This might help you TL;DR: your code is ill-formed. Your compiler accepts some ill-formed parts of your code as an extension, but that in turn triggers other ill-formed constructs.
code :
const int g = 20;
int g;
bool MatriceA[g][g];

public bool method Cannot implicitly convert type `bool' to `void'

This might help you Your lambda is an enclosed method, so the context for the return statement is the lambda method, not unlockAchievement.
You'll probably want to refactor your code to use a callback, i.e. something like this:
code :
public void unlockAchievement(string achievementName, string achievementID, Action<bool> callback) {
    if(loggedIn == true) {
        Social.ReportProgress(achievementID, 100.0f, (bool success) => {
            callback(success);
        });
    }
    else callback(false);
}
how to convert bool array in one byte and later convert back in bool array

help you fix your problem Here's how I would implement this.
To convert the bool[] to a byte:
code :
private static byte ConvertBoolArrayToByte(bool[] source)
{
    byte result = 0;
    // This assumes the array never contains more than 8 elements!
    int index = 8 - source.Length;

    // Loop through the array
    foreach (bool b in source)
    {
        // if the element is 'true' set the bit at that position
        if (b)
            result |= (byte)(1 << (7 - index));

        index++;
    }

    return result;
}
private static bool[] ConvertByteToBoolArray(byte b)
{
    // prepare the return result
    bool[] result = new bool[8];

    // check each bit in the byte. if 1 set to true, if 0 set to false
    for (int i = 0; i < 8; i++)
        result[i] = (b & (1 << i)) == 0 ? false : true;

    // reverse the array
    Array.Reverse(result);

    return result;
}
Why does the compiler convert bool to integer and back to bool instead of returning the bool itself?

hope this fix your issue It is decompiled code, it is likely just a glitch of the decompiler.
code :
public enum ConnectionState
{
    Closed = 0,
    Open = 1,
    Opening = 2,
    OtherStuff = 3,
    AndSoOn = 4,
}

public bool IsOpen
{
    get
    {
        ConnectionState state;
        if (this.data != null)
        {
            state = ConnectionState.Open;
        }
        else
        {
            state = ConnectionState.Closed;
        }

        return state != ConnectionState.Closed;
    }
}

hop of those help? Statement 1. .Wait() has no return result. It is a void method, and therefore its result cannot be assigned to a variable.
You can use .Result which will wait until Task completes and return a result.
code :
// Both are applicable to simple Tasks:
bool isValid = MyValidationFunction(jsonData).Result;

// does that same as

var task = MyValidationFunction(jsonData);
task.Wait();  
bool isValid = task.Result;
// That's how you do it with async/await:
public async bool GetJsonAndValidate()
{
     string jsonData = GetJson();
     bool isValid = await MyValidationFunction(jsonData); 
}
Cannot convert from void to bool when trying to use an array in my reverse function

hop of those help? Just as the heading states, I am trying to reverse a float array with my own reverse function. , You are trying to print a function which returns type is void.
code :
Console.WriteLine(reverse(floatArr)); // cannot convert from void to bool -> this is correct error
reverse(floatArr);
foreach(var val in floatArr)
{
    Console.WriteLine(val);
}
Console.WriteLine(string.Join(",", floatArr));
