Unable to Publish Project #963
Description
Whenever I try to publish an ASP.NET project following the provided steps in the wiki, the build fails with the following exception when running the electron-builder:
ENOENT: no such file or directory, stat '<path_to_solution>\BlazorApp1\BlazorApp1\obj\Release\net10.0\win-x64\PubTmp\Out\node_modules\electron-host-hook' failedTask=build stackTrace=Error: ENOENT: no such file or directory, stat '<path_to_solution>\BlazorApp1\BlazorApp1\obj\Release\net10.0\win-x64\PubTmp\Out\node_modules\electron-host-hook'
- NuGet Version: 0.2.0
- Electron Version: 30.4.0 (not specified in
.csproj) - Electron Builder Version: 26.0.12 (not specified in
.csproj) - Framework: net10.0
- Target: win-x64 (specified via publish profile)
- IDE: Visual Studio 2026 18.0.1
Steps to Reproduce:
- Create a new Blazor Web App, targeting
net10.0 - Add
ElectronNET.CoreandElectronNET.Core.AspNetversion 0.2.0 as NuGet packages - Add
builder.UseElectron(args, ElectronAppReady);to the builder call and the following method for creating the window:
private static async Task ElectronAppReady()
{
var browserWindow = await Electron.WindowManager.CreateWindowAsync(new BrowserWindowOptions {Show = false});
browserWindow.OnReadyToShow += () => browserWindow.Show();
}- Create a publish profile under
Properties/PublishProfile(in this case aswin-x64.pubxml) with the following content:
<?xml version="1.0" encoding="utf-8"?>
<Project>
<PropertyGroup>
<Configuration>Release</Configuration>
<Platform>Any CPU</Platform>
<PublishDir>publish\$(Configuration)\$(TargetFramework)\$(RuntimeIdentifier)\</PublishDir>
<PublishProtocol>FileSystem</PublishProtocol>
<TargetFramework>net10.0</TargetFramework>
<RuntimeIdentifier>win-x64</RuntimeIdentifier>
<SelfContained>true</SelfContained>
<PublishSingleFile>false</PublishSingleFile>
</PropertyGroup>
</Project>- Publish the project using the Visual Studio interface
I also tried specifying a specific Electron and electron-builder version in the .csproj file without success. Normal debug/release builds and running it succeed without issues. I tried following the provided wiki pages as close as possible. If I'm doing something wrong, please correct me.
Please note, that this happened in a newly created blank project. I initially ran into this same issue when reworking a more complex project (several package and project dependencies) to use this package. It might be a related issue but publishing that more complex project also DELETED ALL SOURCE FILES within that project directory. Luckily, I had all relevant changes committed or staged.

Try the latest preview version of 0.3.0.
AeonSake commentedon Dec 7, 2025
Tried with
0.3.0-pre.314which now also deletes the entire project directory content on publish. Seems like I must have used a pre-release package in the more complex project too.The error now is:

@AeonSake - Please take a look at this: #946 and make sure that your project fulfills all those (not yet implemented) conditions.
AeonSake commentedon Dec 7, 2025
@softworkz both projects fulfill all those checks; this also happens in a brand new blank project.

Can you provide a sample project? (also in-private, if you prefer)
AeonSake commentedon Dec 7, 2025
Sure; here is a default Blazor Web App for net10.0 (including the default sample pages). I only added the packages, builder calls, and the publish profile from above.
If you use any 0.3.0 version, the project directory will be wiped. If you use 0.2.0 it will result in the error from above.
BlazorApp1.zip

@AeonSake
I have
There were no deletions and it's working fine:
softworkz commentedon Dec 7, 2025
Ah sorry - you said "on publish". I see it now.
The reason why this happens is that you are using the wrong publish profile (copied from somewhere else?)
When you use the publish wizard to publish the project, everything will be working fine.
Example:
Background: Folder publishing for ASP.Net projects is a whole different implementation, even though it looks like it was the same. The pubxml files must not be mixed between ASP.Net and other projects (like cosole app).
AeonSake commentedon Dec 7, 2025
Oh, interesting... I was following the wiki which listed my initial publish profile. Thanks for clarifying. It would probably be a good idea to update the wiki pages to have the correct publishing instructions.
softworkz commentedon Dec 7, 2025
Ohhh ouch - that was my fault!
I'm very sorry about that!
AeonSake commentedon Dec 7, 2025
All good, glad it was solved regardless.
AeonSake commentedon Dec 7, 2025
So publishing the example project now works perfectly, just not with the more complex project. But that might just be on my end. I'll try tweaking different things to hopefully get it to work. I think you can close the issue, unless you want to keep it around until the wiki is updated.

Let us know when you got any more questions!
