How to run azure function locally with HTTPS from visual studio 2022

I am trying to run azure functions locally with HTTPS from visual studio 2022 but haven't managed to get it working.

No messages on startup related to HTTPS so I don't know if it is trying but failing or simply not even trying HTTPS.

New win 11 build & install of VS 2022 as of a few days ago - I can test fine against HTTP locally and run against HTTPS when deployed to Azure.

Have tried using local.settings.json with a couple of variations of settings that have been suggested from searches ..

Have tried putting suggested 'host' commands in the debug command line section ..

Have created a self signed cert that is in the local machine store and referenced that.

Have created a .pfx file in solution directory and referenced that.

Project properties are:

<Project Sdk="Microsoft.NET.Sdk">
  <PropertyGroup>
    <TargetFramework>net6.0</TargetFramework>
    <AzureFunctionsVersion>v4</AzureFunctionsVersion>
  </PropertyGroup>
  <ItemGroup>
    <PackageReference Include="Microsoft.Data.SqlClient" Version="3.0.0" />
    <PackageReference Include="Microsoft.NET.Sdk.Functions" Version="4.1.1" />
  </ItemGroup>
  <ItemGroup>
    <None Update="host.json">
      <CopyToOutputDirectory>PreserveNewest</CopyToOutputDirectory>
    </None>
      <CopyToOutputDirectory>PreserveNewest</CopyToOutputDirectory>
      <CopyToPublishDirectory>Never</CopyToPublishDirectory>
    </None>
    <None Update="launchSettings.json">
      <CopyToOutputDirectory>PreserveNewest</CopyToOutputDirectory>
      <CopyToPublishDirectory>Never</CopyToPublishDirectory>
    </None>
    <None Update="local.settings.json">
      <CopyToOutputDirectory>PreserveNewest</CopyToOutputDirectory>
      <CopyToPublishDirectory>Never</CopyToPublishDirectory>
    </None>
  </ItemGroup>
</Project>

    Hello @Paul Franklin - Thanks for reaching out. Running Functions locally under HTTPS requires additional configuration. You'll need to create a certificate locally and configure Visual Studio to use it when starting the host process. Could you try out the steps in the following blog post and see if it helps?
