When I am trying to run an ASP.Net Core project in Visual Studio 2015, a Microsoft Visual Studio dialog appears "The project doesn't know how to run the profile IIS Express".
Does anyone know anything about this message, or how to fix it? I've searched Google and the MSDN. There's nothing in the build logs, or the Windows event log.
This dialog showed up for me when I had migrated a project from dotnet RC1 to RC2.
Before the fix I could still run it using dotnet run and from Visual Studio choosing the profile other than "IIS Express".
I had misread this guide and forgot the .Web
\DNX\Microsoft.DNX.targets –> \DotNet.Web\Microsoft.DotNet.Web.targets
After fixing this and restarting Visual Studio(not sure if needed) I could run the project using the IIS Express profile.
Should also be noted that as per the comments, adding .Web in the top level node is required in the xproj. <Project Sdk="Microsoft.NET.Sdk"> should be <Project Sdk="Microsoft.NET.Sdk.Web">.
In my case the issue was solved after added the ASP.NET and web development tool extension to my VS instalation.
To clarify the answer from hultqvist, it is a problem with the xproj. To fix it, edit the xproj directly and change this
<Import Project="$(VSToolsPath)\DotNet\Microsoft.DotNet.targets"
Condition="'$(VSToolsPath)' != ''" />
to this
<Import Project="$(VSToolsPath)\DotNet.Web\Microsoft.DotNet.Web.targets"
Condition="'$(VSToolsPath)' != ''" />
That is, insert Web twice.
There is an associated issue in the aspnet tooling repo.
I had the same issue and found a very simple solution for Visual Studio 2017. In Visual Studio 2017 go to Solution Explorer then right click on your project file. In the menu you will see "Set as StartUp Project". If you can select it then select it. Now run your project again.
I had a similar issue but with "MyProjectName" instead of IIS Express.
In my case, I was trying to start as a standalone application, so I cleaned the launchSettings.json
I inadvertently changed the "commandName" parameter from "Project" to "MyProjectName" and that caused the popup to show up.
Resetting it back to "Project" solved my issue, silly me 😁
I had a similar issue, In my case ASP.NET and web development is enabled but Development time IIS support is not checked in the optional sections.
Once I enable the Development time IIS support solved my issue.
You can get this error with RTM if <BaseIntermediateOutputPath gets corrupted or is incorrect in your .xproj file.
I had this same issue and after digging around for a while I discovered that I had dotnet preview v1.0.0-preview2 installed under Programs Files (x86) and a non-preview version in x64. I think VS is launching the x86 (preview) version but expecting to see the full version. To fix this, I did the following.
from programs and feature uninstall every visible dotnet core. (note: this did not remove the x86 preview)
go to https://www.microsoft.com/net/download/core#/sdk and install BOTH x86 and x64 SDK packages
open command line and from the root directory check run: dotnet --version (at the time of writting it was 1.0.4
fire up .net core project in VS 2017 and run.
When I did all of the above, I was able to start up the site in IIS Express from VS.
This happened to me after a failed update of visual studio 2017 15.9.4
Setup completed with warnings and when I checked the problems saw that .NET core SDK 2.1 installation is failed.
I will try to install it manually.
Otherwise currently the only solution I found is to uninstall visual studio and re-install it.
In visual Studio 2017, i fixed this error by doing the following two steps.
I went to add or remove a program in windows, and deleted everything ending with ".net". I then reinstalled them in the visual studio installer. Then loading the project again produced a new error, which condiosluzverde provided the solution to here:
How Can I Fix the Microsoft Visual Studio Error: "Package Did Not Load Correctly"?
Same thing happened to me, my project was working fine. I didn't do any RC1 to RC2 update & this popup appeared from nowhere.
I fixed the problem by updating visual studio. You can also consider repairing VS.

This has been the case unfortunatly for the past couple of months. I can't install new or update packages from Tools ==> Extensions and Updates I tried everything, yet I am unable to find the reason.
I've tried :
Access NuGet and download packages from "Package Manager Console" Install-Package = SUCCESS
Access repositories using Web browsers, Visual studion internal browser = SUCCESS
Same window in Visual Studio 2010 = SUCCESS
Visual Studio 2012 - Doesn't work
Visual Studio 2010 - Works!
As it turns out for some reason -possibly due to an RC-, My registry settings were pointing to a different url that was getting redirected.
HKEY_CURRENT_USER\Software\Microsoft\VisualStudio\11.0_Config\ExtensionManager\Repositories
AND I changed
HKEY_CURRENT_USER\Software\Microsoft\VisualStudio\11.0_Config\ExtensionManager\Repositories{0f45e408-7995-4375-9485-86b8db553dc9}(Default)
to
http://visualstudiogallery.msdn.microsoft.com/Services/v2011/Extension.svc
instead of
http://go.microsoft.com/fwlink/?LinkID=251029
I changed
HKEY_CURRENT_USER\Software\Microsoft\VisualStudio\11.0_Config\ExtensionManager\Repositories{aeb9cb40-d8e6-4615-b52c-27e307f8506c}(Default)
to
http://code.msdn.microsoft.com/Services/v2011/sample.svc
instead of

Remove the local cache of extensions and download them all again.
The easiest thing to do is to rename
%LocalAppData%\Microsoft\VisualStudio\Visual Studio version\Extensions\
to
%LocalAppData%\Microsoft\VisualStudio\Visual Studio version\Extensions.old\
and run visual studio, it will update recreate the folder.
WeSam Abdallah's hint worked perfectly for me! Just try to open the link provided in HKEY_CURRENT_USER\Software\Microsoft\VisualStudio\12.0_Config\ExtensionManager\Repositories{0f45e408-7995-4375-9485-86b8db553dc9}(Default) in your browser and see what it is changed to automatically. For Visual Studio 2013 I had to change the URL from https://go.microsoft.com/fwlink/?LinkID=309922 to https://visualstudiogallery.msdn.microsoft.com/services/dev12/extension.svc
This answer is an update for Visual Studio 2015.
I tried the registry hack as well as renaming the Extensions folder, and neither solution worked.
However, in my case, the issue seems to have been because I'm behind a proxy at work. This worked for me:

I have visual studio express 2012
and it was working fine earlier I had run my solution once. But now when I do it, there appears a dialog box with the message!
the Microsoft.VisualStudio.Web.PasteJson.JsonPackage, Microsoft.VisualStudio.Web.PasteJson package did not load correctly.
the problem may have been caused by a configuration changhe or by installation of another extension. You can get more information by exmamining the file
C:\Users\AppData\Roaming\Microsoft\VWDExpress\11.0\Log.xml
continue to show this error message?
How do I get rid of this error?
I started to see this on the fresh windows & VS 2013 Ultimate with Update 2 installation.
To resolve the problem, close all Visual Studio instances head over to
C:\Users\<your users name>\AppData\Local\Microsoft\VisualStudio\12.0\ComponentModelCache
and delete all the files in the folder.
It worked fine for me. Thanks to this article.
Not relevant to VS 2012 express, but I experienced this problem with VS 2013 Premium. I had recently added the productivity power tools extension. To get back up and running, I loaded Visual Studio in safe mode:
C:\Program Files (x86)\Microsoft Visual Studio 12.0\Common7\IDE>devenv /safemode
And un-installed the productivity tools. The errors went away.
You need to clear the ComponentModelCache folder or rename it. For Visual Studio 2013, it’s located in the %LOCALAPPDATA%\Microsoft\VisualStudio\12.0 folder.

I had Visual Studio 2013 Professional and I got the same error. I couldn't remove it until I repaired VS installation. It took a while but now it works fine.
I had this problem as I had an older version of VS2012 Express (release on Web Platform installer dated 15/08/2012).
Try installing 'Visual Studio 2012 Express for Web (Latest)' with release date 22/10/2012 from the Microsoft Web Platform Installer.
That is all I did and I no longer get those messages.
I am using Visual Studio 2012 and Xamarin.Android Beta release to develop an Android application. When I try to deploy the android application for debugging purposes onto an Android device, it deploys the previously built application on the device and not the recent changes I made and deployed (i.e No refresh of build). However, if I use Xamarin Studio to do the same, it deploys the correct build everytime (i.e refreshes the build with new code changes).
Any idea why this is happening?
Thanks in advance!
I had a similar issue: With Visual Studio 2019 the debug version of my driver was deployed while building the release version.
The cause of my problem was, that in the Properties -> Driver Install -> Package Files I had an absolute path pointing to the debug version of my driver in the column File. This setting is valid for all configurations (not separated for debug/release), and when entering macros, they are immediately expanded to absolute paths.
I fixed this by editing the .vcxproj file with my favourite editor and changed the path back to $(TargetPath).
I had the same problem. My solution was to add "deploy" to the build configuration:
BUILD => Configuration Manager... => (select "Debug" from left-hand combo-box) => (tick "Deploy" in grid)
Courtesy of this xamarin forum post.
I have no idea why it does this, I had this issue before. I also noticed that the device log was somewhat behind (ie, at 3.30pm, the last record on the device log was 11.00am).
Uninstalling the app from the device and re-deploying it seems to correct it.
Note: I had this issue in VS, didn't check with XS.
I would look at the difference in your deployment settings in VS and XS (I think it may have something to do with the Fast Deployment option).
Similar question (though for iOS Simulator) here.
I had a similar problem (though on an Android emulator).
What didn't work for me:
restarting the computer
restarting Visual Studio
deleting bin / obj folders
going into Configuration Manager (Debug / Release / Configuration Manager) and ticking everything there - everything was ticked
changing the version of the app in the manifest
What worked for me?
Uninstalling the app from the emulator and then running Debug again.
It was an Android emulator, so I uninstalled by clicking on the app icon and holidng for long, and then dragging it to "Uninstall App". On an iOS simulator it should be similar.
I am getting an Exception when I am trying debug my application on Emulator (Web Role).
you can see exception by clicking following link
Configuration which I am using Windows 7 pro, VS 2012 Pro, Azure SDK 1.8
Hope it might help others.
I Also had the similar problem and I restarted PC and **Run Visual Studio as Administrator**.
And let Visual Studio start the emulator with same privilege resolved the issue.
I was using Visual 2013 and Web API application under IIS Express.
Do you have IIS added? Most likely it's already installed but you've to enable it via Add Windows Compoenents on Control Panel...
I had this same issue all of a sudden, luckly I remember changing the ServiceDefinition.csdef file. I rolled this back to an earlier version and the debugger ran again correctly. The only thing I changed in the 'broken' version was instance size from small to medium.
Go to visual studio installer(search it from window's start)
and update the visual studio.
After updating, hit modify
button, after that on right side you will find a box named
debug (or something like that), select that box
Then hit install.
Restart your visual studio and debugger will start working.
In my case it worked perfectly.
In the Visual Studio 2012 RC, I can't install Web Developer Tools properly. None of my ASP .NET MVC project will load in VS2012, and I can't create new ones. The option for ASP .NET MVC projects is simply not there, as shown below.
Furthermore, I can't pick any other framework than the .NET Framework 4 and earlier. I can't seem to pick .NET 4.5, but that may be because it's just an addition to .NET 4.0. That I don't know.
I'm running Windows 8 Release Preview, which should have .NET 4.5 RC installed already, so that shouldn't be the problem. Furthermore, if I click "I want to download more .NET redistributables", I'm taken to a site which says that Visual Studio 2012 RC has that included already.
I can't seem to download MVC 4.5 and install it separately. This is because they claim that it's included already in VS2012 as well.
When I try to click "Modify installation" in my Visual Studio 2012 RC installer, I see the following.
What's interesting here is that "Web developer tools" is never checked. If I check it and click "Update" and reboot, it's unchecked again, and it seems as if this whole feature is missing. I suppose that's really the cause of the problem.
I tried reinstalling Visual Studio 2012 RC entirely by first removing it, then rebooting, and then re-installing it. Running a setup repair doesn't work either.
I have managed to find no other examples of such a problem so far anywhere.
Can you help me?
Edit 1
I just found another weird symptom. Whenever I want to make a "Windows Metro Style" application, it doesn't work either, coming up with this message.
Like I said before, this may indeed be because it's not detecting that I have .NET 4.5 installed already, but I'm not sure. All I know is that I can't pick .NET 4.5 from the frameworks list at all.
On the ISO, I extracted the packages/WPT folder. Inside are all of the installers for the Web tooling components. I uninstalled and then reinstalled everything that had vs11 in the name and it worked!
