+name: API proposal
+about: Propose a change to the public API surface
+title: ''
+labels: [Feature Request, Concept-API]
+assignees: ''
+
+---
+
+## Background and Motivation
+
+<!--
+We welcome API proposals! We have a process to evaluate the value and shape of new APIs. There is an overview of our process [here](https://github.com/dotnet/roslyn/blob/main/docs/contributing/API%20Review%20Process.md). This template will help us gather the information we need to start the review process.
+First, please describe the purpose and value of the new API here.
+-->
+
+## Proposed API
+
+<!--
+Please provide a sketch of the public API signature diff that you are proposing. Be as specific as you can: the more specific the proposal, the easier the process will be. An example diff is below.
+You may find the [Framework Design Guidelines](https://github.com/dotnet/runtime/blob/main/docs/coding-guidelines/framework-design-guidelines-digest.md) helpful.
+https://github.com/dotnet/roslyn/issues/53410 is a good example issue.
+-->
+
+```diff
+namespace Microsoft.CodeAnalysis.Operations
+{
+     public class ISwitchExpressionOperation
+     {
++        public bool IsExhaustive { get; }
+     }
+```
+
+## Usage Examples
+
+<!--
+Please provide code examples that highlight how the proposed API additions are meant to be consumed.
+This will help suggest whether the API has the right shape to be functional, performant and useable.
+You can use code blocks like this:
+``` C#
+// some lines of code here
+```
+-->
+
+## Alternative Designs
+
+<!--
+Were there other options you considered, such as alternative API shapes?
+How does this compare to analogous APIs in other ecosystems and libraries?
+-->
+
+## Risks
+
+<!--
+Please mention any risks that to your knowledge the API proposal might entail, such as breaking changes, performance regressions, etc.
+-->
