-Durable Functions projects targeting the .NET isolated worker can add the [Microsoft.Azure.Functions.Worker.Extensions.DurableTask.SqlServer](https://www.nuget.org/packages/Microsoft.Azure.Functions.Worker.Extensions.DurableTask.SqlServer) package by running the following `dotnet` CLI command:
-
-```bash
-dotnet add package Microsoft.Azure.Functions.Worker.Extensions.DurableTask.SqlServer
-```
