Hello
Unfortunately there is no such template atm.
Assuming you need to run your application as a Windows Service you need to do the following steps:
Microsoft.Extensions.Hosting.WindowsServices
package and replace UseConsoleLifetime
call with UseWindowsService
in the Program.cs file.Unfortunately the Microsoft.Extensions.Hosting.WindowsServices
package does not provide its own installer so the standard Windows Service installer should be used:
sc create [Service_Name] BinPath=[full_path_to_the_server_app_exe_file]
Also several other commands are available that allow to start, stop or delete the Windows Service:
sc start [Service_Name]
sc stop [Service_Name]
sc delete [Service_Name]
Regards
I followed the instructions and think the server is basically set up but here are some questions regarding this:
From docs:
For example to turn the application into a Windows Service one would need to reference the Microsoft.Extensions.Hosting.WindowsServices package and to replace the
UseConsoleLifetime
method call with theUseWindowsService
method call.
You need to either check app startup command line parameters and call UseConsoleLifetime
orUseWindowsService
based on startup params (like --console
for console mode) or just split the app into 3 projects:
Use**
call. I.e. this part of the code: return Host.CreateDefaultBuilder(args)
.ConfigureServices((hostContext, services) =>
{
})
.UseApplicationServer(configuration =>
{
})
.UseNetworkServer(server =>
{
})
Use*
method.Have you ever installed a Trial with the same version # on that host? If so, then you need to delete obj
and bin
folders if your project app and then clear the NuGet cache in the VS settings. Then VS will redownload NuGet packages into its cache, replacing Trial packages with Full ones
Regards
Sorry, I missed that in the documentation. For my purposes the following is sufficient:
public static void Main(string[] args)
{
IHostBuilder builder = CreateHostBuilder(args);
if (System.Diagnostics.Debugger.IsAttached)
{
builder = builder.UseConsoleLifetime();
}
else
{
builder = builder.UseWindowsService();
}
IHost host = builder.Build();
host.Run();
}
I downloaded and installed the software from my product downloads page. I was prompted to enter my user name and password and the license downloaded. Yet when I run the client application I get the message in the image below. I don’t see a license.licx file anywhere but the .NET 6 project is so different I don’t know if this is how the licensing works anymore.
Latest RO/DXA no longer uses the .licx system, as its not supported by .NET Core. instead, we now (as for the other platforms) ship different versions of the .dlls for Trial vs Full.
If you’re getting the trial message, that means you are accidentally still building agianst the Trial version .dlls. Can you check your build log and see where the RO/DA .dll(s) are being referenced from? Also maybe, JIC force a rebuild, in case that ws cached.
Are you using Elements or Visual C#?
Visual Studio Enterprise 2022 (17.1.2)
Visual C# (not Elements)
Unfortunately I have no idea where to find the build log… aside from the Output Window.
I can tell you that the Template created this project initially as .NET Core 3.1 and I changed it to .NET 6.
Then I had to add the NuGet packages to both the client and the server application to get it to build. I also had to add the Microsoft SQL Server and Microsoft Hosting extensions.
If I drill down into the dependencies far enough I see:
C:\Users\my name\.nuget\packages\remobjects.sdk\10.0.0.1537\lib\netcoreapp3.1\RemObjects.SDK.dll
C:\Users\my name\.nuget\packages\remobjects.sdk\10.0.0.1537\lib\netcoreapp3.1\RemObjects.SDK.ZeroConf.dll
C:\Users\my name\.nuget\packages\remobjects.sdk.server\10.0.0.1537\lib\netcoreapp3.1\RemObjects.SDK.Server.dll
Have you ever installed Trial version of Data Abstract with the same version?
If so, then you have to clean the NuGet package cache and then readd the dependencies.
Otherwise NuGet and MSBUIL will take dependencies from internal cache, thus using the Trial version.
Regards
No, I didn’t have a reason to as I own the product. I downloaded from my product downloads and when prompted I entered my login credentials to download my license.
Just for giggles I looked up how to clear the cache and reinstalled the NuGet packages. I’m still getting the warning that it is a trial version.
Yes, found the case why this message is triggered and fixed it.
You need to either wait for the next official build or drop a mail to support@ so we’ll send you a new build once it is available.
Sorry for the inconvenience.
No worries. I am just learning Data Abstract and I’m not in a hurry.
I’ve uploaded the latest version of DA to your Personal Downloads JIC, anyways.
