+
+Currently available in public preview, Pulumi's Automation API lets you to programmatically call upon the Pulumi engine to provision your infrastructure. Today, we are excited to announce C# support for Automation API, enabling .NET developers to automate infrastructure deployments, create complex orchestration workflows, build custom ops tooling, and build cloud frameworks. Read more about the Automation API [here]({{< relref "/blog/automation-api" >}}).
+
+## Using Automation API in .NET
+
+The `Pulumi.Automation` [NuGet package](https://www.nuget.org/packages/Pulumi.Automation) exposes a `LocalWorkspace` for  creating and managing Pulumi [Stacks]({{< relref "/docs/intro/concepts/stack" >}}), and a `WorkspaceStack` that is a programmatic representation of a Stack for updating, refreshing, previewing, and destroying cloud resources. The Automation API makes it trivial to run Pulumi programs inline:
+
+```csharp
+var program = PulumiFn.Create(() =>
+{
+    var bucket = new Pulumi.Aws.S3.Bucket("s3-website-bucket");
+
+    return new Dictionary<string, object?>
+    {
+        ["bucket_name"] = bucket.BucketName,
+    };
+});
+
+var stackArgs = new InlineProgramArgs("projectName", "stackName", program);
+using var stack = await LocalWorkspace.CreateOrSelectStackAsync(stackArgs);
+
+await stack.Workspace.InstallPluginAsync("aws", "v3.30.1");
+var result = await stack.UpAsync();
+var bucketName = result.Outputs["bucket_name"];
+```
+
+You can use your existing Pulumi projects and invoke them from the Automation API:
+
+```csharp
+var stackArgs = new LocalProgramArgs("stackName", "C:\path\to\pulumi\project\dir");
+using var stack = await LocalWorkspace.CreateOrSelectStackAsync(stackArgs);
+
+await stack.UpAsync();
+```
+
+Since the Automation API can be invoked and debugged like any other code, it enables you to put together complex deployment workflows such as a blue-green deployment model:
+
+```csharp
+using var workspace = await LocalWorkspace.CreateAsync(new LocalWorkspaceOptions
+{
+    Program = PulumiFn.Create<ApplicationStack>(), // use your existing Pulumi.Stack implementation
+    ProjectSettings = new ProjectSettings("projectName", ProjectRuntimeName.Dotnet),
+});
+
+// your "blue" production code is already running
+
+var green = await WorkspaceStack.SelectAsync("green", workspace);
+await green.UpAsync();
+
+// do your cutover to "green" logic
+// and then teardown "blue"
+
+var blue = await WorkspaceStack.SelectAsync("blue", workspace);
+await blue.DestroyAsync();
+```
+
