I am using the PopupWindowAction from assembly 'Microsoft.Practices.Prism.Interactivity'
When I build my application the build succeeds and the application runs and works correctly however I loose designer support for my view due to the following error:
The type 'PopupWindowAction' from assembly 'Microsoft.Practices.Prism.Interactivity' is built with an older version of the Blend SDK, and is not supported in a Windows Presentation Framework 4 project
This issue did not occur in visual studio 2013. Can anyone suggest how I resolve the issue?
I had the exact same problem, and I finally resolved this by reinstalling Visual Studio 2015. I did this after realizing that my colleagues did not experience the same behavior.

Getting Error like this when opening a C# script from unity-3D on Visual Studio 2019.
Required v4.7.1 which is already installed. I even tried changing it to 4.0, 4.5 and 4.8 but its still not working.
Solved. I tried installing 2020.1.5f1 Unity3d without visual studio setup at first which led on missing few component on visual studio required to run the c# project.
I tried installing again without missing any component and it worked fine.
I am currently using Visual studio community 2019 version 16.1.3 I created a new web application - Blazor. I have made no changes to this new application.
Everything blazor related is showing up with the red line and
Error CS0103 The name 'currentCount' does not exist in the current context
The application does run though. Am i missing something to be able to use the intellisense with blazor?
The problem is that at the time of this question Blazor is still not released. I had installed Visual studio 2019 which did have blazor support but unfortunately the in intellisense only worked in Visual studio 2019 preview.
This is the anwser that was given in one of the comments above.
Updating to the latest preview version is what fixed it for me.
Yes, i've tried devenv/install, with no help.
So, I don't have the Console C# Project option when creating the project,
as shown here
Currently i have installed windows basic pack - there's my 'about' screen.
I have just reinstalled Windows because i was getting the same exact problem on old system, and because VS2015 had interface bugs and crashed consequently, but it didn`t help(as well as reinstalling both VS 2015 and 2017 numerous times)
Hope that you can guess whats wrong with my PC.
Visual Studio 2017 setup allows you to very fine-grainedly install various "components" separately, or groups of components delivered as "workloads".
You're missing the workload named ".NET desktop development", which contains among others these project templates. So re-run setup and install that workload.
You have a link, Open Visual Studio Installer in a New Project window that will allow you modify your installed components
I'm encountering a strange bug in visual studio that seems to be caused by a specific Nuget package named Ragnar. The package is, by its own description
"a C++/CLI wrapper for Rasterbar's libtorrent. It aims to provide a (mostly) complete interface to the underlying C++ library."
I've reproduced the bug across multiple machines. So far I've tested Visual Studio 2013 on Windows 7 Ultimate and Windows 7 Professional.
Steps to reproduce:
Create a new WPF project
PM> install-package ragnar
Save all and restart Visual Studio 2013
Reopen the project from the Visual Studio 2013 start page.
Errors:
System.Runtime.Remoting.RemotingException
[5448] Designer process terminated unexpectedly!
The exception unknown software exception (0xe0434352) occurred in the application at location 0x74efc42d
There is not enough virtual memory available. Please save your work and restart (0).
The instruction at 0x7740e823 referenced memory at 0x00000024. The memory could not be read.
At this point Visual Studio 2013 becomes unresponsive and needs to be killed via the task manager. Removing the reference created by Nuget stops the issue, so I've confirmed it's Ragnar.dll that's causing the issue.
Any ideas what could be causing this? Is this a Visual Studio bug or just weird behavior caused by a buggy class library?
If this is a bug in the package itself, please contact the owner of this package and ask them to update the package. https://www.nuget.org/packages/Ragnar/0.1.0
Today I have installed Roslyn September 2012 CTP. I began with a sample console project. After the IDE finished creating the project code, I pressed F5. I ended up with a dozen compilation errors saying none of the Roslyn namespaces found. However the intellesence options are working fine for those references.
I tried with restarting the Visual Studio and even the my PC as per suggestions I found elsewhere. But none could resolve this. Is there anything that I am missing?
Rep whoring :)
As posted in the comments, this generally happens when there is a .NET Framework target mismatch. Your Visual Studio will be targeting a different version of .NET than what the project or a project reference was developed in.
