.NET 005: Xamarin with James Montemagno

.NET 005: Xamarin with James Montemagno

Episode Summary In this episode of Adventures in .NET, James Montemagno, a PM in the developer division at Microsoft working with Xamarin shares with the panel all of the exciting things happening in the Xamarin world. Charles Max Wood invites listeners to check out James’s appearances on a different DevChatTV podcast, The iPhreaks Show. Charles expresses his excitement to see Xamarin from a .NET perspective. James starts the discussion by sharing how he got into Xamarin and .NET. He explains what he loves about .NET. James worked for Xamarin during the transition into Microsoft, he shares what it was like and how the unification of the two made their products even better. The panel discusses the changes in Microsoft’s practices over the past ten years, becoming more opensource friendly and less focused on selling products. What is Xamarin, is the next thing the panel answers. James explains that Xamarin helps developers build native apps in C#. He goes on to explain how the versions of Xamarin change based on the platform, Android, iOS and tooling inside visual studio. The topic turns to how Xamarin runs. James explains that there is a common theme in Xamarin, flexibility. Choosing how Xamarin is run is up to the developer, who can use AOT (ahead of time) or JIT (just in time). Charles explains what AOT and JIT mean and how they affect application size and performance. James explains how Xamarin runs differently for Android and iOS. James introduces a brand new mode called Startup Tracing and explains how it can reduce the start-up time for your Xamarin apps by up to 60% by using a small trace of AOT. He shares the future goals for this mode and explains that it is free and can be used today. The next concern the panel has is about sharing code between different platforms and how this works with Xamarin. James explains that this problem is solved with Xamarin forms, Xamarin forms has everything a mobile app developer could want. In Xamarin forms developers can create pages to share cross-platform or simply build their whole app for all platforms. James even explains how a developer can make platform-specific adjustments to the code. James defines customer-driven development and explains how this allows them to create the best product for developers. The flexibility and capabilities in UI’s and controls allows developers to choose what their app looks like. Caleb asks about the built template components that allows the developer to architect the navigation in their applications. James explains one of the tools, Shell and how it helps you set up your navigation how you want it while handling all the messiness with minimal code. Charles asks James about library integration into Xamarin. James starts by sharing what comes in the box with Xamarin, 100% API coverage for both Android and iOS. How this works is, a team looks at the needs of developers and makes a list of the necessary, popular and desired libraries and creates API bindings for them. Libraries that don’t make that list can have a binding generated with Xamarins binding generator, which will include the necessary features needed to use the library. The panel changes the topic to the new Xamarin features that James is most excited for. James mentions a one-stop library called Xamarin essentials that will hold all the things a developer might need. He also includes Xaml hot reload for Xamarin forms, this feature will create a better level of productivity as it reloads around typos and mistakes allowing developers to stay in their workflow. The panel discusses the other benefits of a feature like this. Caleb Wells warns how addictive a good hot reload can be. The episode ends with James giving advice and resources for getting into Xamarin. Charles praises the Microsoft documentation. Caleb gives an endorsement for Microsoft Learn. Charles invites listeners to suggest topics and guests at devchat.tv. Panelists

There is a lot that goes into interviewing for a job, both for the interviewer(s) and the interviewee. The panelists talk about their experiences over the years from both sides. What questions should you ask? What shouldn't you ask? Should coding be involved or not? How many interviews should you expect to have at one company? Do you cast a wide net when interviewing or do you focus on a couple of companies? We discuss all of these questions and more. What advice would you give someone interviewing for a position?

What is a BFF? - .NET 110

Wai and Caleb sit down to discuss how authentication is evolving and how it works in Blazor. Identity server is now Duende server and with that comes the Backend for Frontend (BFF) pattern. From an authentication persepective this pattern can benefit SPA's because of the way it handles cookies and tokens. Caleb is in the process of integrating a .NET 6 Blazor app with Identity server 4 (IDS4) and wanted to use BFF but it isn't an option. We discuss alternatives and how those alternatives might be viewed from the business and developer perspectives. Join us and find out where Caleb ended up on his authentication journey.

Mastering SignalR - .NET 109

Mastering SignalR - .NET 109

Have you ever used SignalR in your development? .NET might have used it for the code you wrote and you didn't realize it. Kevin Griffin has used SignalR for multiple projects over the years and joins us to discuss how you can use it in your development. SignalR uses a pub/sub model and is great for applications that need immediate feedback. Kevin used it for a city's emergency system to provide alerts to first responders within seconds of an emergency being recorded. Like most technologies SignalR can be problematic if used incorrectly. We get to hear a couple of stories where Kevin had to work to fix troublesome SignalR implementations. Have you developed applications that could benefit from using SignalR?

Grokking gRPC - .NET 108

In today's episode Mohamad Lawand helps us try and grok gRPC. gRPC is a modern open source high performance Remote Procedure Call (RPC) framework that can run in any environment. That description doesn't really demystify what gRPC can do so Mohamad helps us fill in some of the gaps. We find out how gRPC works in .NET, how it works with HTTP, how it is different from REST and some good use cases for using it in your applications. gRPC is used by companies like Netflix and Square and is supported by the Cloud Native Computing Foundation. Have you used gRPC in your applications? Let us know on Twitter at @dotnet_Podcast.
