✅ WPF application doesn't boot when packed to single file

Hello, I made a program in WPF, and in the publish settings I enabled "Produce single file", but the output .exe crashes before the window even shows up. There is an error in the event viewer, but I'm not exactly sure what to make of it (https://pastebin.com/85J3ZzDL). Here are my publish settings:

string strExeFilePath = System.Reflection.Assembly.GetExecutingAssembly().Location; i dont get why this is making it crash thank you or the response, btw

Buddy•9mo ago

use ~~AppDomain.CurrentDomain.BaseDirectory~~ AppContext.BaseDirectory That might work instead of using GetExecutingAssembly

brownieOP•9mo ago

oh shit its working now, thank you so much i did this:

c#
// Sets current working directory to the .exe path
// string strExeFilePath = System.Reflection.Assembly.GetExecutingAssembly().Location;
string workingDir = Environment.CurrentDirectory;
Directory.SetCurrentDirectory(workingDir);

c#
// Sets current working directory to the .exe path
// string strExeFilePath = System.Reflection.Assembly.GetExecutingAssembly().Location;
string workingDir = Environment.CurrentDirectory;
Directory.SetCurrentDirectory(workingDir);

christ why is the executeable so fat

Buddy•9mo ago

Because the runtime is embedded within the application You can decide not to, but that would also mean requiring the user to install the runtime You can turn it off by not using self-contained

brownieOP•9mo ago

yeahh also what i did doesnt seem to have worked the application starts now but theres a problem basically when my program starts it checks to see if some required binaries exist in the working directory, and if they dont, then to download them

Buddy•9mo ago

Don't use Environment.CurrentDirectory* Use what I mentioned

brownieOP•9mo ago

ah ok

c#
string workingDir = AppDomain.CurrentDomain.BaseDirectory;

c#
string workingDir = AppDomain.CurrentDomain.BaseDirectory;

like this?

Buddy•9mo ago

Actually, it's better if you use AppContext.BaseDirectory

brownieOP•9mo ago

same issue came up again with this

Buddy•9mo ago

I meant the other

brownieOP•9mo ago

yeah im trying that now

Buddy•9mo ago

it should not give you null

brownieOP•9mo ago

same issue again gimme a second

c#
// Sets current working directory to the .exe path
// string strExeFilePath = System.Reflection.Assembly.GetExecutingAssembly().Location;
string workingDir = AppContext.BaseDirectory;

// Check if ffmpeg directory exists in working directory
bool ffmpegDirExists = Directory.Exists("ffmpeg");

if (!ffmpegDirExists)
{
    Directory.CreateDirectory("ffmpeg");
}

// Check if tmp directory exists
bool tmpDirExists = Directory.Exists("tmp");

if (!tmpDirExists)
{
    Directory.CreateDirectory("tmp");
}

c#
// Sets current working directory to the .exe path
// string strExeFilePath = System.Reflection.Assembly.GetExecutingAssembly().Location;
string workingDir = AppContext.BaseDirectory;

// Check if ffmpeg directory exists in working directory
bool ffmpegDirExists = Directory.Exists("ffmpeg");

if (!ffmpegDirExists)
{
    Directory.CreateDirectory("ffmpeg");
}

// Check if tmp directory exists
bool tmpDirExists = Directory.Exists("tmp");

if (!tmpDirExists)
{
    Directory.CreateDirectory("tmp");
}

this is the code for checking if the binaries i need exist does Directory.Exists check in the working directory? hold on i think i had a brainfart its working now its 11:30pm gimme a break 😭 thank you so much for your help
