How to install an ASP Core .NET 6 as windows service?

[ComptonAlvaro]

This has relation with this issue: dotnet/aspnetcore#43547, but there I was thiking about gRPC and I considerate it is better don't mix the two quiestions.

In this case I just created an ASP Core project. I followed this steps:

1.- Create a ASP Core with the template of VS2022.
2.- Import the package Microsoft.Extensions.Hosting
3.- Import the package Microsoft.Extensions.Hosting.WebServices
4.- I use this code:

File.AppendAllText("LogManual.txt", DateTime.Now + ": Iniciado");


var builder = WebApplication.CreateBuilder(args);

// Add services to the container.
builder.Services.AddRazorPages();


//Para poder alojar ASP como servicio de windows.
builder.Host.UseWindowsService();


var app = builder.Build();

// Configure the HTTP request pipeline.
if (!app.Environment.IsDevelopment())
{
    app.UseExceptionHandler("/Error");
    // The default HSTS value is 30 days. You may want to change this for production scenarios, see https://aka.ms/aspnetcore-hsts.
    app.UseHsts();
}

app.UseHttpsRedirection();
app.UseStaticFiles();

app.UseRouting();

app.UseAuthorization();

app.MapRazorPages();

app.Run();

When I debug this project, it works and open the webpage in the internet browser.

Then i try to install the service, I use this cmd script:

REM ECHO %~dp0
REM ECHO %~dp0..\
FOR %%A IN ("%~dp0.") DO SET parent=%%~dpA
REM esto quitará el último carácter, que es la barra inclinada.
REM set parent=%parent:~0,-1%%
SET ruta="D:\AspTest\bin\Debug\net6.0\AspTest.exe"
echo %ruta%

sc.exe create AspTest binpath="%ruta%" start=auto displayname= "Test de ASP"
sc.exe start AspTest


pause

The service is installed, then I go to services and it is not running, so I try to start the service manually, but i get the error 1053.

If I go to the event viewer in windows, I find 2 events:

• ID 7009: timeout (30000ms)
• ID 7000: The service doesn't response on time.

I have read the documentation in this link: https://docs.microsoft.com/en-us/aspnet/core/fundamentals/host/hosted-services?view=aspnetcore-6.0&tabs=visual-studio.

How should I created the ASP Core to can install as windows service? Really my idea it is to host a gRPC service, but I try this example to start with the most simple example that I could try.

Thanks.

I oculd solve it if in the first line of my pogram.cs I set the CurrentDirectory of the enviroment:

Environment.CurrentDirectory = Path.GetDirectoryName(Assembly.GetExecutingAssembly().Location);

It is because the user that run the service, System, doesn't have permissions to write in c:\windows\system32, that is the default directory of the services.

We have fixed this in 7.0 with #68580 and dotnet/docs#29945. See the documentation on this change at https://docs.microsoft.com/en-us/dotnet/core/compatibility/extensions/7.0/contentrootpath-hosted-app.

I'm going to close this since the fix has been made in the latest version. You can continue to use the above workaround until you upgrade to 7.0.

Thanks, it is good to know it will be fixed in the next version.
