Trying to return a bool from async function but failed

[citystrawman]

Hi, I am using CliWrap to run a series of exe.
I firstly use CliWrap to formulate the functions that runs each of the exe as follows:

private static async Task<BufferedCommandResult> RunStep1( ) {
    var result1 = await Cli.Wrap(executable1Path)
    .WithWorkingDirectory(cwd)
    .WithArguments(args => args
    .Add("arg1")
    .Add("opt1")
    .Add("arg2")
    .Add("opt2")
).ExecuteBufferedAsync(cts.Token);
}

private static async Task<BufferedCommandResult> RunStep2( ) {
    var result1 = await Cli.Wrap(executable2Path)
    .WithWorkingDirectory(cwd)
    .WithArguments(args => args
    .Add("arg1")
    .Add("opt1")
    .Add("arg2")
    .Add("opt2")
).ExecuteBufferedAsync(cts.Token);

......
}

Then I combine these single steps into one:

public static async void RunPipeline( ) {
            try
            {
                result = await RunStep1();
            }
            catch (OperationCanceledException ex)
            {
#if DEBUG                
                MessageBox.Show("Step 1 error: " + ex.Message.ToString());
#endif
                throw ex;
            }

            try
            {
                result = await RunStep2();
            }
            catch (OperationCanceledException ex)
            {
#if DEBUG                
                MessageBox.Show("Step 2 error: " + ex.Message.ToString());
#endif
                throw ex;
            }

           ......
}

and this RunPipeline function could run the whole process fine.

Then, I want to return a bool from the RunPipeline function, so I edited it as follows:

public static async Task<bool> RunPipelineBool( ) {
            try
            {
                result = await RunStep1();
            }
            catch (OperationCanceledException ex)
            {
#if DEBUG                
                MessageBox.Show("Step 1 error: " + ex.Message.ToString());
#endif
                throw ex;
            }

            try
            {
                result = await RunStep2();
            }
            catch (OperationCanceledException ex)
            {
#if DEBUG                
                MessageBox.Show("Step 2 error: " + ex.Message.ToString());
#endif
                throw ex;
            }


            if(some condition mathes) {
            return false;
            } else {
            return true;
            }
           ......
}

and I tried to get the result as follows:

Task<bool> task = RunPipelineBool();
bool isSuccess = task.Result;
if (isSuccess ) {
......
} else {
......
}

However, when I run the above code, the program stucks , but it does not report any error (by setting the breakpoint I can see that the program starts running the first exe, but then it stucks and does not report any error). I am wondering if I made some mistake in getting the bool. I appreciate if anyone could point it out. Thanks!

You should do var isSuccess = await RunPipelineBool().
