Polymorphic query handling in EF Core - Thoughts?

So I'm having to deal a lot with entity polymorphism and querying the db to avoid having to execute multiple separate queries. I'm not sure about best practices here, but i also have to eagerload certain nav props from the derived types. Anyone know a better way than this? ```cs private async Task<IReadOnlyList<CoreProduct>> GetCoreProducts(IEnumerable<IProductRequest> requests, int internalPropertyId) {...

How to show validation message for a nested object's property in a list in blazor

I have 2 models Customer and Contact. A customer can have 1 or more contacts. I'm using EditForm and Mudblazor with ObjectGraphDataAnnotations Validator and a custom validation component (taken from Microsoft Documentation). I'm using the custom validation component to validate the customer name is unique by checking the database (which works correctly) and I'm able to validate that the contactNames in the list of contact objects are unique but i'm unable to show the validation message for that particular field. I'm only able to see this validation message in the validation summary. I'm passing the validation message using a dictionary of field and its value. I've tried passing the field name as $"customer.Contacts[{index}].ContactName" (The relevant part of the code is under the 1st comment from the bottom in the AddCustomer.razor file) but it doesn't seem to work. For code and more details refer to https://github.com/MudBlazor/MudBlazor/discussions/8092...

I’d like it to be a system tray thing that toggles the gui on keypress. Should I do this with basic .NET C# in visual studio to make the gui and make it system t...

How to use Server Sent Events with HttpClient

I'm working with an API framework (https://docs.mistral.ai/api/#operation/createChatCompletion) in which you send a chat request. If you set the stream parameter to true:

tokens will be sent as data-only server-sent events as they become available, with the stream terminated by a data: [DONE] message. Otherwise, the server will hold the request open until the timeout or until completion, with the response containing the full result as JSON.

Forwarding domain emails without a mailbox

I have a few domain names on GoDaddy and they charge to have a mailbox, although I don't need the mailbox, I just need to forward the email to an existing gmail or outlook account. Here's a mockup of what I'm trying to do. I have full control of the DNS on all domains and I am able to add MX records, but how can I tell gmail or outlook that they should be receiving emails from these specific emails?...

How do I set environment variables for a MAUI Android app?

at work my team and I have been struggling with how to get values (versions, prod urls, etc.) we store within environment variables in our build pipeline. our process works fine for our web app, but our environment variables don't seem to exist when our MAUI Android build is running. we tried troubleshooting this in our local build as part of a group debug session, and i noticed that when i asked my teammate to call GetEnvironmentVariables from the immediate window, we got the same batch of variables back every time. our environment variable was nowhere to be seen, but when we ran our unit tests, the tests picked up the variable just fine....

best way to handle multiple codebases interacting with same db?

Hi everyone, I’m working on a “bank” project that has two codebases, the first is an ASP.NET based API that the website front end interacts with, and the second is an Azure Functions based service worker that is used to run scheduled tasks, such as interest payments. Both use EF Core to talk to the DB Essentially, I have the API ready to go, but it has several data validation checks when interacting with the database, such as source account has enough currency to cover the transaction etc. I’m not sure what would be the most scalable way to replicate that code to the Azure Function, so that if I make any changes to the model used or something, how can I make sure that the function’s code stays in sync without manually copying it across?...

Securing .NET Framework Applications Against SQL Injection: Unraveling Windows SSL Vulnerabilities

I have developed a .NET Framework 4.7.2 Windows application that utilizes a SQL Server database. In this application, I have employed the SQLClient package to establish connections to the database. The connection parameters include encryption, ensuring that queries in outbound traffic remain concealed from the Microsoft Network Monitor and Wireshark. However, a vulnerability was discovered when employing the Echo Mirage tool, enabling SQL injection or hooking into the .NET app process on Windows. This allowed for the viewing and alteration of queries using the tool. Through my analysis of the SQL injection tool's traffic log, I identified three types of hooked modules: Windows Socket, OpenSSL, and Windows SSL. When configuring Windows Sockets, I observed that the traffic protocol was TCP, and the queries were encrypted, providing a secure environment. However, configuring Windows SSL revealed a vulnerability. I could view and modify queries by injecting the process in Windows, and the protocol was displayed as "???" with source and destination set as 0.0.0.0....
