C# and AWS Lambdas, Part 5 – Updating the Zip in S3 and Updating the Running Lambda, with Pulumi IaC
This post pulls together a few threads I’ve been working on - the creation of Lambda to run .NET, storing the zip in S3, and updating the .NET Lambda when the zip in S3 is updated. This one took quite a while to put together - the permissions, roles, and policies were not obvious and I hope it will be of help to you.

C# and AWS Lambdas, Part 4 – Storing the Zip in S3, Setup with Pulumi IaC

In the previous post, I showed how to use Pulumi to create a Lambda, API gateway and upload a zip of Web API application directly to the Lambda.

In the post I’m going to use S3 to store the zip of a simple .NET application (not a Web API app) and point the Lambda at it, bringing all the resources up using Pulumi. One drawback of using S3 to store the zip for a Lambda is that when you update the zip in S3, AWS doesn’t deploy the new zip to the Lambda, but I will show a way of handling that in the next blog post.

C# and AWS Lambdas, Part 3 – Pulumi IaC for Web API and an API Gateway

In this the third in a series of posts on using .NET in AWS Lambdas I build on the previous post where I connected a Http Gateway to a Lambda running a Web API application. In that post I built the infrastructure by hand, i.e. via the GUI, pointing and clicking.

In this post, I will show how to build everything with Pulumi.

C# and AWS Lambdas, Part 2 - Web API and an API Gateway
In the previous post I created a Lambda that executed a C# console application. In this post, I walk through creating a .NET Core 3.1 Web API application inside a Lambda and making it reachable from the web, just like a normal Web API application.

C# and AWS Lambdas, Part 1 - Hello World
First in a series of posts on using .NET with AWS Lambdas. It will start with the simplest example that converts a lowercase string to an uppercase string, but by the end, you will be running a .NET Web API powered by Lambda, fronted by an API gateway where all the infrastructure is set up by Pulumi - this will take a few posts over the next while.

Polly and Blazor, Part 3 - Dependency Injection
Using Polly with Blazor is simple, as I’ve shown in the previous two posts. In this, I will define the Wait and Retry Policy in the Startup, add it to the service collection and use dependency injection to pass it into the Razor page.

Polly and Blazor, Part 2 – Using the Context
When using Blazor and Polly there are a few ways to pass data from Polly back to the UI, this example shows how to do this with the Polly Context.

Blazor, Updating or Refreshing the Display During a Method Call
It is possible to refresh or update components on a Blazor page asynchronously in response to a task or tasks completing, here is an example.

Polly and Blazor, Part 1 - Simple Wait and Retry
A few weeks ago I gave a talk on Polly at Dotnetconf (you can check it out here), at the end, I got many questions about using Polly with Blazor, I had never tried it, but assumed it would work. In this blog, part 1 of a few on Polly and Blazor, I’ll show you how to get a simple retry mechanism up and working in a Blazor Server App. For now, I am not concerned with dependency injections, policy registries, or anything other fancy things in this post, that will come later.
