AWS Lambda Function and Microsoft.Data.SqlClient and Mock Lambda Tool

Visual Studio Version 16.6.4
DotNet version 3.1.302

Step 1: Create a Lambda function empty.
Step 2: Debug using the Mock lambda tool. All is well.
Step 3: Add nuget package Microsoft.Data.SqlClient (no code was added)
Step 4: Debugging produces:

AWS .NET Core 3.1 Mock Lambda Test Tool (0.10.0)
Unknown error occurred causing process exit: Dependency resolution failed for component C:\Dev\SourceControl\Development\Test\AWSLambda1\bin\Debug\netcoreapp3.1\AWSLambda1.dll with error code -2147450740. Detailed error: Error:

Reproduce the issue with the AWS .NET Core 3.1 Mock Lambda Test Tool after adding Microsoft.Data.SqlClient to an otherwise empty Lambda function. Start by reading LambdaAssemblyLoadContext.cs and LocalLambdaRuntime.cs at the stack-trace locations, then inspect AWSLambda1.deps.json and the missing Microsoft.Data.SqlClient.SNI.runtime dependency. Done means debugging starts without the dependency-resolution process exit.
