icomponent | super simple , render-agnostic component library | Web Framework library

I'm building a blazor webassembly site and I want to use bunit for testing purpose.

I run into trouble with components that use localization, I am getting the following error:

System.InvalidOperationException Cannot provide a value for property 'L' on type 'Path.To.Component'. There is no registered service of type 'Microsoft.Extensions.Localization.IStringLocalizer`1[Path.To.Component]'. at Microsoft.AspNetCore.Components.ComponentFactory.<>c__DisplayClass7_0.g__Initialize|1(IServiceProvider serviceProvider, IComponent component)

I already tried to install localization on the test project, but this did not work.

What are the differences between this syntax? What types will they have?

eg:

I have following project structure:

• Project.Server
• Project.Client
• Project.Application
• Porject.Shared

I want to create ExportManager that I would use for exporting data into Excel using closedXML library. So I have created following files into Project.Application:

IExportManager.cs:

I've been following this tutorial on the ABP docs site to learn ABP (using Blazor Server and EF Core ABP template).

The code for the issue I am encountering is available on my Github (I've created a tag for the issue).

I'm not doing it exactly the same, instead, I'm using Person as my entity instead of Book (making a sporting club management system instead of a book store).

I completed Part 1 of the tutorial and the correct API endpoints were created and I am able to use them to perform CRUD operations.

I am now on Part 2 of the tutorial and the "list page" is not loading.

This is the error I see in the browser dev tools.

I am started to work on a project with DevExpress 7.1.4 (old version 2007) and when I am trying to open the report I am getting the following error: The MenuBar parameter must be a boolean

If someone had the same problem and how can it be solved? please, write about it. Thank you.

UPD: I found that 7.1.4 is not compatible with vs17, but I can't know any idea where I could open the report by 7.1.4

I have, as I thought, a pretty simple task: render a React component according to its name/type.

Here is example of usage:

In my .Net CORE 5 (imported support files v5.0.12) Blazor PWA VS-2019 solution, I "had" a working 'Customer'-(data/app)service and Blazor pages to List and CRUD the Customer records (works as expected). I created similar 'Vehicle' files for both the SERVER-project and the CLIENT-project (of course changing the model field-references).

There are NO compilation errors yet, when I try to show the "VehicleList" page, this error appears in the Output-window:

crit: Microsoft.AspNetCore.Components.WebAssembly.Rendering.WebAssemblyRenderer[100] Unhandled exception rendering component: Cannot provide a value for property '_vehicleService' on type 'MyCore5AppPWA.Client.Pages.VehicleList'. There is no registered service of type 'MyCore5AppPWA.Client.Services.IVehicleService'. System.InvalidOperationException: Cannot provide a value for property '_vehicleService' on type 'MyCore5AppPWA.Client.Pages.VehicleList'. There is no registered service of type 'MyCore5AppPWA.Client.Services.IVehicleService'. at Microsoft.AspNetCore.Components.ComponentFactory.<>c__DisplayClass6_0.g__Initialize|2(IServiceProvider serviceProvider, IComponent component)

Please note the above notation of "...c__DisplayClass6_0..." that is curious to me (not knowing the significance of this). I have read many of the similar questions/answers related to the subject of this post that do not correct the error.

Here is a snippet from the Startup.cs file:

I'm trying to implement a create functionality for my PC Components ASP.NET MVC application using EF 4.7.2 and inheritance to handle all derived classes in a single method.

The problem is submitting the Component_CreateCPU.cshtml form converts the derived class of CPU to its base class Component in the /Components/Create action.

I tested instantiating a new CPU object in Index() and passing it into the Create() method and it retained it's derived class.

Is there any way to submit the view form and ensure the derived class is being passed in?

Model classes:

I am trying to register a service which uses a IHttpClientFactory in the startup.cs. I get an exception when I access the page where I injected this service (it does start up). I tried using an HttpContext instead of a factory and then I do not get the following error.

Error:

InvalidOperationException: A suitable constructor for type 'dida.Data.Member.MemberService' could not be located. Ensure the type is concrete and services are registered for all parameters of a public constructor.
