Trying to run an old project in Visual Studio 2015. It was created in 2012 or 2013, I cannot remember which. I have uninstalled both programs as I was running out of space, and i think that is what caused this. I get the following options:
And I do not want to change the target, so clicking on the second option brings me to https://www.microsoft.com/net/targeting which I can't seem to find anything there that remedies the situation. Is there a way around this without reinstalling the old version of Visual Studio again? Will that even fix my problem? Thank you.
Just Reinstall Visual Studio. When you uninstalled previous version it caused this problem.
You could try doing a repair reinstall of Visual Studio 2015.
Another point to consider is that Windows 7 (the oldest version of Windows still supported by Microsoft) includes a Windows Update for the .NET Framework v4.6.1 categorized as an "Important" update. I have not confirmed with Windows 8, but I suspect it, too, includes a similar update. Windows 10 comes with .NET 4.6 to start with. That means that any up-to-date supported machine today will be able to run apps targeting any .NET version up to and including 4.6. I recognize that there may be other reasons to continue targeting an older .NET version, but I bring this up just in case the concern is support on client workstations.
I have a windows 8 pc, I recently installed windows phone 7.1 sdk but it continously gave me the error that it couldn't install XNA 4.0 Refresh and MS VS 2010 Extensions for XNA. When I make a project of windows phone and run it it gives me this error:
Error 1 The target "GetCopyToOutputDirectoryContentProjectItems" does not exist in the project. PhoneApp2
Any suggestions/solutions would be greatly appreciated!
Thanks :)
If you are running visual studio 2010 on Windows 8, then following the steps here should work:
http://www.demonixis.net/blog/installer-xna-4-0-sous-windows-8/
If possible you might want to uninstall what you have for xna and the windows phone sdk so far. (I'm not sure if it would work properly without doing so.)
Basically, it has three steps:
1)Go to xbox.com/en-US/LIVE/PC/DownloadClient
Start by pressing the download button on this page. I am not sure what the significance of downloading that client is, however, it did the trick when I installed it.
2)Then reinstalling xna on this page:
microsoft.com/en-us/download/details.aspx?id=23714
3)And this last step is to download Windows SDK 7.1 here:
microsoft.com/en-us/download/details.aspx?id=27570
I have a C# console app in Visual Studio 2010 that I can run just fine. When I attempt to run the process in debug mode, I am presented with the following error:
I have tried searching for any information, but I haven't been able to find anything. Can anyone provide clues as to why I can't run this with the debugger?
EDIT: I should clarify that I have been able to successfully debug a console app previously, this is a new situation.
From what I can tell when I'm able to reproduce this error, it is caused by being in the middle of installing Windows updates. So, running updates, then postponing a reboot, then attempting to debug code is what was putting me in this broken state.
I had this issue once and it was caused by an pending Windows Update on the Server where the process was running, which I wanted to attach.
I encountered the same issue. It happened to me when I attempted to attach to a process for debugging purposes. At the time I had postponed a pending windows update.
Everything started working fine after I restarted my computer and allowed the update to take place.
Additional notes: I had recently updated to Visual Studio 2010 Ultimate and installed its Service Pack 1.
I had this when I installed .NET 4.6 for Visual Studio 2013.
In this particular case, restarting Visual Studio 2013 solved the problem.
I have finally solved this!
It seemed to have happened after I updated my Windows 7. One of my files must have been out of date.
The fix: Install VS 2010 Service Pack 1
Worked correctly right after I installed. Hitting breakpoints and everything!
Hope this works for you too!
I also updated to Service Pack 1, and made sure Windows updates were up to date, but I was still having the same issue:
"The Version of CLR.dll in the target does not match the one mscordacwks.dll was built for."
Microsoft closed this issue on connect.microsoft.com as not reproducible... Unforgivable, irresponsible support system!!
But on social.msdn.com I was directed to upgrade through this link, and this has resolved the problem in my machine ( Win7,VS2010,target 4.0)
Hope it helps.
Simply. Restarting Visual Studio solved the problem in my case.
I had VS 2010 SP1 for ages and had rebooted many times. There wasn't any windows update in progress either. I closed all my VS 2010 IDEs and then opened them, and the problem was gone.
This happens, when you do a WINDOWS UPDATE and haven't rebooted your system and the update isn't compatible with VISUAL STUDIO. So in order to solve this, just do an update on VISUAL STUDIO to latest. That should FIX it
I had this weird issue after installing .net framework 4.5, when using .net 4 for my project.
updating VS 2010 service pack didn't solve this, only removal of .net 4.5 and 4, and then reinstalling .net 4 only.
I have VS2013 on Win7 and restarting VS worked for me. Seems it is a VS/CLR bug.
I tried installing MVC 3 from the download in http://www.asp.net/mvc/mvc3 - both with and without the Web Platform Installer. As soon as the download is finished, the installer says installation is finished, yet I get no observable effect - I can't create MVC projects and it doesn't appear in Uninstall Programs.
Any idea how I can get MVC 3 to install?
Edit: Forgot to mention, I have the just-released SP1 installed.
Look in the eventlog to see if there any errors related to Windows Installer.
We had a similar issue, because we had the SP1 beta installed. Uninstalling the beta, and then running the installer worked for us.
When I try to install the new phone tool application, it requires me to remove the previous beta version in order starting with phone developer tools beta. so go to control panel uninstalll I click on tit it gives me an error. "a problem has been encountered while loading the set up components. canceling set up" Anyone help please. thank
This happened with my VS 2010 Beta. I used Revo Uninstaller and removed all file/registry entries and then installed the latest version of VS 2010.
Sometimes things get a bit messed up when installing and uninstalling lots of ctps. Try this uninstall/reinstall sequence for anything that might be getting in the way.
