I have a solution which contains 18 projects and targets framework 3.5. It also includes web installer project. When i am trying to upgrade the solution to framework 4.0, it gives me lots of errors and doesnt convert web projects and web installer projects.
Is there a way to convert projects manually rather than relying on visual studio wizard?
.wdproj files are not getting converted.
Error Log:
Project file opened successfully
No Conversion Required

ToolsVersion in String:

I understand that you want to change your framework for all the solutions from 3.5 t0 4.0
I think you can set that in visual studio 2010.
Open your entire solution in VS2010.
right click on the project (do this for all the projects you have)
then select properties.
Click on compile tab on the left side .
click on advanced compile options
change the target framework to 4.0
I'm not sure but I thought of sharing this idea.
Let me know if this works.
I always have kind of a hard time finding the setting in visual studio for changing the version of .NET. And even then sometimes it has been greyed out (unchangable) through VS GUI. The way I typically change .NET is by opening your .sln file in notepad. In a Visual Studio 2010 .sln file there should be a line in there something like:
TargetFrameworkMoniker = ".NETFramework,Version%3Dv3.5"
Just change it to:
TargetFrameworkMoniker = ".NETFramework,Version%3Dv4.0"
Save, and you should be good to go.
If you really want to change your framework through the GUI in Visual Studio 2010 for an asp.net project you can right click on your website (one tier under "Solution" in "Solution Explorer"). Select "Property Pages", then in the new window "Build" which has a field called "Target Framework" where you can change your .NET Framework.

I use Visual Studio 2019 (16.7.7). I created new ASP.NET Web Application (.NET Framework) with web forms. But in code behind “Find All References” doesn’t work for setter. And in .aspx-file I can’t “drill down” to user control definition. It seems like a plain text.
I can’t use a previous visual studio version. My current project contains a lot of web forms and also projects with PackageReference format
I had installed visual studio 2017 before. But I unistalled it according to https://learn.microsoft.com/en-us/visualstudio/install/uninstall-visual-studio?view=vs-2017 and https://learn.microsoft.com/en-us/visualstudio/install/remove-visual-studio?view=vs-2017 Also I several times have reinstalled visual studio 2019 but problem remains
Here are steps to reproduce:
Create ASP.NET WEB Application (.Net Framework) C#
Select Web Forms Template
At ViewSwitcher.aspx.cs file I have added public property
public string SomeProp { get; set; }
At Site.Mobile.Master file I have added value. Here intellisense works. It suggests property SomeProp.
<friendlyUrls:ViewSwitcher SomeProp="someValue" runat="server" />
Build.
Return to ViewSwitcher.aspx.cs. I do right mouse click on set of SomeProp and click "Find All References". But it doesn't show using from Site.Mobile.Master.
It is too difficult make any refactoring and rename without it
Maybe, visual studio have never had such feature. Previously I have used Resharper but now I can't use it.
The same true for visual studio 2017. windows 10
I suggest you could try the following suggestions:
1) disable any third party vs installed extensions under Extensions-->Manage Extensions-->Installed
2) clean nuget caches
3) run update-package -reinstall under Tools-->Nuget Package Manager-->Package Manager Console.
4) close VS, delete all the folders C:\Users\Administrator\AppData\Local\Microsoft\VisualStudio\16.0_xxxx to initialize your VS.
also, for your project, you should delete .vs hidden folder under the solution folder, bin and obj folder of your project.
Besides, if you still cannot get what you want, please click C:\Program Files (x86)\Microsoft Visual Studio\Installer\resources\app\layout\InstallCleanup.exe to clear all vs versions strongly, their registry information and data info.
Then, reinstall the VS again. If you have tried this step, then, you should try to turn off any antivirus software, other third party windows programs.
Update 1
Actually, it is quite strange. As to help you further, I have reported the issue on our DC Forum and you can vote it and add any comments if I did not describe the issue in detail so that it will get more Microsoft's attention. And I hope the Team will give you a satisfactory reply.
I just installed Visual Studio a few days ago and for some reason I can't create anything but a class.
When I go to create a new User Control the pop up window lets me do everything except for click the "Add" Button to close the window and create the control.
If I double-click the User Control selector to create automatically, it pops up an alert box that says I need to go to the installer to get the .NET Framework target libraries. But when I go to the project's properties I see that I am already targeting .NET Core 3.1 and the only other option I have to target is .NET Core 3.0.... I assume this is because I'm in a .NET Core WPF application but I have no idea why it won't let me create a new control. It won't let me create anything except for a new class.
What is going on here? How can I work around this bug?
I've faced your problem recently. most of the templates were not installed after installation.
something you have to do is Modify your installation.
open Visual Studio Installer and click on Modify then choose the features(.Net core,Asp.net, Desktop Application and etc) in order to re-install them.
keep it in mind that, if installer encounters any problem or missing dll. installation instantly will be completed that should not happen.
keep your eyes close to your installer process and make sure all packages are installed.
a successful installation MUST not have any warning otherwise there are packages not installed.
it's better to install packages one by one NOT totally. I mean if you want the Asp.Net Core feature then try to install it at first. then try to install another feature.
Actually, I was not able to install whole features in a single installation and I don't know why. in short, don't heavy your installation.
If the problem still exists then:
1. Close all open solutions
2. Run InstallCleanup.exe
C:\Program Files (x86)\Microsoft Visual Studio\Installer\resources\app\layout\InstallCleanup.exe
3. Remove all existing Visual Studio programs from Control Panel -> program features
4. Restart pc and re-install Visual Studio
5. Make sure you have connected to the network
6. Choose only one feature(Don't select all) to install + Visual Studio Editor
vs bug
Extensions don't work properly in VS 2019 and make it hang. it's may happen because the Extensions have to be updated to be compatible with vs 2019 or it's vs bug.
I am following this setup tutorial
https://docs.asp.net/en/latest/tutorials/your-first-aspnet-application.html#create-a-new-asp-net-5-project
And have come across a problem. In the tutorial the instructions are as follows:
Start Visual Studio 2015. From the File menu, select New > Project.
Select the ASP.NET Web Application project template. It appears under
Installed > Templates > Visual C# > Web. Name the project ContosoBooks
and click OK.
This is fine, but in the next step :
In the New ASP.NET Project dialog, select Web Application under
ASP.NET 5 Preview Templates. Also, make sure the Host in the cloud
checkbox is not selected and click OK.
I am seeing no ASP.NET 5 Preview templates!
The only thing I am noticing is that my Authentication states No Authentication but I am signed in so I am not sure what this means or whether or not this is a factor.
The version I have installed of Visual Studio is "Community 2015".
I have already gone through the perquisites as outlined in This Article.
I am hoping that someone with a more thorough knowledge on the topic can help me out as I have not been able to find any threads etc. of the same issue or what could be causing the Templates to be missing.
Asp.net 5 templates no longer exist - they are renamed to Asp.net Core: ASP.NET 5 is dead - Introducing ASP.NET Core 1.0 and .NET Core 1.0
So, when creating your project, instead of picking "ASP.NET Web Application" as it is in the video - you would select "ASP.NET Core Web Application" and then on the next page those 3 templates (Empty, Web API, Web Application) are the same as the video's asp.net 5 preview templates
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.
I have concluded, by following another stackoverflow question on How to check the ASP.NET version loaded on a system as I noticed that the templates were categorized in the ASP.NET versions (4.6.1 & 5) in the tutorials but mine were not.
So I then checked and my files in C:\Windows\Microsoft.NET\Framework are as follows
Revealing no v5.0 directory. I rectified this and now all of the templates are available
AMENDMENT:
To fix it:
I went to http://www.asp.net/downloads and downloaded ASP.NET MVC 5
I ensured I had Developer Tools checked in the download process.
This issue was now resolved - As I then had the MVC 5 template files. Because I downloaded them, so I had them... and no longer didn't have them.
ALTERNATE FIX:
Furthermore From my research, some people had not included Developer Tools. To resolve: go to old mate 'Add or remove programs' and find your Microsoft Visual Studio 20xx install, 'change' and install Microsoft Web Developer Tools
I have had the same problem but it is actually even better because "The new dialog enables you to change the default authentication options for many of the templates. For example, when you create an ASP.NET Web Forms project you can select any of the following options:
No Authentication
Individual User Accounts (ASP.NET membership or social provider log in)
Organizational Accounts (Active Directory in an internet application)"
check out this >> http://www.asp.net/mvc/mvc5
I recently had this problem and finally fixed it by uninstalling (control panel -> uninstall a program) Microsoft.NET Core and Microsoft Visual C++ redistrutable 2015 (x64 & x86) and then re-installing the asp.net core rc2 (https://www.microsoft.com/net/core#windows or possibly check Tools->Extensions and Updates->Updates inside of Visual Studio).
I uninstalled the Visual C++ redistrutables because I kept getting an error when trying to re-install asp.net core rc2. It kept telling me that it already existed even after I had just uninstalled it and the update was showing in the "Extensions and Updates" section of Visual Studio after trying (but failing) to install the asp.net core rc2 update.
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:
