Decisions about ASP.NET Core

ServiceStackServiceStack

I am currently using ServiceStack nuget package which has a dependency on ServiceStack.Common nuget package which in turn uses System.Common.Data.dll file. Now this dll file is not supported by .NET standard version 2.0.

Hence my whole project is in limbo. I want all the dependencies should either support .NETStandard 2.0 or .NET Core 6 version.

Now I can only get .NET Core 6 when I replace ServiceStack nuget package altogether with ASP.NET Core.

Has anyone faced this before? Thanks.

and
SlackSlack

Hi everyone! I am trying to implement a chat module in my product but it is not stable. My backend is in ASP.NET Core with EF Core, and my frontend is in Angular. Since I am already using dotnet, I used SignalR as a socket connection provider. At the moment, it works when the user logs in, the chats are loaded and the user is notified if there is any unread message just like any other app does by displaying a badge and number of unread chats. When the user navigates to chat, it loads the messages of chat. To avoid user waiting for messages I have stored the messages locally in a state management store and when the user switches the chat, it first loads messages from the store and then sends a request to server if there is any other message that is not on local.

The problem starts with multiple connections when single account is connected from multiple clients/browsers. From backend, I check if user is connected to SignalR socket then I send the message to all connections of user it does not work properly, this part is highly unstable. secondly, How can I improve the response of message loading? I only load 25 messages at the start.

Is there any article describing how Slack, Google Chat or MS Teams is handling the browser chat? it would be of great help.

Thanks

and
SpringSpring

Hello, I am trying to learn a backend framework besides Node.js. I am not sure what to pick between ASP.NET Core (C#) and Spring Boot (Java). Any advice, any suggestion is highly appreciated. I am planning to build only Web APIs (no desktop applications or something like that). One thing to mention is that I have no experience in Java or C#. I am trying to learn one of those 2 and stick to it.

UPDATE: The project I am trying to build is a SaaS using microservices that supports multi tenancy.

I'm looking to develop a website. My current plan is to use ASP.NET Core 5 web api for backend and React for front end. But not long ago I hear of Next.js and that it is capable to have all backend inside Next.js. If so, is it still worth using .Net + React (or some other combination of frameworks).

ASP.NET Core Alternatives & Comparisons

What are some alternatives to ASP.NET Core?
ASP.NET
.NET is a developer platform made up of tools, programming languages, and libraries for building many different types of applications.
Django
Django is a high-level Python Web framework that encourages rapid development and clean, pragmatic design.
Spring Boot
Spring Boot makes it easy to create stand-alone, production-grade Spring based Applications that you can "just run". We take an opinionated view of the Spring platform and third-party libraries so you can get started with minimum fuss. Most Spring Boot applications need very little Spring configuration.
React
Lots of people use React as the V in MVC. Since React makes no assumptions about the rest of your technology stack, it's easy to try it out on a small feature in an existing project.
Blazor
Blazor is a .NET web framework that runs in any browser. You author Blazor apps using C#/Razor and HTML.
