Azure precompiled feature and CloudTable binding output not working

Question

I am using a precompiled Azure Function that looks like:

public static async Task Run(Stream inputBlob, Stream outputJson, Stream outputXml, CloudTable schedulerTable)

The printout is as follows:

{
  "name": "schedulerTable",
  "type": "table",
  "direction": "out",
  "tableName": "SchedulerTable",
  "connection": "SchedulerTable"
}

When I remove the schedulerTable parameter from my function, it works. "The message that the host throws in my face:

Microsoft.Azure.WebJobs.Host: Error indexing method 'Functions.InputFileAdaptorAF'. Microsoft.Azure.WebJobs.Host: Can't bind Table to type 'Microsoft.WindowsAzure.Storage.Table.CloudTable'.

Indeed, when I add a table output binding trying to use different alternatives, nothing works. Alternatives that do not work:

• The schedulerTable parameter with the type SchedulerRegister. The SchedulerRegister class inherits from TableEntity.
• The schedulerTable parameter with type ICollector.
• The schedulerTable parameter with type CloudTable. (higher).

Please ¿How can I fix this? (Use output binding to azure table)
