unable to start windows service after installing using msi


I've created a windows service project. In the post build event, I am copying the output to outside one common directory along with one more project. I am generating a MSI using heat task to copy both directories inside MSI. I'm trying to start service after installation.

Both projects use serilog.configuration to load json file which has logger configuration.

If I install service with the help of installutil, service is installed successfully and starts afterwards perfectly. but when I try to install using MSI, I get below error and installation never finishes.

Service cannot be started. System.IO.FileLoadException: Could not load file or assembly 'Microsoft.Extensions.Configuration.Abstractions, Version=, Culture=neutral, PublicKeyToken=adb9793829ddae60' or one of its dependencies. The located assembly's manifest definition does not match the assembly reference. (Exception from HRESULT: 0x80131040)
File name: 'Microsoft.Extensions.Configuration.Abstractions, Version=, Culture=neutral, PublicKeyToken=adb9793829ddae60'
   at Hive.WindowsAgent.Service.HiveAgentService.OnStart(String[] args)
   at System.ServiceProcess.ServiceBase.ServiceQueuedMainCallback(Object state)

WRN: Assembly binding logging is turned OFF.
To enable assembly bind failure logging, set the registry value [HKLM\Software\Microsoft\Fusion!EnableLog] (DWORD) to 1.
Note: There is some performance penalty associated with assembly bind failure logging.
To turn this feature off, remove the registry value [HKLM\Software\Microsoft\Fusion!EnableLog].

I checked nuget package, windows service has Microsoft.Extensions.Configuration.Abstraction v3.1.5 included. And it fails only with MSI.

my wix file:

        <ServiceControl Id="StartStopService"
                        Wait="yes" />

What am I missing?

P.S. Let me know if anymore information is needed

In your csproj file add:


there's an issue with auto-generated binding redirects.

This should force MSBuild to create / update a YourProject.dll.config file containing the necessary binding redirects.

It was the stupidest thing i could think of. Fortunately I had received a lot of help from Kevin and Alex on .net slack group.

All I was missing exe extension in <File Id="$(var.ServiceName)" Name="$(var.ServiceName)" Source="$(var.ProductPath)" KeyPath="yes" />

Ultimately the line should be

<File Id="$(var.ServiceName)" Name="$(var.ServiceName).exe" Source="$(var.ProductPath)" KeyPath="yes" />
