How to get the current solution name from a Visual Studio Package project?

Question

I created a Visual Studio Package project with a custom menu I would like to add to Visual Studio (2013).

I'm trying to get the current solution name/directory in run time.

I've tried this solution:

DTE dte = (DTE)GetService(typeof(DTE));
string solutionDir = System.IO.Path.GetDirectoryName(dte.Solution.FullName);

but dte.Solution.FullName is always empty.

I though it is related to the fact that i'm running in debug mode and a new instance of Visual Studio is created for this purpose, but it happened also when I installed my extension and ran it from Visual Studio as I ran any menu.

Any ideas what i'm missing?

Thanks

P.S. the solution I used is taken from here:

You can achieve it by finding the .sln file up the directory tree from your executing assembly:

public static class FileUtils
{
    public static string GetAssemblyFileName() => GetAssemblyPath().Split(@"\").Last();
    public static string GetAssemblyDir() => Path.GetDirectoryName(GetAssemblyPath());
    public static string GetAssemblyPath() => Assembly.GetExecutingAssembly().Location;
    public static string GetSolutionFileName() => GetSolutionPath().Split(@"\").Last();
    public static string GetSolutionDir() => Directory.GetParent(GetSolutionPath()).FullName;
    public static string GetSolutionPath()
    {
        var currentDirPath = GetAssemblyDir();
        while (currentDirPath != null)
        {
            var fileInCurrentDir = Directory.GetFiles(currentDirPath).Select(f => f.Split(@"\").Last()).ToArray();
            var solutionFileName = fileInCurrentDir.SingleOrDefault(f => f.EndsWith(".sln", StringComparison.InvariantCultureIgnoreCase));
            if (solutionFileName != null)
                return Path.Combine(currentDirPath, solutionFileName);

            currentDirPath = Directory.GetParent(currentDirPath)?.FullName;
        }

        throw new FileNotFoundException("Cannot find solution file path");
    }
}

Results:

FileUtils.GetAssemblyFileName();
"CommonLibCore.dll"
FileUtils.GetAssemblyPath();
"G:\My Files\Programming\CSharp\Projects\MyAssemblyMVC\MyAssemblyConsole\bin\Debug\netcoreapp3.1\CommonLibCore.dll"
FileUtils.GetAssemblyDir();
"G:\My Files\Programming\CSharp\Projects\MyAssemblyMVC\MyAssemblyConsole\bin\Debug\netcoreapp3.1"
FileUtils.GetSolutionFileName();
"MyAssemblyMVC.sln"
FileUtils.GetSolutionPath();
"G:\My Files\Programming\CSharp\Projects\MyAssemblyMVC\MyAssemblyMVC.sln"
FileUtils.GetSolutionDir();
"G:\My Files\Programming\CSharp\Projects\MyAssemblyMVC"

I think this might be best solution. As i see it there might be other solutions 'hidden' for Visual Studio, thus search might fail - however if youre doing solutions inside solutions you are better of using projects anyways and have a flaw in you architecture... +1 — mschr, Feb 13 '23 at 08:00

Try this:

var solutionName = Path.GetFileName(System.Diagnostics.Process.GetCurrentProcess().MainModule.FileName);

You need to be using System.IO and System.Diagnostics. There also might be some file extensions at the end of solutionName that you will need to trim.

This gives me the path to https://i.imgur.com/S8wddje.png And its not what OP wanted. – Steve Johnson Mar 18 '18 at 09:32
This gives me "iisexpress.exe", not what's asked for. – Kon Feb 16 '23 at 19:19
