This exception was originally thrown at this call stack:

EntryLog.EntryLog.LogWarning(string) in EntryLog.cs
EntryLogConsoleTest.Program.Main(string[]) in Program.cs
The exception is coming about from the following lines;
string filePath = System.IO.Path.Combine(EntryLog.LogPath.AbsolutePath, currentTimeFilename + " - " + $"{foldername}.log");
var fileStreamer = new FileStream(filePath, FileMode.OpenOrCreate, FileAccess.Write);
var streamWriter = new StreamWriter(fileStreamer);
The LogPath is obtained by this method;
LogPath = new Uri(Path.GetDirectoryName(System.Reflection.Assembly.GetExecutingAssembly().Location));
I have tried all manner of debugging but it always throws the above exception at StreamWriter. Kindly assist me in resolving this. I'm using 4.5.2 .net Framework
FILE PATH
The file path in question is this;
C:\Users\JNyingi\source\repos\EntryLogConsoleTest\EntryLogConsoleTest\bin\Debug
CURRENT TIME AND FOLDER NAME
string currentTimeFilename = DateTime.Now.ToString("yyyy-MM-dd HH:mm");
string foldername = "Log"

the problem is the : in your filename
string currentTimeFilename = DateTime.Now.ToString("yyyy-MM-dd HH:mm");
^
Change it to - or _ or even a . for example and the error disappears
string currentTimeFilename = DateTime.Now.ToString("yyyy-MM-dd HH_mm");

Using ILSpy you can find that the code of the method EmulateFileIOPermissionChecks (which raises the NotSupportedException) is:
internal static void EmulateFileIOPermissionChecks(string fullPath)
{
if (AppContextSwitches.UseLegacyPathHandling || !PathInternal.IsDevice(fullPath))
{
if (PathInternal.HasWildCardCharacters(fullPath))
{
throw new ArgumentException(Environment.GetResourceString("Argument_InvalidPathChars"));
}
if (PathInternal.HasInvalidVolumeSeparator(fullPath))
{
throw new NotSupportedException(Environment.GetResourceString("Argument_PathFormatNotSupported"));
}
}
}
So your path contains invalid chars.
EDIT
If in your settings hours - minutes separator is a colon (see your datetime formatted string), please consider that ':' cannot be used in a path, but after driver letter.

C# change console encoding error (bad descriptor)

Today i run Visual Studio and open my project, that i not opened about 5 months.
And running test (it was be OK) invoke IOException with additional information: "Bad descriptor".
It was in this line:
var defaultConsoleEncoding = Console.InputEncoding;
Console.InputEncoding = TryGetEncoding("UTF-8"); // <--- There is error
...
public static Encoding TryGetEncoding(string encoding)
{
try
{
return Encoding.GetEncoding(encoding);
}
catch (ArgumentException)
{
Logger.WarnAndPrint($"Can't using {encoding} encoding. Fallback to utf-8");
return Encoding.UTF8;
}
}
All my tests were OK, but now all fails with that error. I never chage code in project. And i try many encodings - nothing work.
What's the problem?
P.S. This is stack trace

InstallShield: Managed code threw an unhandled exception.
This is the error I receive after doing all that is mentioned in the screenshots below and doing some R&D. The directory mentioned "C:\Program Files (x86)\\.config" exists when the encryption custiom action is being called but it throws an exception.

Yes, it can be done with following steps:
1- write your required functionality in c# installer class (make sure your are using installer class)
2- Compile and add your dll into installshield (recomended create a separate component for this dll)
3- Select component view -> select above component and go to .Net settings section, set the ".Net Installer class" to true. Set the ".net installer class parameters"
Parameters are passed as key/value pair e.g
/targetDirectory="[INSTALLDIR]\"
All steps are same, just added screenshots.
Create a dll with an installer class and your encrypt/decrypt class.
Add dll and config file to component(above mentioned), if config file is already added to some other component then its fine. no need to add again.
I have added and retrieved INSTALLDIR variable as argument which is predefined. if you want to receive some input from user (from some custom textboxes) then you will need to define your own variables to store and pass values as arguments.
Creating dll with installer class and your requred logic for other task
Creating component and adding files
Mark the dll as installer class and pass arguments
Here goes installer class:

using System.IO;

using System.ComponentModel;
using System.Configuration.Install;
using System.Collections.Generic;

try
{
//For testing purpose only.. work only in debug mode when pdb files are deployed as well.
//Debugger.Break();
installationDirectory = Context.Parameters["INSTALLDIR"];
//I believe, the config file must be located in the installation directory if so, then use the following way to compute path
string configFilePath = Path.Combine(installationDirectory, "myConfigFile.config");
EncrptionHelper.SetValue(configFilePath, "testKey", "testValue");
}
catch (Exception ex)
{
System.Diagnostics.Debug.WriteLine(ex.Message);

}
}

I think installshield cannot (or need extra work) for read your assemblies, but you can run simple console application which consume your assemblies from installscript and passing parameter from installshield.
Create simple console application
Include console application on Support Files
Copy to installation folder or assemblies location, so console application can access your assemblies
Launch from installscript using launchappandwait
If consoleapp.exe not use anymore, just delete it.

I'm getting an odd MissingManifestResourceException

I have a solution with several projects, a main project, a globalization project and a test project.
When code in the main project retreives a message from the Messages.de.resx file of the globalization project everything works fine.
But when I copy the same code to the test project, I get a MissingManifestResourceException telling me no resources were found for the specified or neutral culture:

Normally, the code works just using the .resx file and even using resgen to compile it into a .resources file changes nothing.
I thought it might have to do with the ResourceManager or the specified Assembly, but I could not see any difference between the call from the main project and the call from the test project.
This is the code:
public static class UserMessage
{
private static ResourceManager _resourceManager;
static UserMessage()
{
string baseName = Assembly.GetAssembly(typeof(UserMessage)).GetName().Name + ".Messages.de";
Console.WriteLine(baseName);

//using the GetString overload with or without CultureInfo paramter makes no difference
msg = _resourceManager.GetString(msgID, new CultureInfo(Properties.DefaultLanguage));

Thanks!

I've had the same error - it suddenly occurred even though the application had been running for a while.
It helped to set the Thread.CurrentThread.CurrentUICulture before getting the resource.
Try the following or something similar:
Thread.CurrentThread.CurrentUICulture = CultureInfo.GetCultureInfo("de-DE");
msg = _resourceManager.GetString(msgID);
