MobileBlazorbindings in the experiment has got a good response. We hope that it can become a formal project of Microsoft as soon as possible, and can provide complete functions, so that users can focus on their own business logic, especially the hybrid applications. It seems to have a chance to surpass electron, more streamlined but more powerful.

Feature Request: Drop-in component for ASP Identity Administration, Portals, UI, SSO, Claims, AD-Sync, Token, Multi.Tenant Management so that the Visual Studio templates don't require commercial licensed 3rd party components.

I have been watching/waiting few yrs. patiently, however some recent changes have forced me to request -- Microsoft revisit this for their developer community, keeping in mind some of the pricing out there compares to the salaries of 10 to 15 developers in Bangladesh, Vietnam, India, Philippines etc.

Core & Basic need, yet very complex and critical.

There's a void in .NET native drop-in solution, unlike the Java, PHP Stacks etc, where there are many native drop in Identity Administration & Management Frameworks options that are leveraged across all their platforms seamlessly by developers, for e.g. the J2EE Pluggable Identity Management Framework or JSR 168 or JSR 286 or JSR-351 or JSR-375.

Why is this important? because using Java or PHP, it has allowed easy, clear, core and basic functionalities in those native stacks. As a result if you look JSR 168 or JSR 286 or JSR-351 or JSR-375 Multi-tenants, Group to roles, or to claims vice versa is so easy vs. NET , mobile devices, portals, they all work seamlessly and cohesively with security fixes managed by either IBM or SalesForce or Oracle or Red Hat etc. This is enables developer to be productive right out of the gate.

In .Net there is void/very limited support, always requiring a combination of 3rd parties as a barrier to entry & adoption of ASP app. This is non-trivial for developers and security vulnerability that requires the attention of Microsoft Experts.

Example: We have private information sharing site non OSS for the community almost free (pay if you want), and when we started with web forms, then Simple Membership, the Identity, Identity 2 ASP MVC we had implement much of it on top of these from scratch, when we moved to .NET Core it was another effort. Besides the development there was a lot of confusion on the internal concepts and how they now meant new things. Roles, Claims, Federation, SAML then SAML 2.0 and then Open ID 2.

Describe the solution you'd like

• A drop-in is extensible solution that supports ASP Identity eco-system, Administration, UI, SSO, Token, Multi-tenant Management
• A configuration section to turn on-off the various features.
• Embedded into VS Templates (remove Identity Server, use native MS option etc.)
• Allow-Easy AD Active Directory Integration
• User Defined/Created Fields UDF from the Admin level Support.
• The current options and the pricing eliminate many of the existing applications from continuing usage on the .NET stack without extensive retooling or completely abandoning the MS framework.
• SAML2/CAS per @tbonham
• Allow template option Configuration.MultiTenancy.IsEnabled = true; Global DataFilter for Tenant entities

Its high time MS address this core gate-keeping feature!!

[papyr]

• Controller/API DDOS throttling support
• Login Controller/API Captcha Anti Spambot support
• Timeouts are easily by passed using Singal-R and there's no way to force anonymous connections to disconnect
• No way to handle anonymous chats on public website. For e.g. if Web User is Surfing/browsing for help or FAQ on product/chat on ASP website with SignalR, we have to create a duct-taped solution for this, there is no way to identify them uniquely to create a chat stream/session unless they login.

@mrkarMSFT thanks for the idea 👍 but they keep closing my feature requests and locking them, so its not able to upvote!

Can you please unlock 26594 to allow voting on the feature please!

Do you mean Like Skoruba.Admin then upvote #26594

[mnmr]

RFC 7692 (WebSocket per-message compression) for SignalR. It seems this depends on runtime#20004 but it seems relevant in this context. There was an old issue referencing this, but it is now closed and I could find no equivalent open issue here, so I am recommending that people upvote on the runtime issue.

@mrpmorris If you're in an environment where files with "dll" extensions are simply blocked, then we've provided manual steps for changing the extension. We haven't identified any additional work in this area currently. If you think we need to do more, please file an issue with your suggestion and we'll take a look.

Good morning, I hope I am not mistaken but I have noticed that the Timer () is
slows down when you switch tabs in the browser.
Make a basic example of the possible problems and this is my repository link (https://github.com/PercyLeon123/Cronometro).
To detail what happened, carry out some tests and record it.

Basic and simple example, slows down 10 minutes https://youtu.be/jHLVCSGXPMs
Example with more code, it slows down 1 minute and 50 seconds https://youtu.be/YhEVTVB2ai0
if you do not change the tab the timer does not slow down https://youtu.be/2NI0NhRLdFY

In the description I detail what happened. I'm Percy León from Lima-Peru
Contact me Linkedin
Greetings!

[mkArtakMSFT]

Thanks for reporting this, @PercyLeon123.
Can you please file a new issue to track this separately.

[RehanSaeed]

Most of the feature requests seem to be Blazor related. While this is understandable due to it being a new technology, with respect to my fellow Blazor devs there are still those of us who don't use Blazor for various reasons that are not important. I hope that development time is not biased too much in favour of that technology to the detriment of core ASP.NET features that would help everyone due to their being core features. Here are the top features according to upvotes:

• Add support for LetsEncrypt (LettuceEncrypt still needs DNS renewal) Add support for LetsEncrypt certificate acquisition and rotation in Kestrel #4712
• Add HTTP/3 Support [Epic] HTTP/3 support in ASP.NET Core #15271
• Add Streaming API Support to MVC Add Streaming API support to MVC #11558

• ProblemDetails is not returned for 404 NotFound and 500 ProblemDetails is not returned for 404NotFound and 500Exception #4953
• Update ASP.NET Core to use C# 8's nullable reference types Update ASP.NET Core to use C# 8's nullable reference types #5680
• Add IAsyncStartup and IAsyncStartupFilter to support async startup classes and filters Add IAsyncStartup and IAsyncStartupFilter to support async startup classes and filters #5897

We need SAML2 and CAS add to.

[papyr]

Auto Upgrade option PartialViews to ViewComponents Lots of legacy code is hung in the partials, we need to port that to the new ViewComponents or TagHelpers apps

[YohanSciubukgian]

Concurrent frameworks can support a wider range of architectures (this list might not be exhaustive):

• NodeJs support : x86 / x64 / arm32 / arm64 / ppc64le / ppc64be / x390x
• OpenJDK support : x86 / x64 / arm32 / arm64 / ppc32 / ppc64le / s390x / sparcv9
• AspNet core support : x86 / x64 / arm32 / arm64

please add support to more architectures.

[richlander]

Thanks for the feedback @YohanSciubukgian. Our plan is to support most/all mainline OSes and chip combinations. We now have that. At present, the only one we're really missing is Linux x86 (32-bit). That comes up quite seldom. The additional ones that you've mentioned come up even less. The community is free to add the more niche configurations that you'd mention, but I'm doubtful that will happen. They don't, AFAICT, have any practical commercial value.

Personally, I'd much rather we added support for FreeBSD (on x64) than PPC. I suspect that would benefit an order of magnitude more users (if not much more).

Also note that we're currently putting a fair bit of effort into supporting Apple Silicon and Arm64 (generally). Just supporting new chips takes a lot of investment. Context: dotnet/runtime#43313 and https://devblogs.microsoft.com/dotnet/arm64-performance-in-net-5/. It is much better to focus on doing a great job for mainline chips and leave the legacy/hobbyist chips for other platforms to support.

There is a company working on MIPS support for .NET Core currently: dotnet/runtime#38069.

Thanks for your answer. I don't know if it's possible but as you had merged mono in dotnet/runtime repo for .net 5, I had in mind to expose existing architectures initially developped for mono but with official Microsoft support.

[richlander]

Great question. The Mono in dotnet/runtime is targeted at Android, iOS, and wasm.
