Csharp app only work on my pc Visual Studio 2019

If I run the App on my pc from visual studio or from outside of VS, after compiling with the installer package and installing it, in my pc works ok but if I install it on other pc, then I get this error and don't start
"Unhandled exception has occurred in your application. If you click Continue, the application will ignore this error and attempt to continue. If you click Quit, the application will close immediately
Could not load file or assembly "filename.dll" or one of its dependencies. The specified module could not be found."
Note: "filename.dll" is located in to the main folder with app.exe file after installation
Error From Windows Event Viewer
Application: myapp.exe Framework Version: v4.0.30319 Description: The process was terminated due to an unhandled exception.

any ideas about that?

I found the solution, some dll files are missing that this one uses, I know which ones are used with the dumpbin /imports filename.dll command, so I downloaded all those and it worked

UWP resources not found

I have an UWP application which is working fine on various machines but on one particular machine, it is crashing silently.
When I debugged the installed app through visual studio I figured out that it is not getting the resources on the XAML file e.g
{ThemeResource ComboBoxDropdownContentMargin}
{Binding TemplateSettings.DropDownContentMinWidth, RelativeSource={RelativeSource Mode=TemplatedParent}}
The Output window is showing the following exception
Exception thrown at 0x751641E8 (KernelBase.dll) in
myapplicationnamechanged

As per this MSDN documentation ComboBoxDropdownContentMargin was made availalbe from Windows 10, Version 1511 (Windows SDK version 10.0.10586.0).
So if you are running your App which has Version lower than the supported version, in that case, it will throw an exception.

Publish umbraco site on IIS

i'm stuck.
I upload my umbraco 7.1 site which i develop on visual studio 2012 thorough FTP to my server.
I created an Application Pool which work with .net framework 4.0.30319.
I start the site in the IIS and try to check it in the browser and i got this error:
Could not load file or assembly 'UrlRewritingNet.UrlRewriter' or one
of its dependencies. The system cannot find the file specified.
Description: An unhandled exception occurred during the execution of

[HKLM\Software\Microsoft\Fusion!EnableLog].
Please help me to understand what should i do.
thanks,
Ido.

Seems like your Visual studio has not uploaded all DLL's from the BIN directory.
I would try to check using a FTP client whether all DLL's (in the bin folder) are uploaded.

Windows Store App minidump crash debug issue with windbg

I submitted an update of my app to the windows store and it failed certification because of crash.
I received a triagedump.dmp file from them.
I opened the file with windbg and loaded sos and mscordacwks dll's and typed !analyze -v
I got
MANAGED_OBJECT_NAME: SYSTEM.NULLREFERENCEEXCEPTION
MANAGED_STACK_COMMAND: !pe 2931590
So i did !pe 2931590
Exception object: 02931590
Exception type: System.NullReferenceException

I don't know the UNKNOWN part of YoutubeMP3Converter_ni!UNKNOWN+0x9a
So i don't have the YoutubeMP3Converter.ni.exe file they used.
I also tried to use my YoutubeMP3Converter.exe but he said that there is a mismatch with the memory image header en the file image header.
So what are my options here?
- Can I create the .ni (native image) version of my exe.
- How can I get the correct YoutubeMP3Converter.exe? Do I have to take it out the appxupload package?
- Can I create my windows store app with options if it crashes that it creates a full dump instead of a triagedump (minidump) ?
I know what the exception is but I don't know where it happens as I don't have the full stacktrace :(.
UPDATE - found it
You can find the matching .exe to load as img in windbg in AppxUpload package which is send when you upload your app to the store. Then WinDbg has enough info to show the correct symbols which will lead you to what class/method the exception was thrown.
