In VS 2022 and XAF solution, if I configure for .net 6 then the model editor will no longer opens. I get this "Could not find the ModuleBase descendant to build the Application Model."
I can still build the solution.
If the same but I use .net 5 then it works just fine.
Ther is a workaround on this post
Model Editor does not work with .NET 6 projects

I noticed that this type of project does not support files edmx.
What is the right way to develop a project in Asp.net 5 MVC 6 using Entity Framwork 7?
Currently(as of EF 7, RC1) Database First support is still in development. More info on roadmap page here and on EF Design meeting notes here.
Since this is in development there are ways to try this and more info and tutorial on commands can be found at official documentation page here.
The problem is that EF7 kill EDMX. You now have Code First-style POCOs tied to an existing database, without an EDMX file in sight. The EF Power Tools Visual Studio extension can be installed to generate all of this directly from existing database.EF Power Tools Visual Studio extension actually doesn't support vs 2015
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.
In Visual Studio 2015 Preview, I see the following vNext templates in the "New Project" window:
I am under the impression that I should also see an entry for "ASP.NET 5 Empty Web Application" or something similar, but I see no such thing. Those two entries are the only "vNext" designated entries that I have installed.
Is there an additional binary I need to install in order to enable this type of project to appear? Or do I need to examine my VS 2015 Preview installation?
Note: I do have an entry for "ASP.NET Web Application", which takes me through the setup with the unified architecture but does not appear to include a project.json file or things that I'm associating with ASP.NET 5 development.
Update: Per this article regarding 2013 I also tried to run devenv.exe /installvstemplates, but that didn't work either. To clarify, I don't see any new web template, which the screenshot below illustrates as well:
I was having the same problem, except that unlike the accepted answer suggests, the ASP.NET Web Application was not on the list of templates at all.
I was able to get it to show up after following the instructions from this article.
From Visual Studio 2015: Tools -> Extensions and Updates
Select Online then click Visual Studio Gallery
Search for ASP.NET Project Templates and download the first result.
Go through installation process, relaunch Visual Studio, and Web Application should now be an option!
Alternately, you can download the templates directly here.
I believe this download actually is meant to install some other templates that I wasn't interested in, but installing them must have also installed the base template in the process. Either way, it worked for me.
Visual Studio Ultimate 2015 Preview contains everything you need to create an ASP.NET 5 (vNext) web application. One additional generic option should be available that's not depicted in your question:
It's not entirely clear at this point, but choosing the generic web application option will present a few ASP.NET 5 (vNext) options that you're seeking in the following dialog:
In Visual Studio 2015 Preview Microsoft has renamed ASP.NET vNext to ASP.NET 5
If you open http://www.asp.net/vnext, in every article vNext is metioned as ASP.NET 5
In following Sam's Suggestion, I noticed that there were Updates Pending. One of these updates included the missing ASP.NET 5 templates.
Tools > Extensions & Updates > Updates > Visual Studio Gallery
Once updated & Installed, the Web Application was then available as described in the tutorial.
The new update released this week has renamed ASP.NET 5 into a new framework which they are now calling ASP.NET Core. More information can be found in this article https://blogs.msdn.microsoft.com/webdev/2016/05/16/announcing-asp-net-core-rc2/
VS 2015 Preview is going under ASP.net Core web application. If you cant see that one under templates you may go to this site and download .NET Core 1.0 for Visual Studio then install.
In my case the problem was in the Microsoft .NET Core 1.0.1 VS 2015 Tooling Preview 2 corrupted installation.
It was performed:
install the ASP.NET Project Templates following answer from this post - NO RESULT
reinstalling Microsoft Web Developer Tools from the identical SO post - NO RESULT
fresh install the IDE using TotalUninstaller tool - NO RESULT
repair the Microsoft .NET Core 1.0.1 (see the sketch below) - SOLVED
Only repair .NET Core 1.0.1 finally solved the problem!
For that you have to download the .net core cross platform development, below steps you will refer
open VISUAL Studio installer
click the option in the list click modify
below image you can refer it
once complete installation,now you have the option for asp.net core web application
I have a quick question concerning creating an web forms application with visual 2013 express. I'm working on older servers (Windows 2003) which cannot handle anything greater than .NET 4.
When I go to create my application with visual studio 2013 I go to the Visual Studio 2012 tab, where MVC 4 is listed and choose the web forms application there. What I've learned though, is that it automatically sets the framework to 4.5 still, so I have to change it to 4. In doing so, the NuGet packages get messed up and I have to reinstall them all. I discovered after reinstalling them all it's still messed up and I'm getting build errors. I assumed because I choose to use an older version of webforms, it would automatically set my framework up for me as well. Doing a little troubleshooting I discovered that even when you choose to create a MVC 4 application it still sets the framework to 4.5 and messes everything up when you try to change it.
I'm thinking about just downloading an older version of visual but I don't have admin rights to my computer and that is a pain. Any insight?
I'm painfully new to this material, so everything in layman's terms is appreciated!
when you select MVC 4 Web Application, or any of the other templates, there is a drop down at the top that allows you to select which Framework you would like to use. I'm using professional, it may be different in express.

I have a large solution with a number of projects in it.
I recently upgraded to VS 2012 and changed the Target Framework of all the projects to .NET Framework 4.5.
I now cannot see any of my Custom Activities in the Toolbox.
My Custom Activities are in the same Project as the Flowchart activity I am building so should show up automatically.
If I use Choose Items I can load the Custom Activities into a Toolbar folder by pointing at the .dll. I don't want to do that because it ties me to the debug or release dll.
I've tried a few things from the web but not found a solution.
Any idea what I should do?
Make sure the custom activities project target platform is AnyCPU. If it is set to x64, VS will not be able to load it as VS is still x86.
I passed my code to Microsoft who tell me that this is a bug in VS 2012 and that it is solved in VS 2013
