Client side performance is important for better user experience. Optimizing and efficiently serving the static resources (JS, HTML, CSS, Images etc.) significantly increases client side performance. This Java Library provides web components to help you speed up Front-End of your J2EE application. It is said that 80% of the end-user response time is spent on the front-end. To make the front-end efficient and friendly to the browser, various [Performance Practices] have been suggested. We can measure page performance using tools such as [YSlow] or [Page Speed] These tools validate page against the best practices and give the performance ratings/grade. WebUtilities provides inbuilt J2EE components to apply some of those best practices in your web application with minimal change to speed it up and get higher performance score.

QUESTION
I have a web.api action that accepts multipart/form-data via streaming, so it doesn't have any arguments:

Answered 2021-May-21 at 10:21Since in .Net web api the controllers derive from ControllerBase
, they all have a HttpContext
instance property, you can use its RequestAborted
token.

QUESTION
I am working on an asp.net core mvc project (.net 5) but struggling hard with Identity related things.
I have a class HedgehogUserAccount
that inherits from IdentityUser
with two other classes that inherit from HedgehogUserAccount
: CustomerAccount
and UserAccount
(bad choice of name, I know - I will change it when everything works). After a lot of work, I have managed to get the migrations to work and the program compiles and runs, but when I try to register a User
I get the following error:
NotSupportedException: No IUserTwoFactorTokenProvider named 'Default' is registered.
The error comes from line 90 in my registration code (see full code pasted below - it is almost the same as the scaffolded registration page):
var code = await _userManager.GenerateEmailConfirmationTokenAsync(user);
The relevant (I think) part of my Startup.cs looks like this:
...ANSWER
Answered 2021-May-04 at 10:31After a lot of headaches, I have now reached a conclusion to my problem. I solved it by implementing my own token provider and registering it with the system. In case anyone else crashes into the same wall as I did, I leave my solution here.
Step 1: Implement IUserTwoFactorTokenProvider
QUESTION
I use Identity and can't access the confirmation page (There is no transition to another page from the Register page). Using migrations, I created tables for users, but by clicking the "Register" button, this page is refreshed.

...ANSWER
Answered 2021-Mar-11 at 09:10Seems your register failed (maybe the user already exists), so it return back to the current page instead of going to confirm, while you didn't show the error message in the view, so you don't know if the account is successfully registerd.
Add this line to your custom Register view to show the error message:

I have the following configuration, but the ASPNETCORE_ENVIRONMENT variable doesn't make it to the CsProj config.
.vscode/launch.json

Answered 2021-Jan-12 at 06:12I think you might need to move the environment variable from env

QUESTION
In ASP.Net Core, I have this action method:
...ANSWER
Answered 2020-Dec-21 at 20:58I have confirmed if I search for FormFileValueProviderFactory
in the ValueProviderFactories
in my DisableFormValueModelBindingAttribute
, I can find it by simply doing a Where(p => p.GetType().Name == "FormFileValueProviderFactory").FirstOrDefault()
. Then if I remove it from the factories list, everything just works.
So the question now becomes why cannot I reference that type. Since I have the type pulled up I can look at the assembly being referenced and it is C:\Program Files\dotnet\shared\Microsoft.AspNetCore.App\3.1.10\Microsoft.AspNetCore.Mvc.Core.dll
. This means it is not even using the NuGet at all, but is using this assembly. So I began removing older and unnecessary NuGet references when I discovered why this project is set up this way. There are some ASP.NET Core MVC utilities in a helper library, including the DisableFormValueModelBindingAttribute
. This library is currently configured to be netstandard2.1
, which is why the ASP.NET Core stuff cannot be referenced.
To fix this, all I had to do was change the target framework to be netcoreapp3.1
and add this to reference ASP.NET Core:

Answered 2020-Sep-28 at 09:07You are not actually adding roles to the token. Each role should be a claim, like this.

There is one important thing though that is not mentioned there - you have to remove the default binders. Otherwise buffering will kick in. Here is is how - Upload large files with streaming.
