I have been asked to update my Visual Studio with asp.net core. But the update told me I already have this component. However when I look in the list for New Project I can find nothing which includes the word CORE.
How do I work this out?
I'm not talking about a single Visual Studio Project or File. I'm talking about the whole program. I have to update the program.
You need to download Tooling Preview 2 to get the asp.net core templates. That is a bug in the visual studio 2015. Please follow the following steps to resolve this issue
This is what your add new project dialog will look like once you have .net core installed correctly. Were you able to resolve this?
Is it a console app or a web app? If you have a .xproj file in your Visual Studio project, then you have ASP.NET Core web application. Probably the same for an ASP.NET Core console application.

I have a huge enterprise asp.net application that perfectly builds and runs on servers. We've been using Visual Studio 2013 in our workflow. Now we want to migrate to newer IDEs. But if I build this application in Visual Studio 2017 I'll get this error.
Error BC40004 sub 'PreInit' conflicts with event 'PreInit' in the base class 'Page' and should be declared 'Shadows'.
I think it's a problem with VB compiler version (again vs2013 builds project). Do you have any idea how to fix this?
My solution contains 40+ projects. The main project is asp.net webforms app written in VB.net. Other projects are services and code libraries written in C#.
I tried to specify VB.net version in .vdproj manually. But it didn't solve my problem.
edit: Fine. Thank you all for your responses. I got that problem is about code and that visual studio analyzer has changed a lot in the last few years. I'll try to find out the reasons why this code have been working without exceptions.
BC40004 is a warning, this shouldn't prevent you to compile the solutions unless you set the Treat warnings as errors on the project's property under the tab compilation.
I am trying to follow this tutorial: https://learn.microsoft.com/en-us/aspnet/core/tutorials/razor-pages/razor-pages-start
However, when I get to the Create a Razor Web App section, there is no template in my install of VS2017.
I have both the .net core and asp.net and web dev workloads installed. Where have I gone wrong?
Open Visual Studio (assuming its 2017) and go to: Tools > Extensions and Updates
Click "ASP.Net and web development", then select the appropriate Individual Components in the right hand pane. You'll find components such as ".Net Core 2.0 Development tools" and ASP.Net web development tools"
Have you got the latest update for your Visual Studio installation?
Head to Add or Remove Programs
find Visual Studio
Click Modify
Allow the installer to update
Install any updates that are missing
On top of that, do you have the latest version of the .NET Core SDK?
It seems I had an OS issue that caused updates to fail. Have rebuilt the PC and all working as expected now. Very much a sledgehammer approach, but this was something fundamentally wrong with the installation.
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
has anyone else dealt with this? My ultimate goal is to create a new empty web api project. I've been following tutorials and I've encountered the following issue:
My issue is that when I try to create a ASP.NET Web Application project in Visual Studio Pro 2012 I do not see that template as an option. I go to Installed --> Templates --> Visual C# --> Web
All I see is ASP.NET Empty Web Application. So I selected that and then expected the ASP.Net project window to pop up so that I could select "Web Api". However, that dialog never opened.
Does anyone know how/where I can get the ASP.NET Web Application template?
I came across your question as I had the same problem. When I first installed Visual Studio I didn't tick the box to install the Web Components. Here is how I solved the issue:
Close all your instances of Visual Studio.
Run the Visual Studio Installer (I found mine in the Downloads folder still and was named "vs_professional.exe").
For VS 2013 a grey window appears similar to when first installing VS.
When prompted select "Modify" from the list of options.
Tick the list item which I think was named "Web Development" or something similar.
Click update.
Once the installer has finished running launch Visual Studio.
When selecting New Project in Visual Studio I can now see the required templates.
Try to select Framework 4.5.
The Framework 4.0 don't have :)

If you have ASP.NET MVC 4 Web Application as an option under Web when you select it as a new project the project window pops up and you will be able to select Web API.
kale909's solution worked for me. I just added pics here to make it more clear:
then here:
I am relatively new to Visual Studio and .NET and VB.NET. I recently installed the Amazon Web Services .NET SDK and I am trying to figure out how to get things running, specifically do I need to do anything to include the SDK in an existing project? I know there is some sample code, but its in C# and the project is already set up so I don't find it very helpful. Thank you.
I'm not a VB expert but you should be able to include the AWS dll to your existing project. That way you can use AWS API functions.
You can locate the dll using the sample project. (As I remember the name of the dll is AWS2SDK.dll or something like that..)
