Reproduction of problem here: https://github.com/Arrow7000/SqlProviderTest
I'm fairly new to the .NET world so am having trouble wrapping my head around exactly what the problem is.
I've tried to use the SQL type provider directly in an F# .NET Core project, but had a bunch of problems getting it to work. From what I can tell that's due to incompatibilities between .net core and type providers.
So what I am trying instead is to have the SQL type provider code encapsulated in a .NET Standard project that I can reference from my main Core project.
I've managed to reproduce the problem in a minimal GitHub repo located here which demonstrates both that
the type provider is working in Visual Studio 2019 with IntelliSense, but
despite this I still get a build error when I try to start the Main project
The build error is
Unable to find the file 'C:\projects\SqlProviderTest\SQLStuff\bin\Debug\netstandard2.0\SQLStuff.dll' in any of
C:\Program Files\dotnet\sdk\NuGetFallbackFolder\microsoft.netcore.app\2.2.0\ref\netcoreapp2.2
C:\projects\SqlProviderTest\Main
C:\Users\Aron\.nuget\packages\fsharp.core\4.6.2\lib\netstandard1.6
Why isn't the project reference simply working as expected? I've tried adding <Private>True</Private> to the project reference but that didn't make any difference
P.S. in case it matters, I'm developing on Windows but the app gets deployed on a Docker container.
I am starting a new ASP.NET 5 Preview template to play with client side development.
I have a database ( MS SQL ) that I want to access using the Web API and Entity Framework.
In my Models folder I do like I am used to do, add a new item and I want to add the ADO.NET Entity Data Model but it isn't there.
What am I missing here?
UPDATE
This is the only thing I see when I try to add a new item to the project.
Client side and server side.
After a lot of research, I found out that there are some compatibility issues where come from the recent Microsoft migration to open source world (since Asp.net5) that I obtained from Data Points - The EF6, EF7 and ASP.NET 5 Soup MSDN Article. Read the full article please.
So if you wanna have both EF6 and Asp.net5, consider the article tips. And if you don't persist in using Asp.net5, simply use Asp.net4.5 (following image) which have Ado.net Data Model in Add New Item dialog (I tested its availability with my Visual Studio Enterprise).
May sound stupid, but since I got caught with this, it might be someone else's issue too...
In VS 2015, there are 2 project templates called Class Library... one being in Windows and one in the Web and having (package) suffix. Apparently, besides misleading name they have nothing to do with each other and the second one clearly is not made to support EF models... Make sure you have created a proper project type or open a working solution made with different VS version.

Also this might help. I have it already installed, so not sure if it affects my configuration or not (shouldnt as EF tools are supposed to be shipped already with VS 2015):

Right click on project
Choose Add and then New Item (or Simply press Ctrl+Shift+A)
You will see a Data section which you can find what you are looking for

Missing ADO.NET entity data model template from visual studio 2012 professional
Create New MVC Project using VS2015
Right-Click on Model folder.
Choose Add and then Select Class from the list.
Now select ADO.Net Entity Data Model... and go for your selection.
ADO.NET Entity Data Model missing Visual Studio 2017 Community
How to enable:
Open Visual Studio Installer -> Individual Components -> SDK's, libraries, and frameworks -> Enable EntityFramework 6 tools-> Modify
Now, Add item in your project -> Data -> ADO.NET Entity Data Model.
Visual Studio Installer
Note: While Creating project don't select class Library(.NET Standard) Choose Class Library (.NET Framework)
I solved the same problem by following these:
While Creating project don't select class Library(.NET Standard)
Choose Class Library (.NET Framework)
Choose ASP.NET Web Application (.NET Framework)
Go to Tools -> Get Tools and features. Select Individual components tab and check Entity Framework 6 tools under SDK's, libraries, and framework section
Remember you can't make an ADO.net Entity Data Model with an interface with .NET Core, its only possible with .NET Framework.
The hosting provider for one of the web sites I manage has forced us to only be able to modify the site as a web project instead of as a web application. When it was initially a web application it was working fine, but after converting to a web site project I had many issues involving missing namespaces and references and was able to resolve them by placing all of my libraries inside of the top-level App_Code folder of the web site. I have one last issue with my linq-to-sql class - in Visual Studio the class is recognized now that it's in the top level App_Code folder, but when I call a page which references it I get the following error:
The type or namespace name 'LIFH_IntakesDataContext' could not be found (are you missing a using directive or an assembly reference?)
Initially there was no namespace whatsoever, but in my attempts to fix this I addded a "LIHS" namespace and placed the Data Context within that:
Here are the references for the site:
And here is the Build configuration:
And, here is my directory structure (Linq-to-SQL class is referenced in the circled "reports.aspx" page):
Code in reports.aspx:
Both the master page and the reports page are both in the LIHS namespace.
I am developing on Visual Studio 2012 and the application pool is set to .NET 2.0. The hosting provider does not allow anything above 2.0.
I have researched and found many references to my issue but most of them solve the problem by converting to a web application, which I cannot do, or by changing the target framework or by using a namespace, which I have done, but to no avail. I would appreciate any insight on this.
Pay Attention: Linq is only available in .Net 3.5 and later
If you are using .net 2.0 it wont work.
You can see it in your screenshot.
Hope it helps.

I am trying to create STS MVC web application in VS2012 and VS2013, but STS web template is not available in template gallery. Is there a way that I can download STS web app template in VS2012 and Vs2013 ?
One more query, We have Identity and Access tool in VS2012 but there is nothing like this in VS2013.
How I can install Identity and Access tool in VS2013 ?
Please help me.
If you read the Q and A for the Identity and Access Tool extension for VS 2012, you will see a post from a member of the team who indicates that it will not be ported to VS 2013. They have added support for claims based authentication directly into the ASP.NET project creation template.
In the post, they admit that they are not 100% equivalent, so they use VS2012 and VS2013 side by side until they achieve parity.

I added a project reference of my Business Logic project to my console application. I can reference the project and its classes in the code of my console application. Weirdly, when I build the project, the build fails and the classes which referenced says Type is not defined.Has anybody come across an issue like this?
You have to import name space in your console application class where you are trying to use the business logic application class.
I have selected the incorrect target framework .net framework client profile 4.0 where it should be .net framework 4. Issue rectified and now I can build the project.
