No suitable constructor was found for entity type 'CollectionEntry'
Getting the following System.InvalidOperationException exception. Attempting to convert a large EF6 solution to EF Core.
No suitable constructor was found for entity type 'CollectionEntry'. The following constructors had parameters that could not be bound to properties of the entity type:
Cannot bind 'internalEntry', 'name' in 'CollectionEntry(InternalEntityEntry internalEntry, string name)'
Cannot bind 'internalEntry', 'navigationBase' in 'CollectionEntry(InternalEntityEntry internalEntry, INavigationBase navigationBase)'
Note that only mapped properties can be bound to constructor parameters. Navigations to related entities, including references to owned types, cannot be bound.

Can invite you to the repo when this has been assigned to someone.
Include provider and version information
EF Core version: 8.0.3 Microsoft.EntityFrameworkCore.SqlServer Target framework: .NET 8.0 Operating system: Win 11 IDE: Visual Studio 2022 17.9.6
@RDoser Your projects are pulling .NET Framework assemblies into a .NET Core app. This is not supported.
@ajcvickers Thanks. So I think you are meaning the TreeViewHelper and WPFControls projects? I just upgraded those to .Net 8.0 and tried again but still getting the same error. Or did you mean something else? I pushed these changes to the repo.
@RDoser I will take another look when I get a chance. The first thing I do when looking at a repro is see if the project includes anything unsupported. As soon as I saw that it did, I stopped looking. Note that a good minimal repro is one .cs file, and I did notice that there is considerably more code than that. Have you removed everything not necessary to reproduce the bug you are reporting?
@ajcvickers Thank you. This is related to converting a large EF6 DB first solution with a WPF front end to EF Core. The repo I shared removes 99% of the WPF stuff. The HCAEntitiesCore project has just the raw data objects and can be run separately as a console application. It runs with no errors. The HCAEntitiesPartials adds the business logic to the data objects using partial classes and that is where the error comes in. I guess I could try removing one partial at a time (there are over 200) and see what happens but I was hoping that you guys had a quicker way to pinpoint the error. If I have time I will start that process while I wait for you to find time.
I guess I could try removing one partial at a time (there are over 200) and see what happens
Maybe try binary search? Like remove half (say 100 partials) and see if it still repros. If it does, then remove 50 more, etc…
@RDoser Your project still contains these references:
<ItemGroup>
<Reference Include="System.Deployment">
<HintPath>..\..\..\..\..\..\..\..\Program Files (x86)\Reference Assemblies\Microsoft\Framework\.NETFramework\v4.8\System.Deployment.dll</HintPath>
</Reference>
</ItemGroup>
As far as I know, as soon as you reference .NET Framework DLLs from .NET Core, then all bets are off with regard to correct resolution of members.
@ajcvickers Thank you! I removed that reference and fixed any related code lines but still get the error. I noticed that I also reference an excel interop assembly. Is that also a problem? Is excel interop not allowed in .Net Core?

@ajcvickers Thanks for your help so far. After eliminating a minor branch of object partials the error was replaced by a more relatable complaint regarding properties/relationships that were not intended to be persisted to the database. There are are thousands of these so I was faced with either tons of [NotMapped] tags or disabling the "by convention" part of EF Core. Since this is a DB first EF6 project with an existing EDMX file I have chosen the later approach for now and am in the process of converting the EDMX into Fluent API code. Too bad there isn't an existing tool to do that automatically as I am sure to not be the only person in need of it due to Microsoft abandoning EF6. Just wanted to let you know that I'm moving forward and not stuck. Thanks for your help.
@RDoser In our experience, starting by reverse engineering from the existing database or dacpack is how most people approach moving an EF6 database to EF Core. @ErikEJ I'm curious if you still see a lot of people wanting to start from an EDMX?
@ajcvickers Extremely rarerly, and they usually fail badly in the attempt to do so.
@ErikEJ @ajcvickers Interesting. I don't know what failing badly would look like (exploding computer?). I do know that everything needed for a fluent API construct resides in my EDMX including property mappings, TPH discriminators, and many navigational relationships that are not defined in the database. It just seems like a no-brainer to me to use it as a conversion starting point as it is essentially an XML version of the fluent API.
@ErikEJ @ajcvickers I'm continuing to work on this but I'm not sure why I'm hitting this new error:
System.InvalidOperationException
HResult=0x80131509
Message=The property 'Account.IsEntityInitialized' could not be mapped because it is of type 'bool', which is not a supported primitive type or a valid entity type. Either explicitly map this property, or ignore it using the '[NotMapped]' attribute or by using 'EntityTypeBuilder.Ignore' in 'OnModelCreating'.

The IsEntityInitialized property is inherited from the ignored base class, EntityBase. Shouldn't the following code have prevented this? Is there a step I am missing?
protected override void ConfigureConventions(ModelConfigurationBuilder configurationBuilder)
{
...
configurationBuilder.Conventions.Remove(typeof(PropertyDiscoveryConvention));
configurationBuilder.Conventions.Remove(typeof(PropertyOverridesConvention));
...
}
protected override void OnModelCreating(ModelBuilder modelBuilder)
{
modelBuilder.Ignore<EntityBase>();
...
}
I was looking at this comment (https://github.com/dotnet/efcore/issues/14405#issuecomment-454207922) but it seems a little out of date as I can't find PropertyMappingValidationConvention anywhere in the documentation.
Also, I started looking at the code for ModelValidator.ValidatePropertyMapping() which appears to use IConventionTypeBase.GetDeclaredProperties() to see if there are unmapped properties. The docs for this method (https://learn.microsoft.com/en-us/dotnet/api/microsoft.entityframeworkcore.metadata.iconventiontypebase.getdeclaredproperties?view=efcore-8.0#remarks) state that it "does not return properties declared on base types," which makes this even more of a head scratcher since that appears to be NOT the case?
As always, thank you so much for your time and expertise.
@ErikEJ @ajcvickers Okay, so you guys really have provided no way to constrain EF Core from considering ALL read/write properties as things to be persisted to the database besides this anemic [NotMapped] attribute? Why isn't it an option to completely define my model using Fluent API so that your validation code ignores all properties not explicitly mapped? Essentially you are letting the tail wag the dog. My objects have thousands of non-persisted properties that allow them to do the things that make them useful. I shouldn't have to write [NotMapped] every time I add a new property.
Is there a way to designate a model that isn't IConventionModel? If there is, then it looks like that would skip the offending validation...
