Today I'm going to work on my side project that I haven't touched in weeks.
I want to utilize Angular 2 which means I'll need to learn TypeScript. I also want to use the new .Net Core and EF Core 1.0. Oh and I want to handle authentication using JWT!
Wow, that's gonna be a lot of effort to get things off the ground... maybe instead I'll use this time to learn some new concepts. Maybe watch this episode of Fun Fun Function, or maybe this video on writing Assembly code for an app on Raspberry Pi, that sounds cool!
Actually, you know I should really teach myself dependency injection and unit testing for once. I'm so behind the times.
Well, really I should finish this book on design patterns first. Ok, where did I leave off? Page 20 I think... ehh... maybe I'll just work on my side project.
Tomorrow... tomorrow, I'll work on my side project.9 -
.Net is masterrace.
C# gives me frequent orgasms.
Use SQL Server for DB, add to that parallel querying and NoSQL capabilities.
Incredible development speed with EF
Incredebly powerful web framework...check
AI and neural networks...check
App Development...Xeck
If you want to do some of that functional programming F# is the language for you.
And the best thing: .Net core runs on Linux too10 -
Our project at work goes live in 3 weeks.
The code base has no automated tests, breaks very often, has never had any level of manual testing
will not be releasing with any form of enforced roles or permissions in our first release now due to no time to enforce, however there is a whole admin api where you can literally change anything in our database including roles.
We also have teams in various countries all working separately on the same solution using microservices with shared nuget packages and they aren't using them properly.
Our pull requests are so big - as much as, 75 file changes - in our fe app that I can't keep up with it and I honestly have no idea if it even works or not due to no automated tests and no time to manually test.
We have no testing team, or qa team of any sort.
Every request into the system has to hit a minimum of 3 different databases via 3 different microservices so 1 request = 4 requests with the load on the servers.
We don't use any file streams so everything is just shoved in the buffer on the server.
Most of the people working on the angular apps cba to learn angular, no one across 2 teams cba to learn git. We use git so they constantly face problems. The guy in charge has 0 experience in angular but makes me do things how he wants architecturally so half the patterns make no sense.
No one looks at the pull requests, they just click approve so they may as well push directly to master.
Unfinished work gets put in for pull request so we don't know if the app is in a release state since aall teams are working independently, but on the same code base.
I sat down and tested the app myself for an hour and found 25 fe only issues, and 5 breaking cross browser issues.
Most of our databases are not normalised. Most of our databases make no sense. 99% of our tables have no indexing since there is no expertise with free time to do it.
No one there understands css properly. Or javascript.
Our. Net core microservices all directly use ef in the controller actions so there is no shared code there.
Our customer facing fe app is not dry because no tests so it was decided it was better this way.
Management has no idea on code state, it seems team lead is lieing to them about things like having any level of tests.
Management hire devs that claim to be experts but then it turns out they have basically no knowledge of what they were hired to do, even don't know what json is or the framework or language they are hired for, but we just leave them to get on with it and again make prs too big to review.
Honestly I have no hope that this will go well now but I am morbidly curious to watch. I've never seen anything like the train wreck that we are about to get experience.5 -

I am on vacation from my full time job this week. I wanted to use this week to write a PoC for a potential customer of my side business. really interesting project for me.
potential customer is a window and door manufacturer and needs an application to manage their racks.
their ERP system already has a simple rack management but it is only useable in house.
they want the drivers to be able to scan racks they deliver to a customer with a native app and they want to have a webapp for the customers to see racks that are assigned to them as well as reporting a rack ready for collection. And that all needs to be in sync with their local ERP system.
as i am a .net guy i decided to go with the abp framework (because it got recommended to me) and xamarin for the native app part (because i have experience in this).
i have now spent 4 days implementing this and it has been so rewarding. the framework is so powerful and it's template saved me endless hours.
i even wrote a very basic connector service which synchronizes data between my app and the clients ERP system. Just one way until now because of time issue, but i learned to scaffold an ef core with db first. It is noticable that the ERP system is 2-tiered - meaning the clients directly talk to the db.
Tomorrow i will implement the xamarin client.
4 days just coding what i want to. choosi g my own velocity and making my own priorities without any interruptions or discussions and a bunch of new things to learn.
Probably wasted half a day because of stupidy (implemented some bugs) but fixing and learning is part of the journey and i lime that part, too.
i am so relaxed right now 😁 just wanted to share this without a real reason :P3 -
Hi guys, I’m that good guy MIS who knows a little bit python and got “promoted” to write a warehouse management system in C#, which I have never use it before.
Just now I submit my first pull request to DevOps and got accepted.
Just a small EF core and barcode generators stuff but I’m so glad I made some progress 😬3 -
So we’ve taken over from a project team that disbanded... read: “cut their contracts because fuck this, I can earn more working for better people”.
Me and one other guy have been tasked with saving this heap of shit.
Obviously the project guys left saying “it’s nearly done, just this one feature”. Because cut contracts are easier to deal with if “everything is almost done”.
We jump on and find that’s not the case at all... this thing, is a beast, a big old stats analysis program... so we’re like “cool, let’s see what’s going o...OH MY GOD”.
The “recalculation” function was core to this POS. The contractors had done it in C# through entity framework... it took 24 hours to run, over a reasonably small data set that was due to double every 2-5 years.
So... here’s the deal, it ran over night.... then failed. And no cunt had noticed. Entity framework “can’t commit because I’m muddled up as fuck, did you really just put the whole db in EF in memory to work with it?” Exception.
Que 6 months of me and my lead doing the job properly.
Anyway, the failure: I ended up in Hospital again with a Crohn’s flare up... about 5 months in.
Fuckall to do with all this nonsense I just wanted to tell a story. it was an interesting/fun project to fix and my lead was a legend... so happy days.
Similar story, different set of contracted devs... they’d been defining requirements with the business users using the term “Risk” which the business users knew as a group of risks.
The domain model had been written RiskGroup<>— -
Wasted two hours to end up finding out EF Core had a bug :\
Next time better blame Microsoft before blaming my code lol

Working on a project in college
we thought a messenger would be cool. (Language: C# )
We decided to use a microservice architecture, rabbitMQ, .Net Core and some frameworks like EF.
My project leader changed the whole project because he is convinced that we need bleeding edge technologies if we want to create a great product. He added over 15 frameworks like MassTransit which released 10 days ago (.Net Core support).
Now we have to put a lot of effort into learning how these frameworks work instead of implementing.
How would you handle this?4 -
Me: What if I use navigation props in EF Core, what might go wrong?
*tests API call*
*120 seconds later finally got result*
Me: I better undo my changes and stick with 2 seconds response time O_O -
I will never make a backend in C# ever again.
Just look at this bullshit:
official docks, PAGES long: https://learn.microsoft.com/en-us/...
confused devs running rampant: https://stackoverflow.com/questions...
absolute total GARBAGE
literally ANY other language or framework, you set an env file and you fuck off. of course microsoft has to make the most convoluted pile of shit horse shit fuck shit that confuses everyone. i shouldn't have to pray to the dev gods every time i spin off a staging or production build that my environment variables are set correctly

How would you handle this:
You generate an id
You chech the db if it is not taken
If it is taken you generate a new one and check again.
You then save the new item with the generated id.
How do you ensure that between the time you checked and the time you added the item some other call did not try to also add an item with the same id.

Yesterday I wasted 2 hours because a bug in EF Core (https://devrant.com/rants/2323794/...)
Today I wasted another 2 hours because of a bug in Android Studio 3.5.2, which had a report only available in AS 3.6-alpha channel.
Dev life is wonderful huh?

EF/asp.net core issue..
I've got a many to many relationship between idea and hashtag.
Currently i can POST an new idea with new hashtags just fine, but if i then POST a new idea, with the same hashtags, it tries to insert the hashtag again into hashtags on sql server, and fails since the hashtags should be unique...
What i expect of it is to just update junction table using the already created hashtag from first POST and create the new idea 😅question entityframeworkcore entity framework asp.net exam asp.net core project exams c# confused help21 -

EntityFramework Core
GraphQl.Net
EntityFramework. GraphQl.Net
Blazor client side (Which reuses classes from EntityFramework project via nuget)
That’s it. I don’t care what anyone thinks. That stack is amazing.
(A small Bravo for this project too : https://github.com/SimonCropp/... )
0 JavaScript
Everything can be unit tested.
Changing 1 class in EF flows down directly to front end.
It’s fucking awesome. And a big : “NEVER AGAIN in my life” to JavaScript4 -
So I’m not having too much trouble with my project. Does that mean I’m doing something too easy or have I actually just absorbed the knowledge I’ve been reading?
I’ve never actually used EF Core before and I thought this would be harder, and more time consuming.2 -
How long is the "longest" EF core context you've seen ?
Without any additional methods.
Just DbSets and OnModelCreating.
Mine is 1338 code lines right now6 -
I hate waiting on a preview of an SDK from Microsoft that should have the support for the feature in the first place. I should be able to query a view without needing a primary key. I am tired of making workarounds. Come on EF Core 2.1 preview! You’re killing me! Back to ADO.NET for now.

Have you used Postgresql with EF Core code first? My migrations don't run. It says in correct syntax near GENERATE. I don't know if this is a bug or I'm doing something stupid5

What alternative do you use for EF Migrations?
We are in current stage that it's slowing our build time for 30 seconds, and each month we need to clean them and do the same for the whole pipeline (dev, qa, prod)...
It's way uncomfortable to work with it since we have stored procedures and ef doesn't track them...
What alternative did you chose to use?1 -
I'm trying out some stuff I read. I have rich domain models with private fields. In order to create EF core entities my domain models create snapshots with public properties.
So 3 models - domain, snapshot, entity.
Now I am thinking about introducing a fourth for the API.
This seems mental and that I have misunderstood something. Automapper might help clean this up.
