I have written a simple query which was working when I was using .net core 2.1 (I have used Z.EntityFramework.Plus.EFCore)
int cnt = adminDb.Role.Where(c => c.RoleId == roleId).Delete();
After upgrading to .net core 3.1 I am getting the error below.
Could not load type 'Microsoft.EntityFrameworkCore.Query.RelationalQueryContextFactory' from assembly 'Microsoft.EntityFrameworkCore.Relational, Version=3.1.0.0, Culture=neutral, PublicKeyToken=adb9793829ddae60'.

I am receiving this error and I'm not sure what it means?

I'm using R2DBC in my project. After upgrading to Spring Boot from 2.5.* to 2.6.1 my query:
#Query("SELECT EXISTS(SELECT 1 FROM some_link links WHERE links.data_id = $1 AND links.some_id != links.source_id)")
fun existsByDataIdAndLocked(dataId: UUID): Mono<Boolean>
Throws an exception:

Once I change $1 in the query to :dataId then it works.
Why is that? As per documentation, both are valid.
I have the below issue connecting to Mongo Atlas when I set android:targetSDKVersion="28" in my android manifest.

If I remove the android:targetSDKVersion="28", the app connects without the issue but google play requires that I set the targetVersion before I can upload to play store.
I am using MongoDB Driver 2.91
Can you please help with possibly the solution.
Thanks.
I found out that from Android 8 (Oreo), access to net.dns has been removed. I was connecting to the server with SRV lookup according to the connection string from MongoDB 2.9 Driver. The DNSClient was Performing a DNS lookup on the domain name on the connection string. The below issue from DNSClient.net library shows more.
https://github.com/MichaCo/DnsClient.NET/issues/17
However, I had to do a custom implementation to get DNS Servers using the below code:
public List<IPEndPoint> GetDnsServers()
{
var context = Android.App.Application.Context;
List<IPEndPoint> endPoints = new List<IPEndPoint>();
ConnectivityManager connectivityManager =
(ConnectivityManager)context.GetSystemService(MainActivity.ConnectivityService);
Network activeConnection = connectivityManager.ActiveNetwork;
var linkProperties = connectivityManager.GetLinkProperties(activeConnection);
foreach (InetAddress currentAddress in linkProperties.DnsServers)
{
IPEndPoint endPoint = new IPEndPoint(IPAddress.Parse(currentAddress.HostAddress), 53);
endPoints.Add(endPoint);
}
return endPoints;
}
The issue is gone.
I recently updated to asp.net core 2.0. Since upgrading all my Linq queries using Include Method are failing, it is not translated properly to SQL.
For instance this:
var entities = helpTopicRepository.Entities.Include(x => x.HelpArticles).FirstOrDefault(t => topicIds.Any(a => a == t.Id));
is translated to:
SELECT x.HelpArticles.ART_ID,
x.HelpArticles.AVAILABLE,
x.HelpArticles.CONTENT,
x.HelpArticles.DISPLAYORDER,
x.HelpArticles.HELPFULNO,
x.HelpArticles.HELPFULYES,
x.HelpArticles.KEYWORDS,
x.HelpArticles.TITLE,
x.HelpArticles.TOPICID
FROM HELPARTICLE x.HelpArticles
which is results in the following error:

I'm using Devart dotconnect to connect to Oracle database.
Is due to your statement:
var entities = helpTopicRepository.Entities.Include(x => x.HelpArticles).FirstOrDefault(t => topicIds.Any(a => a == t.Id));
Assuming that topicIds is a list, here is a fix:
var entities = helpTopicRepository.Entities
.Include(x => x.HelpArticles)
.Where(t => topicIds.Contains(t.Id))
.FirstOrDefault();
The bug with using multiple .Include() in EF Core 2 is fixed. Look forward to the next public build of dotConnect for Oracle.
I am following this article/tutorial on how to make a generic repository for ASP.Net Core at:
http://www.c-sharpcorner.com/article/generic-repository-pattern-in-asp-net-core/
When I download the code I am able to run the migrations and the project runs and works.
But when I follow the directions and try to build from scratch, then when I get to the point where I have to run the migrations:
Add-migration MyFirstMigration
I get this error:
C:\Tutorials\ASP.Net\Core\GenericRepository\FromScratch\GenericReposotory\GR.Web\project.json(20,43): warning NU1012: Dependency conflict. Microsoft.EntityFrameworkCore 1.1.0 expected Microsoft.Extensions.Logging >= 1.1.0 but received 1.0.0 No parameterless constructor was found on 'ApplicationContext'. Either add a parameterless constructor to 'ApplicationContext' or add an implementation of 'IDbContextFactory' in the same assembly as 'ApplicationContext'.
The tutorial had the model and repo defined in a class library including this:
namespace GR.Data
{
public class ApplicationContext : DbContext
{
public ApplicationContext(DbContextOptions<ApplicationContext> options)
: base(options) { }
protected override void OnModelCreating(ModelBuilder modelBuilder){
base.OnModelCreating(modelBuilder);
new AuthorMap(modelBuilder.Entity<Author>());
new BookMap(modelBuilder.Entity<Book>());
}
}
}
The options are passed in from StartUp.cs in the Web Project like this:
public void ConfigureServices(IServiceCollection services)
{
// Add framework services.
services.AddApplicationInsightsTelemetry(Configuration);
services.AddMvc();
services.AddDbContext<ApplicationContext>(
options => options.UseSqlServer(Configuration.GetConnectionString("DefaultConnection")));
services.AddScoped(typeof(IRepository<>), typeof(Repository<>));
}
And it gets the connection string from appsettings.json in the Web Project: GR.Web.
In the Package Manager Console I have GR.Data selected as the default project and GR.Web set as the startup project. I get this error:
C:\Tutorials\ASP.Net\Core\GenericRepository\FromScratch\GenericReposotory\GR.Web\project.json(20,43): warning NU1012: Dependency conflict. Microsoft.EntityFrameworkCore 1.1.0 expected Microsoft.Extensions.Logging >= 1.1.0 but received 1.0.0 No parameterless constructor was found on 'ApplicationContext'. Either add a parameterless constructor to 'ApplicationContext' or add an implementation of 'IDbContextFactory' in the same assembly as 'ApplicationContext'.
How is the download working and how do I get mine to work.
so confused.
On top of it I had to fool around with it forever to get all the depenanceies on EF Core and Tools Preview on the right versions to get this far.
Is there a better article somewhere on how to do this?
I fixed:
"Microsoft.Extensions.Logging": "1.0.0",
to
"Microsoft.Extensions.Logging": "1.1.0",
and now I get this error:

In dependancies for the Web Project, GR.Web, I rolled back

to
"Microsoft.EntityFrameworkCore": "1.0.1"
and now it works.

You'll probably have to wait for the guys at Falafel to release a version that targets Sitefinity 8.1
