+# `Azure.AI.Agents.Persistent` package Extensions Methods for Agent Framework
+
+## Context and Problem Statement
+
+To align the `Azure.AI.Agents.Persistent` package and Agent Framework a set of extensions methods have been created which allow a developer to create or retrieve an `AIAgent` using the `PersistentAgentsClient`.
+The purpose of this ADR is to decide where these extension methods should live.
+
+## Decision Drivers
+
+- Provide the optimum experience for developers.
+- Avoid adding additional dependencies to the `Azure.AI.Agents.Persistent` package (and not in the future)
+
+## Considered Options
+
+- Add the extension methods to the `Azure.AI.Agents.Persistent` package and change it's dependencies
+- Add the extension methods to the `Azure.AI.Agents.Persistent` package without changing it's dependencies
+- Add the extension methods to a `Microsoft.Extensions.AI.Azure` package
+
+
+### Add the extension methods to the `Azure.AI.Agents.Persistent` package and change it's dependencies
+
+- `Azure.AI.Agents.Persistent` would depend on `Microsoft.Extensions.AI` instead of `Microsoft.Extensions.AI.Abstractions`
+
+- Good because, extension methods are in the `Azure.AI.Agents.Persistent` package and can be easily kept up-to-date
+- Good because, developers don't need to explicitly depend on a new package to get Agent Framework functionality
+- Bad because, it introduces additional dependencies which would possibly grow overtime
+
+
+### - Add the extension methods to the `Azure.AI.Agents.Persistent` package without changing it's dependencies
+
+- `Azure.AI.Agents.Persistent` would depend on `Microsoft.Extensions.AI.Abstractions` (as it currently does)
+- `ChatClientAgent` and `FunctionInvokingChatClient` would move to `Microsoft.Extensions.AI.Abstractions`
+
+- Good because, extension methods are in the `Azure.AI.Agents.Persistent` package and can be easily kept up-to-date
+- Good because, developers don't need to explicitly depend on a new package to get Agent Framework functionality
+- Good because, it introduces minimal additional dependencies
+- Bad because, it adds additional dependencies to `Microsoft.Extensions.AI.Abstractions` and these additional dependencies add up as transitive to `Azure`.AI.Agents.Persistent`
+
+
+### Add the extension methods to a `Microsoft.Extensions.AI.Azure` package
+
+- Introduce a new package called `Microsoft.Extensions.AI.Azure` where the extension methods would live
+- `Azure.AI.Agents.Persistent` does not change
+
+- Good because, it introduces no additional dependencies to `Azure.AI.Agents.Persistent` package
+- Bad because, extension methods are not in the `Azure.AI.Agents.Persistent` package and cannot be easily kept up-to-date
+- Bad because, developers need to explicitly depend on a new package to get Agent Framework functionality
+
+## Decision Outcome
+
+Chosen option: "Add the extension methods to a `Microsoft.Extensions.AI.Azure` package", because
+it introduces no additional dependencies to `Azure.AI.Agents.Persistent` package.
