Pictures on Multiple Forms crash VB 2019 projects - vb.net

Using Visual Studio 2019, VB Windows Forms App(.Net Framework) template, my students are building projects using multiple forms, pictures (as background images and in picture boxes) and timers. When they have two or more pictures, the programs crash irretrievably.
The error message is:
Error while trying run project: (path to project location) Access is
denied.
Even if they remove the pictures, the error remains and the program no longer works. I never experienced this problem when we were using VB2015.
My student assistant tried to replicate the problem on (Vis Studio 2019) his home computer and couldn't.

If you're using an antivirus you may add an Exception to the project path.
You may also try to run VB2019 as Administrator to see if that was the problem, click on the VS2019 icon using the right button of the mouse and then click on Execute as Administrator.

Can't run UWP release executable outside of Visual Studio 2017

I am using Visual Studio 2017 on Windows 10 with the official UWP sample code.
There is a UWP sample called basicinput that runs as a release build within the Visual Studio IDE without a problem.
My problem is:
when I attempt to run the release basicinput.exe executable by a mouse click (outside of the Visual Studio environment) I get an error saying that some DLLs names of the form vs*.dll can't be found.
I did a search for those .dlls and tried moving them to same folder as basicinput.exe, but then the application just hung.
What don't I understand?
What am I doing wrong?
As #Chuck-walbourn says, your application will appear in the Start Menu. If you want to deploy it to another computer (that doesn't have VS installed) you will need to create AppX packages using the menu item Project -> Store -> Create App Packages.... If you need more help with that. see the MSDN docs.
If you want to run your app from the command-line or from the Win+R dialog (with a simple name like foo.exe) you can create an appExecutionAlias for your application.

XAML Designer System.Runtime.Remoting.RemotingException

I'm encountering the following
System.Runtime.Remoting.RemotingException error when I create a blank
Windows 10 Universal Application...
Following are event viewer screens...
I have checked online for other solutions and have already done the
following...
Uninstall/Repair Visual Studio 2015 Update 1
Reset my Windows 10 PC 1511 update
Cleared the Designer/ShadowCache folder
Target environment has been set to x86/x64
Target framework set to 10240
Developer mode enabled
Updated graphic drivers
Have cleaned and rebuilt solution
Updated to VS15 Update 2
Please let me know if you have been able to find a solution to the above
UWP applications fail to launch from Visual Studio if project location and Windows Store apps installation path are on a non-default drive. Also, the XAML Designer will crash if you install Visual Studio and Windows Store apps to a non-default drive
Windows 10 allows users to change the default storage location of Windows Store applications. If you select a non-default drive for your apps, and if you install Visual Studio 2015 onto this drive, the XAML designer will not start and Windows Store app projects built on this drive cannot be run from Visual Studio.
Note: the workaround below will make any Store apps installed to the secondary drive inaccessible until next restart.
The file system driver can be temporarily disabled by running the following command from an admin command prompt:
fltmc detach filecrypt :
This will enable both running apps from this drive as well as usage of the XAML designer until the machine is restarted.
For a longer term fix, move your app or Visual Studio install to your system drive, or a secondary drive that has never been the storage location for Windows Store apps.
I had the same problem. I started visual studio as an administrator and the designer came back.
You might want to try to clear the XAML Designer Shadow Cache. I've fixed al sorts of ailments with this process.
Its been a few months but I have finally been able to get the XAML Designer to work.
As #peterfaraday mentioned, the XAML Designer only works if you install Visual Studio on the System Drive (C: in my case) instead of using any other drive.
After uninstalling Visual Studio keep the following things in mind...
If your system partition is small, look to increase the space as the installation can take a lot of space based on the components selected.
If you had already installed VS on any other drive, while reinstalling you will not be able to change the default installation directory.
This is because your initial path of installation was saved as in the registry. I tried solving this issue by following these steps. In my case I had found multiple keys in the registry and hence "Reset this PC" (Windows 10) by allowing only for my personal files to remain. This cleared out all the registry keys and I was able to install VS back on the C: drive, resulting in the XAML Designer finally working (Please note that resetting your pc will remove any applications installed on your machine)
I got the same problem months ago. I Cleared the cache and Rebuild the solution. I got success.

Visual Studio Tools for Office VSTO "customization assembly could not be found or could not be loaded"

I just installed Visual Studio 2012 Ultimate and I am trying to create a managed code extension project for Excel 2010 (32 bit Office Professional Plus). I have tried using the .NET 4.0 template contained in VS Ultimate for an Excel 2010 workbook. When I create the project everything looks fine until I run it.
Excel opens and I get the error message "The customization assembly could not be found or could not be loaded. You can still edit and save the document. Contact your administrator or the author of this document for further assistance." The details section is blank.
I have tried everything I could think of to figure this out and I have run out of ideas. I removed all addins from Excel except for the VSTO Design-Time Adaptor for Excel. I removed all personal macros. I set every directory I could think of to "trusted" in Excel and lowered the security settings for all options to "enabled (not recommended)". I completely uninstalled Visual Studio and re-installed. There are no errors or warnings showing up in Visual Studio. I also checked to make sure ".NET Programmability Support" was installed for my copy of Microsoft Excel.
I would link my code but I haven't written anything. I can't even get the default template to load when I run the project. A few others at work have the same setup as me and VSTO runs fine for them using the same steps. I even had someone send me a working project but it gives me the same message when I try to run it.
Is there anything else I can check to see where the problem is occurring? I tried setting break points in the project but it is failing before it gets to any of them.
Thanks so much for your help.
I've run into the same problem with Visual Studio 2010.
I isolated the problem to an SSRS reporting link we were trying to run from the add-in. I removed all the reporting stuff (service reference, sub-dirs, etc.) - the add-in runs fine.
We just ran into this and discovered that a method had a system exception that was not handled. It was hard to track down but once the culprit method had an exception handler the customization finished loading properly.

Class running when I open VS 2012

I'm working on Visual Studio 2012, on a .NET project.
I have a class that pops up a window asking the user for input. The window isn't set to show up at start-up.
Whenever I load my project, before I even build it, that class starts shows up.
When I run my program using the exe file, I don't have the same problem.
Does anybody know how I can prevent it from happening?
Thanks

Unable to start debugging - Visual Studio 2012

"Unable to start debugging 'C:\Windows\System32\WWAHost.exe'. The Microsoft Visual Studio Remote Debugging Monitor (MSVSMON.EXE) does not appear to be running on the remote computer. This may be because a firewall is preventing communication to the remote computer. Please see Help for assistance on configuring remote debugging."
Searched for similar posts, but didn't found one. If duplicate just inform.
I am not trying to connect to any remote machine. Just testing on my local machine.
Is there any way to solve this issue. (I'm using Windows 8 Enterprise 64-bit, just a javascript project)
Problem solved. Installed Remote tools update from here and working fine. Thanks for responding. Closing the topic.
I had the same problem. I fixed it by changing properties/compile/target platform to x86 instead of Any CPU. It solved the problem in my case. Hope it helps.
This happened to me just now when I had a website set up in IIS for mydomain.com, and set my project's start up url (Local IIS) to mydomain.com, and then launched the project before remembering to add a record in the host files for the domain:
127.0.0.1 mydomain.com
This got me for a good hour before I remembered I never set the record. Adding the record fixed it right away.
Windows 7 x64, VS 2012
In my case, the Remote Debugging Monitor component was installed and the app was clearly configured to debug locally in settings. This was a WinForms app upgraded from VS 2008, .NET 3.5.
Turns out it was the Windows Firewall. By directly running:
C:\Program Files (x86)\Microsoft Visual Studio 11.0\Common7\IDE\Remote Debugger\x64\msvsmon.exe
A firewall dialog appeared where I could allow msvsmon.exe to run. After a VS 2012 re-start, debugging (locally) was fine!
Ensure you have Local Machine selected in this drop-down menu:
Windows 7 x64, VS 2012, VB.NET
I fixed it like this:-
Create a shortcut on your desktop to "C:\Program Files (x86)\Microsoft Visual Studio 11.0\Common7\IDE\Remote Debugger\x64\msvsmon.exe".
Right-click shortcut and select "Properties" from the dropdown menu. Select the "Compatibity" tab, tick "Run this program as administrator" and click OK
Create a shortcut on your desktop to "C:\Program Files (x86)\Microsoft Visual Studio 11.0\Common7\IDE\devenv.exe".
Right-click shortcut and select "Properties" from the dropdown menu. Select the "Compatibity" tab, tick "Run this program as administrator" and click OK.
To start VS2012:-
Double-click the msvsmon shortcut icon (that you created above, to launch msvsmon). Wait for the "Visual Studio Remote Debugging Monitor (Administrator)" window to display before continuing ...
Double-click the "Visual Studio 2012 Professional" shortcut icon (that you created above, to launch VS2012)
In VS2012, ensure standard toolbar is visible.
In VS2012, ensure "Solution Platforms" dropdown (on standard toolbar) is visible and set to "x86".
and debug now works (for me anyway) ...
However after 15 minutes or so, debug may stop working and you may get the msvsmon error again. If that happens, simply close VS2012 and msvsmon and then start again (from "To start VS2012:-" above) ...
Myself and several other developers have been trying to look for a solution for this problem for about 3/4 hours as Visual Studio crashed then this error would occur (twice in 2 days). I then suddenly (after a lot of debugging and trying other suggestions and headbanging) I somehow realised that the file which was highlighted had changed and when I was trying to debug was not the MVC app project, once I changed it to my project's one it then worked.
Hope this helps and saves people from hours of pain!
I also got this error, I usually run sites under a named user (which is also a database user) and forgot to set the Application Pool. (parliament's answer also helped me)
For me this worked in VS2013:
Save your work, close Visual Studio then reopen your project
I encountered this error as well.
The cause of mine was that I had accidentally emptied out the following property
Properties->Debugging->WorkingDirectory
Changing it to:
inherit from parent or project defaults
Solved the issue.
If you are using Microsoft's Azure, try attaching manually the debugger:
