Debugging Java script in old asp core app
Hy, I need to modify an asp.net.core app witch I made years ago. in version 2.2. I do succeed to alter C# code in visual studio (2022), but I need to alter also some Java script. The problem is that if I try to do so and I want to debug it it seems that the script in my browser (MS Edge) is not changing. I have enabled Java script debugging in VS. I emptied the browsers cache but nothing seems to help. When I run the application in debugging mode and hit F12 I still see the old script. Please help!
Is Native RDLC Report Support Planned for Future .NET Versions?
Good day Team, Given the demand for cross-platform reporting solutions, is there any plan to provide native RDLC (Report Definition Language Client-side) support for .NET Core or upcoming .NET releases (e.g., .NET 9 and beyond)? Many enterprise applications rely on RDLC, and the current lack of official support limits modernization efforts and forces continued reliance on the legacy .NET Framework or Windows-only workarounds. Is RDLC on the roadmap for future .NET versions, or should we consider alternative technologies for long-term reporting requirements? Any official guidance or updates would be greatly appreciated.Creating a pooled resource for Dependency Injection
Currently, we have AddSingleton(), AddScoped(), and AddTransient() to generate resources in DI. Is there a way to request a new feature for an AddPooled() which will allow us to create and reuse unused instances from a pool? I have a class that has an expensive creation (a little over 5 seconds) that cannot be instantiated as a singleton. I don't need it to maintain any state, so it would be an ideal candidate for a pooled resource in DI.When should I use SQL Server, MySQL, or PostgreSQL?
I'm working on a web application (using C#/.NET backend), and I need to choose a relational database. I'm considering three options: Microsoft SQL Server MySQL PostgreSQL I want to understand: What are the strengths and weaknesses of each? Which database is better suited for: Transactional performance Advanced querying / analytics Ease of use with .NET Cross-platform support Are there any licensing or hosting concerns I should consider? My use case involves: Moderate traffic Complex queries with joins APIs and background jobs Deployment to cloud (Azure) I’d appreciate any recommendations or real-world experience comparing these databases.
Help with my ASP.NET API Application
I have been developing API for a full stack application with React FrontEnd in ASP.NET for my Internship project which is an Asset Management System. I have successfully implemented API Endpoints for CRUD with Authentication with JWT. What topic should I learn next ? Should I start providing API Documentation or is there something else I need to learn ? I have also uploaded the Schema the project is using. I am using ADO.NET instead of Entity Framework for quering with the database. The link to my Repository Source Code: https://github.com/bibashmanjusubedi/Internship
Singleton Class with Async
I'm working on building a Blazor Web App (.net 9) for an internal company portal. I want to load some persistent data to be used throughout the app into a class and then load that class as a scoped service. Most of the data will be fairly static, but expensive data to retrieve, ie: graph api call for members of groups, etc. So that data will also be loaded asynchronously. Everything I've found regarding loading data into a class asynchronously basically points back to a post by Stephen Cleary on Asynchronous Lazy Initialization: https://blog.stephencleary.com/2012/08/asynchronous-lazy-initialization.html My question is, given that this post was originally posted back in 2012, is this still an acceptable way of loading data asynchronously for a singleton or are there other, more modern approaches to this scenario?aspnet c# iterate control in listview and remove a panel from placeholder in one column

Implementation SMTP using MailKit in ASP .NET Core MVC
I am developing a web development project, where I have to implement email trigger along with message. Suppose there is a form where users will put thier name, email, title and message. After hitting submit button it will automatically send the message to the owner. How can I achieve this in latest version of this framework. And MailKit is Version 4.11.0.Enable .Net ImageFormat.WebP in VS 2022 Prof ASPX Web.Config
Hi. I am developing C# ASPX Web sites in VS Professional 2022 (64 bit). I want to access the System.Drawing.Imaging.ImageFormat.WebP property so I can manipulate WebP files. I believe this requires .Net 4.8. I know there are 3rd party libraries out there - I would prefer to keep as much native MS code as possible. I am unable to get System.Drawing.Imaging.ImageFormat.WebP as a selection option for the ImageFormat. I can get all of the other formats e.g. TheImageFormat = System.Drawing.Imaging.ImageFormat.Jpeg/Gif/Png etc. WebP is not shown as an option. I have Web.Config set as: <compilation optimizeCompilations="true" debug="true" targetFramework="4.8.1"> <assemblies> <add assembly="System.Net, Version=4.0.0.0, Culture=neutral, PublicKeyToken=B03F5F7F11D50A3A" /> <add assembly="System.Numerics, Version=4.0.0.0, Culture=neutral, PublicKeyToken=B77A5C561934E089" /> </assemblies> </compilation> <httpRuntime targetFramework="4.8.1" executionTimeout="240" maxRequestLength="20480" requestValidationMode="2.0" /> The Targeting Packs & SDK seem to be installed & enabled as per the screen snap below. Any help in resolving this is greatly appreciated. Many thanks, Peter.
Build Scalable Web Apps and APIs with ASP.NET Core, Blazor, Angular for Modern Web Apps
I’m starting this discussion because many developers today need guidance on how to build modern, scalable web applications and APIs by combining ASP.NET Core, Blazor, and Angular—three powerful technologies within the .NET ecosystem. Whether you're focused on server-side development, creating dynamic client-side apps, or integrating both, these frameworks provide incredible capabilities to enhance your projects ASP.NET Core for API Development: ASP.NET Core is a robust, high-performance framework that allows you to create powerful APIs. Some of the best practices we’ll cover include: - Designing RESTful APIs with ASP.NET Core - Utilizing Entity Framework Core for efficient database access - Securing APIs with JWT and OAuth - Handling asynchronous requests for optimal performance - Implementing API versioning and changes over time Building Dynamic Web Apps with Blazor: Blazor enables you to create interactive web applications using C# instead of JavaScript. We will discuss: - Blazor Web Assembly vs. Blazor Server: Differences and use cases - Creating reusable Blazor components for UI - Integrating third-party JavaScript libraries with Blazor - Using SignalR for real-time features - Optimizing Blazor for performance Angular for Full-Featured Client-Side Development: Angular is a powerful, full-featured front-end framework that excels in creating dynamic and complex user interfaces. In this section, we'll dive into: - Why you might choose Angular over Blazor in certain cases - Using Angular CLI to scaffold, build, and maintain apps - Managing state in Angular with NgRx or RxJS - Connecting Angular with ASP.NET Core APIs for data handling - Working with Angular components, services, and routing for a seamless user experience Combining Angular and Blazor in a Single Application: You may have use cases where you want to combine both Blazor and Angular in one application to leverage the strengths of each framework: - When to use Angular for complex frontend features (e.g., dynamic forms, complex data visualization) and Blazor for simpler components or backend-heavy apps. - Managing communication between Angular and Blazor components in a single page (e.g., using - JavaScript Interop to pass data between the two). - Handling authentication and state management across both frameworks. Integration between Frontend (Blazor/Angular) and Backend (ASP.NET Core): No matter whether you're using Angular or Blazor for the frontend, integrating these with your backend API is key. We'll discuss: - Setting up HttpClient for making API calls from both Blazor and Angular - Working with SignalR to enable real-time features in both frontends - Managing authentication and authorization across both Angular and Blazor (JWT, OAuth) - Best practices for passing data and sharing state between the frontend and backend Scalable and Maintainable Web Apps: When building full-stack web applications, it's important to focus on scalability and maintainability. Here are some practices for achieving this: - Structuring your application code to separate concerns (e.g., services, components, repositories) - Utilizing Dependency Injection for flexible and testable code - Modularizing your codebase for easier updates and maintenance - Using Lazy Loading for Angular and Blazor components to improve performance - Leveraging Caching strategies to enhance response times Testing and Continuous Deployment: For any modern application, testing and deployment are crucial. We’ll discuss: - Unit and integration testing in ASP.NET Core, Blazor, and Angular - Automated end-to-end testing (e.g., with Cypress for Angular, bUnit for Blazor) - Continuous Integration/Continuous Deployment (CI/CD) strategies for seamless deployment to cloud platforms like Azure or AWS When to Choose Angular, Blazor, or Both: It’s essential and interesting to know when to use each of these frameworks depending on your project’s needs. Some scenarios we’ll explore: - When to go for Blazor for a unified C# experience in both frontend and backend - Why you might opt for Angular when building highly interactive, feature-rich web applications - Hybrid approaches where you can use Blazor and Angular together for a robust full-stack solution SO: Combining ASP.NET Core, Blazor, and Angular allows developers to choose the right tool for the right job, creating flexible, scalable, and maintainable web applications. Whether you’re leveraging Blazor for its deep integration with .NET or Angular for its powerful frontend capabilities, these technologies offer a powerful suite of tools to build modern web applications.
