Swagger allows setting the parameter type but with SwaggerWcf I can't edit this file, it's generated. It's set to body by default, but I need it to be path.
One might think SwaggerWcfParameterAttribute would allow setting this. But it only allows Description and Required.
How can it be set specifically?
Did you try using the format in the sample service?

The parameter id from the path will be passed to the function
