Trying to convert windows exe for chrome extension to dot net core 2 - google-chrome-extension

Question

I have heard that Dot net core only generates dll file and the only way to run them is using the command
dotnet myapp.dll
I have a chrome extension and i am trying to do some operations . For example, on chrome extension i enter two numbers and then click send button. this triggers the native messaging and a windows executable/dll is called which takes these 2 numbers as stdin and returns the sum as stdout which would be displayed on chrome extension .
Earlier it was an exe file which was working fine. Now i have migrated the code to dotnet core 2.0 . My unit tests work fine but the dll is unable to execute . i dont see any logs as well . my best guess is that the dll is not getting called at all. somehow i have no idea how to check if the app is getting called from chrome extension
{
"name": "myapp",
"description": "myapp",
"path": "C:\\Program Files (x86)\\myapp.dll",
"type": "stdio",
"allowed_origins": [
"chrome-extension://lpfjfcebobk**************/"
]
}
UPDATE -1
I was able to solve this by creating a bat file which in turn calls the dll file by the following command
dotnet my_app.dll
Also my bat file looks like this
#echo off

dotnet "my_app.dll" %*
and my app_manifest looks like this
{
"name": "myapp",
"description": "myapp",
"path": "C:\\Program Files (x86)\\myapp.bat",
"type": "stdio",
"allowed_origins": [
"chrome-extension://lpfjfcebobk**************/"
]
}
