Не понимаю как запустить компилятор Roslyn в Докере Linux

Без докера все работало, писал вот так.

private static string CompileCs(string filePath)
        {
            var pc = new Process
            {
                StartInfo =
                {
                    Verb = "runas",
                    Arguments = $@"""C:\Program Files\dotnet\sdk\6.0.300\Roslyn\bincore\csc.dll"" -r:""C:\Program Files\dotnet\shared\Microsoft.NETCore.App\6.0.5\System.Private.CoreLib.dll"" -r:""C:\Program Files\dotnet\shared\Microsoft.NETCore.App\6.0.5\System.Console.dll"" -r:""C:\Program Files\dotnet\shared\Microsoft.NETCore.App\6.0.5\System.Runtime.dll"" -r:""C:\Program Files\dotnet\shared\Microsoft.NETCore.App\6.0.5\System.Runtime.InteropServices.RuntimeInformation.dll"" ""{filePath}.cs"" -out:""{filePath}.dll""",
                    FileName = "dotnet",
                    UseShellExecute = false,
                    RedirectStandardError = true
                }
            };
            pc.Start();
            pc.WaitForExit();
            var err = pc.StandardError.ReadToEnd();
            return err;
        }

С докером, поменял код на

        private static string CompileCs(string filePath)
        {
            var pc = new Process
            {
                StartInfo =
                {
                    Verb = "runas",
                    Arguments = @"usr/bin/dotnet/sdk/6.0.300/Roslyn/bincore/csc.dll",
                    FileName = "dotnet",
                    UseShellExecute = false,
                    RedirectStandardError = true,
                }
            };
            pc.Start();
            string err = pc.StandardError.ReadToEnd();
            pc.WaitForExit();
            return err;
        }

Но получаю ошибку:

Could not execute because the specified command or file was not found.\r\nPossible reasons for this include:\r\n * You misspelled a built-in dotnet command.\r\n * You intended to execute a .NET program, but dotnet-usr/bin/dotnet/sdk/6.0.300/Roslyn/bincore/csc.dll does not exist.\r\n * You intended to run a global tool, but a dotnet-prefixed executable with this name could not be found on the PATH.\n
