Is there a tool for Entity Framework In Memory database (for unit testing purposes) for standard .NET Framework?
I know there is one for .NET Core that works great, but for this project I need for the standard.NET framework
Effort might be exactly what you're looking for.

I know EF Core is a complete rewrite from ground up. Wanted to know about the performance/memory footprint improvements made in EF Core compared to EF.
Am having a .net core 3.1 web-api, I will have to use Postgresql. Wanted to know whether using an ORM(like EF Core) is a good solution?
Or is there any other better data access technology(no ORM or dapper) which can be highly performant to access Postgresql in .net core 3.1 application?
I do not know if this is a valid answer as I am the author of this, but it is something that you may looking. Please have a look at RepoDB.
I have created a new application, using the SPA templare of .netcore, to this solution i want to add another project to handle the database connection(DAL).
When i am adding ASP.net core Web Application to this solution, i then want to add to id an ADO.net entityframework template, but in the data section, it dont appear:
So I end-up adding a class Library(.net framework)
and to it i can add an ADO.net Entity Data Model
So now in the solution, i have 2 projects, 1 is .net core 2.1 for the API's, models and views(by angular).
The second project is a .net framework 4.6.1, class library project.
My question is, is it suppose to be like that?
is it a good thing to mix different frameworks
Please see this article regarding what each framework is, and what each is specifically designed for.
https://learn.microsoft.com/en-us/dotnet/standard/frameworks
In a nutshell, your requirements drive which framework you choose.
I would recommend sticking with EF Core (just my personal opinion, take it or leave it) The EF Core method of database first is only recommended if you require a 1 time migration from a source database. Microsoft Doc
If you need to CONTINUE working with an entity model past the first migration, it would be in your best interest to use Entity Framework 6, on a .NET Framework library like you have. But that doesn't stop you from using EF Core as your OR/M, because you can indeed have .NET Core reference .NET Framework.
Is it possible to deploy / install Entity Framework Core 2.0 alongside traditional Entity Framework 6? Is it fully possible, or possible but with some hang-ups, or not possible? Is this documented somewhere? I think I've seen they said they designed it to be side-by-side, but I'm having a hard time fully confirming this. Thanks.
The official documentation says the following:
It is possible to use EF Core and EF6 in the same application. EF
Core and EF6 have the same type names that differ only by namespace,
so this may complicate code that attempts to use both EF Core and EF6
in the same code file.
If you are porting an existing application that has multiple EF
models, then you can selectively port some of them to EF Core, and
continue using EF6 for the others.
This means of course that you can install both EF6 and EF Core in the same project. I have done this in a few simple cases myself and it was working ok.
Can anyone share their experience and insights on upgrading from EF6 to EF7?
Was it straight forward? Did you discover any major benefits or drawbacks from this upgrade?
Thank you
Read this Side-by-side comparison between EF-6 and EF Core 1.0.
https://learn.microsoft.com/en-us/ef/efcore-and-ef6/features
if you need any feature which is still not done then use EF 6 because maybe you have to wait a long time.
My recommendation, if it is really not possible to use EF 6 because you have .NET Core on UWP etc, then use it, otherwise currently you can prefer to use EF 6 over EF Core this is also a recommendation from EF team you can find it on the Announcing Entity Framework Core 1.0.
When to use EF Core
We now have a Comparing EF Core and EF6.x section in our documentation. It includes guidance on when to use EF Core, feature comparisons, and information on porting to EF Core.
These are the types of applications we would recommend using EF Core for. For all other applications, you should consider using EF6.x.
New applications that do not require features that are not yet implemented in EF Core.
Applications that target .NET Core, such as Universal Windows Platform (UWP) and ASP.NET Core applications.

It seems from the MSDN overview that the only change to ADO.Net in .Net 4 is the addition of Entity Framework.
I'm working on refactoring some legacy database access to use ADO.Net and one of the things I'd like to document as project issues is any benefit from moving to .Net 4 from the .Net 3.5sp1 we're currently targeting (we have a WPF GUI - it's a pure desktop app).
There have been a lot of improvement on linq-to-SQL as well see here, and that was for beta2, don't know if more stuff made it in the Release:
