NullReferenceException with EF6 on Mono 3.0.3 - entity-framework

I am trying to migrate existing Entity Framework project to Mono and found a strange bug: when request being executed and EF loads model schema it throws under Mono despite that under .Net with EF6 Alpha 2 it works. An exception is following:

I guess it cannot load metadata or something like that, at least deapest lines looks like known behaviour of XmlDocument and XmlSchema when they do not check that input stream is null. I tried to use metadata files instead of embedded resources, but it did not help.
I will try to digg into sources, but it would be really helpful if someone already have idea what is going on.


You are running quite unusual configuration, EF compiled by Mono and System.XML from .NET Framework. This itself should work if System.XML can deal with the location of your schema but it's not common configuration.
I'd check how is the schema embedded into your assembly and whether is using same namespace.

Getting error "Could not load file or assembly 'System.Windows.Forms" at 'Import-Module "AzureAD" line in PS script

I am trying to deploy a simple powershell function app that contains the following commands:
Import-Module D:\home\site\wwwroot\HttpTrigger1\AzureAD\AzureAD.psd1
Connect-AzureAD -TenantId $tenantId -Credential $Credential
AzureAD module files have already been copied from local repository "C:\Program Files\WindowsPowerShell\Modules\AzureAD" to "D:\home\site\wwwroot\HttpTrigger1\AzureAD" using KUDU.

In PowerShell 7, the AzureAD module needs to be explicitly imported with the -UseWindowsPowershell switch, so that it is loaded into a separate Windows PowerShell session:
Import-Module AzureAD -UseWindowsPowerShell
For more details and caveats, see https://github.com/Azure/azure-functions-powershell-worker/issues/544#issuecomment-702324803

I still get the same issue in the terminal of my Ubuntu 18.04.5 LTS with Visual Studio Code 1.53.2 and PSVersion 7.1.1

EF Core Include method not working

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.

SSRS2008 Report SOAP OutOfMemoryException in IE8

I have an MVC3 website that uses SOAP to run a reporting services report and this is then returned to the browser. The users have IE8 on their machines and all the reports run fine except for one particular report that is throwing an error. The report takes 3 parameters and returns a table with < 10 rows. It only throws the error in IE8 when the number of rows is > 0. If the number of rows = 0 then it will return the report with just the headings. The report runs fine in ReportManager and FireFox. I have searched the web and StackOverflow looking for an answer with no success. The problem is I am not 100% sure whether it is a SOAP or SSRS problem or even something else and was hoping for some guidance.

I have fixed this issue now and the problem was the date format of one of the parameters. Once i sorted this out the report ran fine in IE. Not sure why it would work in Firefox with the wrong format.

Error "Failed to set database initializer of type MyNamespace.MyCustomInitializer, MyAssembly" could not load MyContext type

I'm creating a web app using .NET4.5 with Entity Framework 6 alpha3 that uses a new SQL Compact database. The database does not yet exist.
I have the following code in a web form:
public IQueryable<Job> listJobs_GetData()
{
var db = new JournalistContext();
IQueryable<Job> query = db.Jobs.Where(d => d.JobStart > DateTime.Now)
.OrderBy(s => s.JobStart)
.Take(10);
return query;
}
where the JournalistContext derives from DbContext.
It creates the instance of JournalistContext ok, but when executing the next line, it throws the exception below.
I'm guessing as the database doesnt exist, it tries to call the initializer, but this fails.
System.InvalidOperationException was unhandled by user code
HResult=-2146233079
Message=Failed to set database initializer of type 'TSJ.Models.MyCustomInitializer, TSJ' for DbContext type 'TSJ.JournalistContext, TSJ' specified in the application configuration. See inner exception for details.

As described here http://msdn.microsoft.com/en-us/data/jj556606 I have created a custom database initializer, which presently is a blank class:
internal sealed class MyCustomInitializer : MigrateDatabaseToLatestVersion<JournalistContext, TSJ.Migrations.Configuration>
{
}
public class JournalistContext : DbContext
{
public JournalistContext() : base("TSJ")
{
}
...
My web.config file references this initializer as follows:
<entityFramework>
<defaultConnectionFactory type="System.Data.Entity.Infrastructure.SqlCeConnectionFactory, EntityFramework">
<parameters>
<parameter value="System.Data.SqlServerCe.4.0" />
</parameters>
</defaultConnectionFactory>
<contexts>
<context type="TSJ.JournalistContext, TSJ">
<databaseInitializer type="TSJ.Models.MyCustomInitializer, TSJ" />
</context>
</contexts>
<providers>
<provider invariantName="System.Data.SqlServerCe.4.0" type="System.Data.Entity.SqlServerCompact.SqlCeProviderServices, EntityFramework.SqlServerCompact, Version=6.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089" />
</providers>
</entityFramework>
I'm stumped! Any ideas?
Another thing I've noticed: these lines have appeared in my web.config file. I'm not sure how they were added, or why.
<system.data>
<DbProviderFactories>
<remove invariant="System.Data.SqlServerCe.4.0" />
<add name="Microsoft SQL Server Compact Data Provider 4.0" invariant="System.Data.SqlServerCe.4.0" description=".NET Framework Data Provider for Microsoft SQL Server Compact" type="System.Data.SqlServerCe.SqlCeProviderFactory, System.Data.SqlServerCe, Version=4.0.0.0, Culture=neutral, PublicKeyToken=89845dcd8080cc91" />
</DbProviderFactories>
</system.data>
many thanks, Mark.

My guess is that your initializer class is internal. In my project I was loading it from another assembly and it could not see it. Once I changed to public it worked like magic.
I assume that it may be true even if you have everything in the same assembly.

My problem was related to my connection string.
Man, after trying the following links, I had no success. I was trying to connect to my SQLEXPRESS instance. I tried:
error loading database initializer with EF6
Reset Entity-Framework Migrations
Try this instead - this finally worked for me. Replace the data source with your SqlExpress/SqlServer instance if you aren't using localdb.
Enable-Migrations -ConnectionString "Data Source=.\SQLEXPRESS;Initial Catalog=[your database name];User Id=[your user name];Password=[your password];Integrated Security=SSPI;" -ConnectionProviderName "System.Data.SqlClient" -Force -Verbose
Add-Migration -Name "Initial" -ConnectionString "Data Source=.\SQLEXPRESS;Initial Catalog=[your database name];User Id=[your user name];Password=[your password];Integrated Security=SSPI;" -ConnectionProviderName "System.Data.SqlClient" -Force -Verbose
Update-Database -Force -ConnectionString "Data Source=.\SQLEXPRESS;Initial Catalog=[your database name];User Id=[your user name];Password=[your password];Integrated Security=SSPI;" -ConnectionProviderName "System.Data.SqlClient" -Verbose
Feel free to comment and I can continue trying to assist if you're still having this problem.
This was the resource I finally found that helped me understand a lot about what I'm doing.

Any help fixing this error?
Thanks

Why are you still using the CTP? The release has been out for quite some time. Upgrade, then see if your problem persists. It may be a fixed problem.

The stack trace points out that there is a problem with your connection string.
Fix your connection string, and the problem should dissapear.
