Azure-webjobs-sdk: [Visual Studio] Unable to start debugging or run Function code using VS Tooling (console crashes)

[SimonLuckenuik]

Unable to start debugging using Visual Studio Tooling for Azure Functions Preview.

Repro steps

Start debugging my newly created Function project in Visual Studio.
Command line arguments of the command prompt started by VS2015: C:\Users\dev\AppData\Local\Azure.Functions.Cli\1.0.0-beta.8\func.exe host start --port 7071 & pause

Expected behavior

Starting project and debugger attaches to my function.

Actual behavior

Console crashes, call stack:

@SimonLuckenuik thank you for all the information provided. One quick question. If you don't mind, could you share your machine name (the local machine/host name)? If you don't want to disclose that information, can you verify if it conflicts with the Host ID requirements specified in the exception?

@lindydonna FYI. This may need to be moved to the https://github.com/Azure/Azure-Functions repo.

[SimonLuckenuik]

@fabiocav machine name: SPECTRE-LAPTOP (as returned by the hostname command line)
So it doesn't respect the rule, since it has capital letters only.

[lindydonna]

@fabiocav This issue technically belongs in https://github.com/Azure/azure-webjobs-sdk-script.

@SimonLuckenuik I think the issue is more likely to be the folder name (which is used to generate the host ID on the command line). Could you provide the foldername where you're launching the CLI?

We have these open issues that are related:
https://github.com/Azure/azure-webjobs-sdk-script/issues/1007
https://github.com/Azure/azure-webjobs-sdk-script/issues/1006

[lindydonna]

Btw @SimonLuckenuik did you find guidance somewhere that said to file tooling issues here? We have a lot of readmes in various places, so I want to make sure I track down the right place. :)

[SimonLuckenuik]

@lindydonna The Azure Function project I used to start the CLI Path is located here: C:\git\RemovedApi\Removed.Api.Web\

The issue location was from a post on Yammer (Donna Malayeri). I was initially planning on submitting in Azure-Functions (why I have the VS tag in the title), but when I realized while investigating that it was CLI related based on the callstack and cmd line args, I created it here, but forgot to change "Visual Studio" to "CLI" :)

[MisinformedDNA]

I just filed azure/azure-webjobs-sdk-script#1021 and then found this issue. I also found that if I create the project with no spaces, then it works fine.

[lindydonna]

@SimonLuckenuik Can you confirm that the the issue is resolved if you remove periods from your project name? If so, please close as this is already tracked by Azure/azure-webjobs-sdk-script#1007 and Azure/azure-webjobs-sdk-script#1006

[SimonLuckenuik]

@lindydonna The dots in the project name have no effect. I kept the dots in the filename, but removed the dots from the folder name in which the project was and it started working in order to have it working.

[lindydonna]

Awesome, thanks @SimonLuckenuik. Can I close this issue as a duplicate since we have the "dot folder name" issue tracked?

[SimonLuckenuik]

Sure you can close it, thank you for your support.

[lindydonna]

Closing as duplicate of https://github.com/Azure/azure-webjobs-sdk-script/issues/1006

[fabiocav]

@lindydonna I mentioned the meta repo because those are the instructions on the blog post (https://blogs.msdn.microsoft.com/webdev/2016/12/01/visual-studio-tools-for-azure-functions/) so you may need to update the forward link (https://go.microsoft.com/fwlink/?linkid=836326), otherwise we'll see them opened in the meta repo instead.

[SimonLuckenuik]

Maybe one general comment, for end-users who are just getting started, it may not be obvious what goes where, it would probably be easier to have everything reported in a central location which is clearly tagged as 'Azure Functions' (eg https://github.com/Azure/Azure-Functions) and move it to the proper repository after. While people may understand that Azure Function leverage WebJobs, it might not be obvious to know which part of the product is affected by a bug/problem. I would not expect people to start looking in multiple repositories to know if the issue they have is already raised or not.

[MisinformedDNA]

I think they should be centralized under one name. We don't need WebJobs and Functions. They are practically the same.
