Description softlion 2017-06-01 09:14:04 UTC
I have this code:

1 NSData data = data.FromArray(new byte[] { 0x60, 0x03, .... });
2 var test = data[0];

While debugging, breakpoint set on line 2, in 'immediate window' (VS2015 debugger) i entered data[0], data, and data.ToArray(). 

Incorrect number or types of arguments
Parameter name: arguments

{<60030190 0000006f e575dc>}
    base: {Foundation.NSObject}
    Bytes: 0x17623c290
    ClassHandle: 0x1ac6cfb98
    Length: 11

    [0]: 0x60
    [1]: 0x03
    [2]: 0x01
    [3]: 0x90
    [4]: 0x00
    [5]: 0x00
    [6]: 0x00
    [7]: 0x6f
    [8]: 0xe5
    [9]: 0x75
    [10]: 0xdc

Expected result:


This may be a more deeper bug, any idea ?

Hello, can you provide the information about your development environment? Is that for VS on Windows?
Comment 2 Vincent Dondain [MSFT] 2017-07-10 16:32:07 UTC
We have not received the requested information. If you are still experiencing this issue please include your full build logs, crash reports (if any), test case (to reproduce) and all version information and re-open the bug report. Thanks!
Comment 3 softlion 2017-07-10 17:39:57 UTC
Yes this is VS for windows.
Comment 4 Vincent Dondain [MSFT] 2017-07-10 21:14:43 UTC
Please include your full build logs, crash reports (if any), test case (to reproduce) and all version information.

To get full build logs just set the log verbosity to diagnostic at the following locations:
- On Visual Studio for Mac: Preferences > Projects > Build
- On Visual Studio for Windows: Tools > Options > Projects and Solutions > Build and Run

On Visual Studio Windows you also want to add `-v -v -v -v` to the mtouch additional arguments by right-clicking the project in the solution explorer and selecting `Properties`.
Note: this is done automatically on Visual Studio for Mac when the log verbosity is set to diagnostic.

Easiest way to get exact version information:
- On Visual Studio for Mac: "Visual Studio" menu, "About Visual Studio" item, "Show Details" button.
- On Visual Studio for Windows: "Help menu", "About Microsoft Visual Studio" item.
Then copy/paste the version information (you can use the "Copy Information" button).
