I\'m using a precompiled Azure Function that looks:
public static async Task Run(Stream inputBlob, Stream outputJson, Stream outputXml, CloudTable schedulerT
Really, this answer is from someone (i don't remember de name) in the team of Azure Functions, here in this question, but he delete her response. He says that surely the problem is from having diferent version of the dll that expected. I can confirm that these was the problem.
The solution is to check the version of dlls used in AppData\Local\Azure.Functions.Cli\1.0.0-beta.91 and use the same in the solution.
