VS2022无法创建Azure函数项目

Question

If I try to create an Azure Functions Project (Solution->Add->New Project) I get a new project folder that is completely empty, and a status message in the statusbar that says the project was created successfully.

I've already done a VS Update to 17.1.1 which didn't change anything, then did a complete repair of VS2022 from the VSInstaller. I also reinsalled the Azure Functions Core Tools v4 with npm i -g azure-functions-core-tools@4 --unsafe-perm true .

I've tried creating both a net6 and net6 isolated function (timer trigger), but only the empty folder is ever created with no errors shown.

I suppose my alternative at this point is to just manually create/copy a project file and try to go from there.

Note:

1. Re-install the .NET 6 SDK and the Runtime Package

2. Restart the System and try creating the new Azure Functions Project from Visual Studio 2022 Professional.

Updated Answer:

Go to Visual Studio Professional 2022 > Tools > Select Get Tools and Features

Uninstall the Azure Development feature from that Catalogue and Re-install it, as shown below:

Answer 2

I had the same issue using Visual Studio 2022 Professional. I wasn't able to create an Azure Function v4 (.NET 6) and tried the following workarounds from the previous answers without success:

• Reinstalled the Azure Functions Core Tools v4
• Reinstalled .NET SDK and Azure SDK
• Several computer and Visual Studio restarts

After several actions I was able to make it works again but I don't know which action was important.

I listed below all significant actions in the order I did them. Maybe that will help someone fixing this annoying issue !

Check Azure credentials status

I checked that my Azure Credentials were still valid. They weren't, I had to refresh them.
In Visual Studio, go to Help > Register Visual Studio dialog, you will see if it's ok.

Screenshot was taken after credential refresh:

Run a function created by a colleague

Since I wasn't able to create a new Azure Function inside VS 2022 Pro, I asked a colleague to create one for me to see if I was able to run it locally.

I was able to run the function my colleague created (debug in VS 2022)

Try Visual Studio 2019

I still have Visual Studio 2019 installed and I had the idea to try creating a Function here.

I was able to create a new Azure Function in an empty solution using Visual Studio 2019

Try again using Visual Studio 2022

It worked in VS 2019, it's time to try again in Visual Studio 2022.

I was finally able to create an Azure Function project in VS 2022

As I said earlier, I don't know which action unblocked the issue. Hope it can help someone else struggling with this issue.

Answer 3

I finally ended up deleting the following folder:

C:\Users\YOURUSER\AppData\Local\AzureFunctionsTools

Visual Studio uses the files in the folder to get the last version of Azure Functions Tools. If you remove the folder, once you open Visual Studio again, it regenerates that folder and then your Visual Studio is able to get the Azure Function workers
