I am receiving error while launching my application on windows. I have installed the updated version of visual studio and both window and visual studio are compatible with each other with SDK(10.0.19). Here is the picture showing error.

I tried to open basic c# console application project and whenever I click the project in visual studio 2019 I receive the message like this.

I've tried removing and reinstalling in visual studio installer app. But I couldn't figure it out.
Recently started using Visual Studio 2012, converting SSIS packages from 2008, and seem to be unable to set breakpoints in Script Tasks. The error we're receiving says
Cannot start debugging. Pre-debugging negotiations with Host failed.
Cannot seem to find any information about this error, or what's causing it. There is also a brief flash of a dialog box that says
Visual Studio has encountered an unexpected error
but that disappears quickly.
This issue has been resolved. The input parameters were set incorrect and hence was failing. It has been fixed now
I think you install new version of Visual Studio you just have to uninstall the Visual Studio tools for Application for the new version then repair the Visual Studio tool for Application 2012 and every thinks will be good
Debugger error “Unable to attach. The System cannot find the file specified” from the Ripple and Android emulator
I've just installed the Multi-device Hybrid Apps preview for Visual Studio 2013, and I'm getting an error when attempting to debug against Ripple or other emulators
The build process is always completed successfully, but while start debugging the VS show up this error message:
“Unable to attach. The System cannot find the file specified”
There is no useful output provided by Visual Studio 2013, rather the debugger just doesn't attach to the browser Ripple emulator after showing the exception.
The exception happens immediately and the debugger never attaches.
I've had this error occur since installation, so it shouldn't have anything to do with the project itself.
I checked my paths and they appear to be correct as in #Freddy's answer, because the build is always successful.
This may happen when Visual Studio is installed on a non-system drive. If that's the case, you can work around it by copying the assembly typescriptSourceMapReader.dll from
<SystemDrive>\Program Files(x86)\Microsoft Visual Studio 12.0\Common7\IDE\PrivateAssemblies
to the same location on the drive where Visual Studio is installed.
Relaunching VS after doing this should fix the issue.
I have re-installed windows today Windows 8 Professional.
Have installed Visual Studio 2012 without any errors or problems.
Enabled Hyper V.
But i cant see designer it shows only blank white page:
And when i Launch any Windows Store project on Local Machine it shows Splash screen and the blue screen:
And when i try running it on simulator i see this:
What is the problem? and how to fix it?
P.S. Before all worked fine
Visual Studio updating, repairing and reinstalling didn't help
I don't know how, but updating to Windows 8.1 solved the problem
Visual Studio 2013 Professional crashes when I try to open the Debug tab in the properties panel of a Windows Phone 8 project. No error given only "Microsoft Visual Studio 2013 has stopped working". Attached Visual Studio as a debugger and got the following error:
An unhandled exception of type 'System.NullReferenceException' occurred in Microsoft.VisualStudio.SmartDevice.ProjectSystem.Base.dll
I'm running Visual Studio as an Administrator
I have the same problem with a very weird behavior. The first time I create a WP8 project in VS2013 I have all the options for emulators, the designer, the devices and even the debug tab of the project working fine. All the markup of the mainpage.xaml is ok. If I close and reopen a new instance of the project in visual studio 2013, everything start having problems: I can not open the debug tab, the emulators optios are gone, the device windows appear in read only mode, The markup of the xaml says an "Invalid Markup" and got errors like:
The name "PhoneApplicationPage" does not exist in the namespace "clr-namespace:Microsoft.Phone.Controls;assembly=Microsoft.Phone".
BUT: It compiles and run in the emulator.
I also DO have all the Xamarin tools installed. It seems I am not getting this errors in Visual Studio 2012.
SOLUTION: From Xamarin Studio check for update and install the android SDK 4.10.2 and GTK# (2.12.0.0). At the time of this writing you have to subscribe to the BETA Channel to get this update. After installation you DONT have to delete de .suo file of the project and everything looks fine again in Visual Studio 2013
