Adds a new 'dotnet new' template (shortName: lambda.DurableFunction) under Blueprints/BlueprintDefinitions/vs2026 that scaffolds a Lambda durable execution workflow using the Annotations class-library programming model on the managed dotnet10 runtime. The sample workflow demonstrates the core durable primitives: StepAsync, a step with an exponential RetryStrategy and AtMostOncePerRetry semantics, WaitAsync (suspend timer), and RunInChildContextAsync. The generated serverless.template includes DurableConfig and the AWSLambdaBasicDurableExecutionRolePolicy managed policy. A test project drives the workflow locally via Amazon.Lambda.DurableExecution.Testing. Also registers the template in Blueprints/README.md.

Summary
Adds a new
dotnet newtemplate —lambda.DurableFunction— underBlueprints/BlueprintDefinitions/vs2026that scaffolds a Lambda durable execution workflow.[LambdaFunction]+[DurableExecution]) on the managed dotnet10 runtime (durable execution requires dotnet10).ProcessOrderworkflow demonstrates the core durable primitives:StepAsync— checkpointed stepStepAsync+RetryStrategy.ExponentialwithStepSemantics.AtMostOncePerRetryWaitAsync— suspend timer (no compute charge while suspended)RunInChildContextAsync— grouping related stepsserverless.templateincludesDurableConfigand theAWSLambdaBasicDurableExecutionRolePolicymanaged policy (kept in sync by the source generator).Amazon.Lambda.DurableExecution.Testing(no AWS resources needed).Blueprints/README.md.vs2026 only for now (matches the existing vs2026 layout convention).
Testing
Validated locally (durable preview packages packed into a local NuGet feed):
dotnet buildof the function project succeeds on net10.0; source generator emitsFunction_ProcessOrder_Generated::ProcessOrder, matching the handler inserverless.template.dotnet test— both unit tests pass, no warnings.dotnet new lambda.DurableFunction --name <X>instantiates correctly and the shortName resolves.Notes
Amazon.Lambda.DurableExecution.Testingis not yet published to NuGet; the template references0.0.1-preview. The test project will restore once that package is published (or via a local feed in the meantime)..autoverchange file needed (autover tracksLibraries/srcprojects only).
