upgrading to swagger version 6.4.0 , we are getting error:
Method not found: 'Microsoft.OpenApi. Models.OpenApiSchema Swashbuckle. AspNetCore.SwaggerGen. IschemaGenerator.GenerateSchema

@domaindrivendev Please suggest a workaround. We need to fix this as soon as possible. Unable to upgrade to any swagger version after 5.5

Steps to replicate the issue:

1. Upgraded the swagger version in 2 files:
   1.1. dotnet-tools.json file inside .config folder of our project : {"version":1,"isRoot":true,"tools":{"swashbuckle.aspnetcore.cli":{"version":"6.2.3","commands":["swagger"]}}}
   1.2. Package.props file :
2. ran commad :
   dotnet swagger tofile --output destination-folder/swagger.json --serializeasv2 dll-file 1.0

This seems to work #2369 (comment)

This issue is stale because it has been open for 60 days with no activity. It will be automatically closed in 14 days if no further updates are made.

#2801 would guard against unintended breaking changes in the future.
