kandi X-RAY | dapper Summary
dapper is a simple lightweight desktop application auto-starter. It will read .desktop files in the autostart directories, all according to the FreeDesktop autostart specifications. You can define which desktop to start applications for (e.g. GNOME, XFCE, etc) in configuration file (~/.config/dapper.conf) or from command line. Note that autostarting desktop application is probably already taken care of if you do use a desktop environment/session manager.

QUESTION
I have trouble with creating one specific "dataset" from list of objects which I get via Dapper from database. So the thing is about daily attendancies in company, so user comes and click and goes out and click and we have one table row like this: sql table So I have a model class like this:
...ANSWER
Answered 2022-Apr-08 at 12:31You probably won't be able accomplish that with just LINQ. You should be able to loop over the items returned in the results that you just fetched, and do your logic there.
Implement a function like this, and call it after retrieving your results. You could even handle the database querying in this function too if you'd like, then just call the function and get back your list.

I am deploying an Azure Function called "Bridge" to Azure, targeting .NET 6. The project is referencing a class library called "DBLibrary" that I wrote, and that library is targeting .NET Standard 2.1. The Azure Function can be run locally on my PC without runtime errors.
When I publish the Azure Function to Azure, I see in Azure Portal a "Functions runtime error" which says:
Could not load file or assembly 'System.ComponentModel, Version=6.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a'. The system cannot find the file specified.
I do not target System.ComponentModel directly, and I don't see a nuget package version 6.0.0 for "System.ComponentModel" available from any nuget feed. Why is the Azure function looking for this version 6.0.0 of System.ComponentModel? If that version does exist, why can't the Azure Function find it?
Here are the relevant parts of the csproj for the "Bridge" Azure Function:

Answered 2022-Feb-25 at 10:33The .net standard you are using 2.1 but ,Microsoft.Azure.Functions.Extensions can be support upto .NET Standard 2.0
You should add the below package to your function app and deploy to Azure again.

I'm trying to figure out how to setup a login via Discord Oauth2 while using Dapper as my ORM.
Microsoft has a guide here that I have followed to setup all of my stores. I infact can call CreateAsync() method and a user gets created in my database, so I believe that side of things is completely setup.
My issues lie within external login. Below you will find what I have tried.

Answered 2022-Jan-29 at 17:34Firstly... We need to take a look at the implementation of the internal method GetExternalLoginInfoAsync inside SignInManager.cs and take note of all the conditions that could possibly lead to null being returned.

I have a busy ASP.NET 5 Core app (thousands of requests per second) that uses SQL Server. Recently we decided to try to switch some hot code paths to async database access and... the app didn't even start. I get this error:
The timeout period elapsed prior to obtaining a connection from the pool. This may have occurred because all pooled connections were in use and max pool size was reached.
And I see the number of threads in the thread pool growing to 40... 50... 100...
The code pattern we use is fairly simple:
...ANSWER
Answered 2021-Dec-11 at 12:54Well, after a bit of digging, investigating source codes and tons of reading, it appears that async is not always a good idea for DB calls.
As Stephen Cleary (the god of async who wrote many books about it) has nailed it - and it really clicked with me:
If your backend is a single SQL server database, and every single request hits that database, then there isn't a benefit from making your web service asynchronous.
So, yes, async helps you free up some threads, but the first thing these threads do is rush back to the database.
Also this:
The old-style common scenario was
client <-> API <-> DB,and in that architecture there's no need for asynchronous DB access
However if your database is a cluster or a cloud or some other "autoscaling" thing - than yes, async database access makes a lot of sense
Here's also an old archive.org article by RIck Anderson that I found useful: https://web.archive.org/web/20140212064150/http://blogs.msdn.com/b/rickandy/archive/2009/11/14/should-my-database-calls-be-asynchronous.aspx
QUESTION
I am trying out Dapper and I have stumbled upon this exception:
...ANSWER
Answered 2021-Sep-13 at 10:42I suspect the real problem here is that you are returning an open queryable, which means you're leaving the scope of the using block and disposing the connection that is still being used. The real problem here is an object disposed too soon, but it is manifesting in an unusual way.
Basically, you need to not dispose the connection until you're done with the data that needs the connection. A lazy way of doing this would be:

In netcore 5 C# I check at the start of the application if the database is on the latest version if not, depending on the version installed at the specific customer, it updates automagically (and does specific things per customer).

I'm using HotChocolate as my GraphQL server and Dapper to access the database in my project. Currently With each graphql query requesting "some" fields of an entity, the whole row is queried from database and this is wasting resources especially when querying lists of data.

Answered 2021-Jul-07 at 14:21Well, I managed it (honestly, I used it because of aggregation field feature), but via another package NReco.GraphQL - it takes exactly those fields that you set in the GraphQL query.
