IIS Local Dev, connectionStrings with AKV

[coryisakson]

I am getting the following error when using the AKV Builder and running a project on local IIS. The error does not occur with IIS Express. It also does not occur with appSettings, it is only with connecitonStrings.
To reproduce the error:
Launch VS 2019 as Admin
Created a new ASP.NET MVC project.
Changed the target framework to .NET 4.7.2.
Added the package for Microsoft.Configuration.ConfigurationBuilders.Azure v.2.0.0
Change the deploy target to Local IIS
Added the configBuilders="AzureKeyVault" attribute to the connectionStrings.

Following the instructions here: MicrosoftDocs/azure-docs#17023 (comment) I am able to access the Key Vault even though the error still appears when starting the site via VS. Is it possible to prevent this error?
