I'm working on a project to build a website and add azure function that will have a counter of how many people have visited the site. I am stuck at this point https://youtu.be/ieYrBWmkfno?t=1879. This is where I'm getting my error. I found a similar post here NU1100:Unable to resolve 'Microsoft.NET.Sdk.Functions (>= 3.0.3)' for '.NETCoreApp,Version=v3.1' . I will be honest I don't know enough about what I'm doing to even troubleshoot it. I'm using vscode and git bash as a terminal. I tried:

1. Resolving the dependencies
2. Downloading and installing the .net 6.0 sdk and runtime
   • Originally I tried this with .net version 6 when I was creating the azure function but the video used 3.0 lts so I changed it 3.1
3. Downloading and installing the nuget

Any help would be appreciated. This is also my first post here so I did my best to follow the question guidelines
