Azure function build not generating function.json

Question

I have an azure function that was working perfectly this morning (was published on Azure). I had to add some logging functionality in Azure Storage and suddently I cannot run my function anymore. I have not tried to publish it as it does not run locally.

The symptom is that I get the following exception:

System.IO.FileNotFoundException: 'Could not find file 'C:\projects\MySuperFunction\MySuperFunction\bin\Debug\netstandard2.0\bin\function.json'.'

I read that thtis file is supposed to be generated at build time but I can confirm that the file is not there at all.

The only modifications I made to the project was to add a reference to the WindowsAzure.Storage nuget package (v9.2.0)

Does anyone knows why it is failing now while it was not before and, ideally, how to get it back working?

Answer 1

For my situation at least this wasn't an irrecoverable exception and simply continuing with the debug session worked fine.

I turned off 'Break on Exception' for FileNotFoundException and it was all good :)

(I didn't have the WindowsAzure.Storage change in my project, so YMMV)
