What Is .NET Aspire? The Insane Future of .NET! 

This is fantastic, please make a series and take this to the limits. Can we have different components like workers that consume service bus messages, how does one del with connection strings and so on. What aspire packages are there, and what do they offer. I am dealing with microservices, and bringing up the local environment means running this and that container, storage and service bus in Azure (storage could be also in the emulator), and running other parts in VS to do debugging, and then command line to fire up tests against this setup. it is really a pain everytime I want to debug

I've never tried distributed applications before because they are so overwhelming. Maybe this will be the start of something new.

Aspire looks pretty good and I'm excited to see where it goes. Your example is nice if everything is under one solution but we all know that's not how we dev in reality. What I'd like to know Nick is; how do wire up aspire when your frontend projects and APIs are in separate solutions?

This is huge. We use AWS cdk in our company and that is a pain in the neck. If this works for aws in the future, will be a big win

Great work by MS, and thanks Nick for bringing it up in very elegant way.

This is so cool. look forward to more on this.

Looks awesome, looking forward to the new videos about it.

This looks interesting, I’d love to see some follow up with practical use cases. I guess that’s a Dometrain course in the making 😂

That's a LOT of rope! Newbie bootcamp developer can now create an entire distributed system in a few hours and once deployed can accidentally rack up tens of thousands of dollars worth of compute time in a matter of seconds. Genius Microsoft :)

Great Video. Thanks. Looking forward to learning more.

Look very cool. This is definitely something to deep into. Thanks!

It's pretty cool. I usually add a docker-compose file to manage a fairly similar flow, including otel-collector and grafana stack images. It's much easier with Aspire. It would be great to learn how to use an Aspire based approach in a production environment. I'm guessing this will be supported out of the box for Azure, but not sure about Kubernetes and other cloud platforms. Thanks for sharing, lots of useful and inspiring content!

I was so hyped when seeing this!🎉 Can you please make a video on how to deploy that on azure and aws? And even perhaps on self hosted vServers? A lot people would benefit from this❤

Great intro video Nick, thanks for sharing it. MS documentation is also pretty sufficient to this point (e.g. I was wandering whether someone would still need Dapr and is answered in MS Aspire FAQs). I just wander if Aspire is tight to Blazor or you can have solutions with different frontend technologies.

Really appreciate the black friday deals. Money has been tight and ive been wanting to check out the logging class so finally picked it up!

Awesome! Will make writing code for distributed apps way easier!

This has to be one of the best thing coming out of .Net in a while. Hopefully they release a stable version.

This is such a cool advancement, can't wait to give it a try

This is a brilliant addition. It has the power of Azure Service Fabric without all the overhead and complexity. Nicely explained by Nick.

This is really cool project! Thanks for sharing!

An export to k8s yaml or at least to docker compose is a must. A can see that deployments been handled to the DevOps guys and the dev team like "I did the aspire thing"

This is a good feature for monitoring, thanks for sharing :)

now THAT seems pretty damn cool, can't wait for this to mature!

This is seriously cool! Just wish I had access to this a year ago when I was setting up a distributed application 😄

thats kind of an internal docker compose seems cool for fullstack devolpment using blazor, but do you see aspire useful for backend devs as well? btw, that dashboard is nice, is it available also without using the aspire builder?

Hey Nick, thank you for this Aspiring ;) demonstration. I am very interested in an example on how one can deploy an aspire application with containers. Where would the containers be hosted, how will they be deployed etc. Thanks!

I'm skeptical. How would it work for heterogenous systems (here I mean systems with components created using different programming languages/technologies)? Let's say I have a FE written in js/ts and not blazor? Or I have a BE component(s) written in go/ruby/rust/python/anything else? Also, as mentioned here multiple times, it will work painlessly only for monorepos.

Amazing!

Amazing! This is so coooool!

I could see this as being pretty useful where I work. Just wonder if there is a way to have it load an app into a browser tab by default and focus it, so when testing you don’t have to click the link in the portal to start testing your main project, but can still switch to the portal if you want.

awesome! thanks

As with many things I wish this was present when I started working on the setup I am currently working on... So much effort to change.

Super excited for this! Looks amazing. Can you do a video on how would set this up for micro services? I'm a little confused how you would get other solutions to recognize the app host unless you would publish it as a nuget package or something.

Simply AWESOME

Immediately thought of Project Orleans (and DAPR too). Use-case might slightly differ, but they solve most of the problems + introduce "actor" framework that is designed to solve async problems in distributed systems

@nickchapsas can you make a video on how we can create our own Aspire Components? I would like to use it to run containers locally for databases/services not currently offered.

wow, thank you. This is great, will make managing micro-services more easier

this is exciting

this is awesome!

This is really cool, and I love your enthusiasm! I would be keen to understand more about how to take this from local development to cloud deployment (I use Azure)

Thanks a lot.

This is beautiful

Wow. Neat.

I love this!

I love this, but i really wants to see what it looks like with a lot of microservices in a fully fledged application. Also, we're gonna have to wait for extra tooling to bring none dotnet based web pages to aspire (because i'd love to monitor my react to the same interface while debugging). I also don't mind containers and apis to be different pages. There's other UIs choices (like the metrics filters being unreadable) that are more important to tackle first IMO

Might be useful for smaller, new projects that are tightly integrated to .NET. One fundamental issue I see is that it seems completely tied to monolith repos. How is it supposed to work in a microserviced architecture without having annoying git submodules all over the place?

This seems like it could be really powerful. From what I understand from your video, this is similar to creating a docker compose project.

Thanks

Thanks Nick and this is awesome. I don't know why people are getting upset about any slight overlap with Docker/K8S. A big part of this is simplifying configuration of multiple projects running locally, including configuring everything so all the various nuget packages used (SQL, Redis, etc) and logs, metrics, configuration are all visible in a simple console and easy to work with. How does docker help me wire up my nuget packages with such best practices to see this type of telemetry locally?

This is very cool. I look forward to your next videos. I'll have to check the .NET Conf content, but the three things that I'd like to know about are: 1) what's the auth story? can we set up and mock client apps to delegate to a provider like Entra or Google? 2) what's the best practice for protecting the API with token-based auth? roll-your-own with filters, or is there something out of the box in Aspire? 3) what's the native client story? anything that works for Blazor webassembly that wouldn't translate to Blazor hybrid (MAUI/WPF/WinForms)? interested in that answer for both auth, and just in general.

@nickchapsas, thanks for the video! I’d love to see your thoughts on Dapr someday.

To be honest, starting in the middle of the video, I just sat with my mouth open in surprise and admiration. This deserves every imaginable and unimaginable ovation towards the developers of this product! Bravo! Nick, need more information/tutorials on working with this project!

"Best Practices" has become the phrase that directly translates to "Whatever will allow Microsoft to continue to take the maximum money they can from you". If they were truly interested in helping companies innovate, there would be comprehensive and simple upgrade paths from the last version of their web framework to the next. There is no "evolution path" because there's no money in that. However, there is money to be had in Microsoft Consulting rebuilding your product for you from scratch... again and again. I was on that side of the fence for a long time and I know how it works. Small development teams cannot keep up with Microsoft's pace at the same time they are trying to implement their own company's internal requirements. And don't get me wrong... I've been 100% in the Microsoft development camp since the 80s and have never strayed from that path. Although, now, it's no longer a walking path but a 10-lane highway with no speed limit and everyone is getting run over.

this is amazing

Intressting!

hi Nick, you are, in my view, one of the most reliable and resourceful mentor for many developers currently. May i suggest however, that you slow your speech down so that your videos speak to us, rather than hurrying to get to the end. I think many do not mind sitting to your 2 hour videos, so the length doesnt throw us off...pretty please

Put out the "way more Aspire content"! NOW! This looks awesome! And: When will Aspire be out of preview?

cool I didn't understand at first from launch post is it kubernetes in IDE. Though this video upload schedule made me check calendar in case I haven't been missing a workday

Sounds awesome 👍 But do you think you should use this already like in the example for an api and frontend or only for more complex structures?

Very cool, what do you think the future of this will look like? Will it stick around?

Aspire is the best that happend since a long time!

My architect always says "microservices is not a technical implementation per-se, it is a team management implementation" (Before anyone comments, i know there are additional technical benefits to microservices!) We moved away from Monolithic applications because 20 developers all working on the same project step on each others toes... so we will break our application up into services, now each team could own a service or whatever.... but now my application is not a SLN with 30 services(and each "service" could have 2-3 CSPROJ projects!) but separate repo's with their own commit lifecycle and release lifecycle.. We are shipping individual services to production 2-3 times a day.... not sure how this will overcome that..

Amazing.

Looks really cool! How would this work with multi platform/language orchesration?

Amazing

How do you secure the dashboard. I mean if you run this in a production environment, can you add access rights to it? And can you also see to it that some environment variables are masked, as in some situations there is one team handling the system and another team handling the development and they aint usually allowed to access passwords but they are interested in seeing logs.

what is the terminal that you are using? Looks very nice :)

What that is really insane dealing with all that will be tricky but reaching docker is crazy thing this is going to be the Futcher of distributed systems

Can you please extend the usage of Aspire with Identity for example, and how to keep all the authorization and authentication separate from the frontend?

I remember reading about them adding the workload commands to the dotnet CLI earlier this year, but I feel like it wasn't described why. I guess it was added because of Aspire, and Aspire was still on the down low. Fair enough

.Net Aspire has WingLang written all over it. I love it, and can't wait to put it to good use. :)

A lot of microservices I want to have option to add projects from different repos, is there any way to handle this? Thank you very much for content!!

I’m curious, can you step debug between different projects with aspire now?

Great introduction. From my perspective it feels like Aspire tries to solve.a problem where teams have a lot of distributed applications... but is the solution really another tool, or maybe it should be to consolidate some of the applications? With that said, I do think it is good that they are pushing more good defaults with otel and also makes it easy to connect things locally. I also wonder how, and if, it is possible to include something like a nextjs application into this world? I mean, create API in .NET, use docker for redis, and what do I do with an "external" thing like a nextjs application?

Wow.. Just wow

Can we use this in frontend spa apps like react, nextjs, angular?

Is there a way to have it multirepo? Since we're speaking about microservices would be great to have services divided in different git repositories (without submodules) but it doesn't seams so easy. I mean, you need references for all the projects in that AppHost

Can I use this to do end-to-end testing?

So many questions left. Please continue describing the topic. For instance how service descovery exactly works. Do you know something about Microsoft Orleans?

Whether it can be used to react (frontend) and core (backend) project?

Does it work only with blazer frontend? What about other frontend frameworks: Angular, React, Vue?

Really cool, but what about solutions that are spread across teams, not sharing repos or solutions file?

Look. I was specialized in C# in 2010 instead of Java, thinking it would replace it. If 20 years of efforts of a monopolistic corporation that comes preinstalled in every computer of the planet, have not been enough to give C# any meaningful adoption... I wouldn't expect it any time soon.

Hi, Data erased from the dashboard while we restart the editor. Any support / ideas to retain the data for local development?

My brain has just exploded. All these new things that Microsoft did for C# are insane. Thank you for giving us knowledge for all these new features.

Video on how aspire will work on multiple environments like dev , qa , prod ?

Maybe ok for small projects, but seems counter to solving dev team issues. Which is why microservices, etc are used to replace a monolith.

Looks amazing, can i scale horizontally with this ? For example put everything inside docker and distribute my app among nodes

This is all nice, but I always roll my eyes when you get something "out of the box" and have to trust that it's doing what it's supposed to do. I like to have manual control over things.

So how is it distributed? It’s running on your single PC. How do we use it in kubernetes?

Its actually like full elastic + rancher + docker hub and metrics and more holy shit.

what is this commandline highlighting that you have here?

What's the purpose of this tool? Is it supposed to be use in production or in development? Is it going replace Application Insights and/or Elastic APM?

how scaling works? how deployments done on different cloud provider? how it will work on Kubernetes cluster? how it will work on on-prem server farms?

Can i use Aspire on project running multiple solutions?

I need to see how to containerize this whole app and then deploy with azure ci/cd pipeline. This is critical for any modern environment to be presented.

Looks like this requires teams to work on the same solution. Could be difficult

In the traces, how does It work for database queries ? For example, If the backend runs a entity framework query, Will the trace show the query and How much time takes to run ?

can i use api and wpf for client?

Does the API need to be in .net 8? Or can I use dotnet 7?
