  • It would be very unusual for differences between two minor subversions of a .NET Framework caused programs targeting that major version (4.6 in your case) to stop working.

    I suspect that your problem is with framework corruption, not a subversion difference.

    You said: "All EXE programs in managed code don´t run . (console, WinForm, WPF, no program run)".

    Do you see any error message(s)? If so, please quote them.

    Can you upload on of the failing .exe files to your OneDrive and post the link here so we can see what is going on?

  • Thanks for try help me,

    In all cases inside Visual Studio 2013 and 2015 in realise mode all programs runs correct. In debug mode i can make pauses and make breakpoints etc.

    After compile in realise mode i try run EXE file outside of visual studio and don't run.

    (I compile in framework 4.0, 4.0 Client, 4.5 and 4.5.1)

    No message are sent. Explore windows stay with "wait cursor" for long time and some times block the explorer window. 

    In Win7, task manager show all program that i try executed and i can't kill them.

    In Win10, Task Manager don't show programs but i now they are started because i can't recompile again (the file is in use)

    i will be going crazy?!?!?!?

    I work with Visual Studio .Net since first realise and i never have any problems 

    Help me resolve or understand


    Note; i make a copy of EXE program that no runs to my Job and there run withou problems!!! (WIN7 ultimate x86 with visual studio 2012)

  • hello,

    I'm very angry, a month later I discovered the problem !!!! It is the anti-virus "avast"  that blocking all executable .NET :(
    for other reasons i stopped "avast" an hour and in this time i run one my utility .net ........and Run ok (HUMM?!?!?!?)

    Then i tested in all my machines and i confirm, it is the avast.
    Are unbelievable the symptoms with avast connected:
     1 - the .NET executable does not run (and blocks the explorer)
     2 - i cannot not delete the executable (meaning that is running in background)
     3 - in Task Manager appears 3 executables (instances)
     4 - o cannot kill any instance.
