Visual Studio 2017/2019 fails when I create an Azure Functions project

I encounter the issue that I can’t create an Azure Functions project.

We can create other project. However not for Azure Functions. If I try to create an Azure Functions project on VS2017, it says, One or more errors occurred.

For VS2019, it says, Illegal characters in path.

I remove/re-install the VS however, it is the same.

Solution

Remove %localappdata%\AzureFunctionsTools . It solves both cases. I encountered this solution before, at that time it was different error. Next time, I should try this work around. If we remove the directory, maybe the tools folder was broken.

Project creation failed - Azure functions - Developer Community
