Generated XML Documentation File Not Working

[yatteer]

Anyone else having issues with XML Documentation? The feature seems not to be working.
Azure Functions unable to locate XML file...

{
"version": "2.0",
"extensions": {
"Swashbuckle": {
"XmlPath": "Func.xml"
}
}
}

In Azure functions v3, Its read from the current IConfiguration instance in the DI provider, not from host.json.
If you put it in this path in your config, it will be read:
"AzureWebJobs": {
"extensions": {
"Swashbuckle": {
"XmlPath": "your.api.xml.file.name.without.path.xml"
}
}
}
