Run a dll of application through C#

I am trying to call a dll file that accepts command line arguments through c# code.

when I tried directly from cmd window it works but if I try to call this from C# it is showing following error : "No application is associated with the specified file for this operation"

sample cmd command - C:\Users\user name\source\repos\addconsole\addconsole\bin\Debug\netcoreapp3.1>dotnet AddConsole.dll 1 2 3

 static void Main(string[] args)
 {
   var proc1 = new ProcessStartInfo();
   proc1.UseShellExecute = true;
   proc1.WorkingDirectory = @"C:\Users\user name\source\repos\addconsole\addconsole\bin\Debug\netcoreapp3.1";
   proc1.FileName = @"addconsole.dll";
   proc1.Arguments = "1 2 3";
   Process.Start(proc1);
 }

Need help on this.please note there is no exe file this application that needs to be called has a dll file which has main function that executes the operation.

You actually need to call dotnet.exe and provide the relevant arguments. So set the FileName to dotnet and the rest as arguments.

var proc1 = new ProcessStartInfo();
proc1.UseShellExecute = true;
proc1.WorkingDirectory = @"C:\Users\user name\source\repos\addconsole\addconsole\bin\Debug\netcoreapp3.1";
proc1.Arguments = "\"addconsole.dll\" 1 2 3";
proc1.FileName = "dotnet.exe";
Process.Start(proc1);
