1 Introduction Since months now, there are huge problems with the Xamarin-Integration software and Visual Studio, like:

Visual Studio has to be closed and restart after a debug-session

Objects are “unknown” in debugger and can’t be inspected although they exist (code run’s)

App can’t be debugged on iPhone-device (app is deployed but then cannot be started for debugging on device)

Strange behavior with breakpoints (don’t stop or stop but at “false” breakpoint)

Extremely slow especially on Android (first breakpoint is reached in VS in normal time, but then a spinning wheel is showed for minutes until VS can be served)

Problems with Windows-Emulator (don’t start - “Port is in use from another application”

Error-Messages on MAC to the Xamarin-Certificate

and so on… Strange wise the behavior is not the same every day. One day, an app can be debugged in iOS-Emulator only one time until the error message to “ConvertPdbToMdbTask” (cannot access as another process has the file in use):

occurs, sometime the app can be debugged e.g. 4 times until the error is shown and VS has to be restarted. The same is true for the other problems. At 20.05.2015, Ian Ceicys (“Xamarin-Ian”) has asked me, if I would try the newest “pre-Alpha”-releases (as he know, that I have massive problems) and give him some feedback. As I think, it can’t become worse as it is for me, I have invested the time and have done the test now (note: I don’t have installed every new release since a few weeks now). As I think, my findings may also be interesting for other users, I have wrote this document, sent it to Ian and also post a Link in the Forum. Notes:

I think, the problems depends on various things (including OS, VS-Version, etc.)

…so my findings are for my environment and can be false for your environment.



2 Environment

2.1 New installed files

Ian have sent me download-links to:

monotouch-8.10.1.59.pkg ( 1 ) and

Xamarin.VisualStudio_3.11.576.msi ( 2 ) I have downloaded both on my windows-machine:

I then have copied the .pkg on a network-share and from the network-share to the local-drive of the MAC (as I was not able to install it from the network-drive)

Then I have unpaired the BuildHost on MAC, closed XS, XCode and BuildHost on the MAC and run the .pkg in the MAC

After that, I have rebooted the MAC

Then I have closed VS, run the .msi on my Windows machine and rebooted also the windows machine

After all, I have paired the Mac to the Windows machine again and started the test

2.2 After installing the updates (= base for my test) VS2013 - Update 2 with:

Integration: 3.11.576.0

Xamarin.Android: 5.1.2.0

Xamarin.iOS: 8.10.1.0 Mac with:

Xamarin Studio: 5.7.1 (Build 17):

XCode; 6.1 (6A1052d

Xamarin.iOS: 8.10.1.59

Xamarin Build Host 3.11.0.577:

Xamarin.Android: 4.20.0.28

RunTime Mono 3.12.0

2.3 First start VS after installation

After the first start, I was asked, if I want to enable automatic error-reporting to Xamarin ( 1 ), what I have done, as I have seen, that there is an new checkbox in the VS-option-settings to Xamarin ( 2 ) where I can disable the “automatic feedback”, if I want.

Note: I don’t know since which version this is included as I have skipped some versions…

3 Summary - (my) Conclusion By my short test, it seems (not sure right now!) as:

The problem with error message “ConvertPdbToMdbTask is in use by another process” (workaround was to restart VS) has gone or at least has become much better

The extremely slow debugging in Android (VS shows spinning wheel for minutes after the first break-point is reached) has gone or at least has become much better

I further have found a “workaround” for the problem “port is already in use” with the WP-Emulator while I have investigated the new versions

(My) other problems are the same:

Debug to iOS-Device (iPhone and iPad) is not possible (while iOS Emulator still works)

Some objects are still “unknow” in debugger, while they exists

Xamarin-Update service is not reachable sometimes If the following issues still exists, I don’t know (as I don’t was able to test it):

Strange behavior with break-points (especially in Async functions)

Problems with the Xamarin certificate on the MAC

So - although the “old” problems still are there, the new version is an improvement for me.

You will find all the details in the chapter “Findings”.



4 Findings

4.1 Problem „object xx unknown“ Since a few versions, I am not able to see (inspect) some objects in debugger as VS says, that they are “unknow”. As I have started developing with Xamarin (August 2014), I don’t had this problems. Later the problem have started with iOS and Android and since a few versions, I also have it in WP.

4.1.1 iOS (Emulator)

In my App.cs, I have set a breakpoint where I overtake the properties from the Application object ( 1 )

The code ( 1 ) works, but I can’t inspect the XF-Variables ( 3 ) and ( 4 ) whereby I can see and inspect my own variables ( 4 )

4.1.2 WP (Device)

Same as in iOS-Emulator

4.1.3 WP (Emulator) First try:

Since weeks I am not able to use the WP-Emulator. Every time I start it, it shows the error-message that the communication-port is already in use of another application ( 1 )

I then have searched the internet, checked all suggestions (what have cost a few hours) to find

out a workaround (but not a solution)

See also chapter “Workaround for problem “Port is already in use” (WP)

WP-Emulator (after doing the workaround):




4.1.4 Android (Device) First and second try:

Details:

After rebuild the Android-project, I was able to debug to the Android-device:


4.1.5 Conclusion Problem „object xx unknown“ Same as before Unfortunately, nothing has changed with the update.



4.2 Workaround for problem “Port is already in use” (WP) Since weeks I am not able to use the WP-Emulator. Every time I start it, it shows the error-

message that the communication-port is already in use of another application ( 1 )

I then have searched the internet, checked all suggestions (what have cost a few hours) to find

out a workaround (but not a solution)

1



As I wrote, I have tried various “solutions”:

delete some files

check ( 2 ), stop ( 3 ) and restart ( 4 ) the virtual machine to the WP-Emulator

where, b.t.w. the name has changed from vmm to vmms (in the (old) messages I found, the

mentioned name was vmm)

Shut down process for process in Task Manager to find out which process is capturing the WP Emulator-port (I was not able to find out which port is used b.t.w)

All without luck….

The only workaround I found (that works for me) is:

Every time, I want to debug to the WP emulator, I first have to deploy the app to the emulator ( 1 )

After that, I am able to debug one time to the emulator

So.. I always have first to deploy and then to debug to the emulator

Update: later in the test, I have tried to directly debug to the WP-Emulator and it have (strange wise) also worked without to deploy before… (so maybe this has to be done only one time…)

So.. it seems as this is an „old” problem to the WP Emulator, but I don’t had this problems as I have started with XF. In the meantime I have installed the Xamarin Android Player (don’t use it, but have it installed), which installs various other software-peace’s including another VM (I think it’s from Oracle). maybe the problems came from this, maybe not…

4.3 Problem „debugging extremely slow” with android As I wrote in the Introduction, the debugging in Android was incredible slow:

If I have set a breakpoint (in app.cs), the break-point was reached in “normal” time, then a “spinning wheel” was showed for minutes until VS was servable

Like many other issues, strange wise the behavior was not the same every day

4.3.1 Conclusion „debugging extremely slow” with android Checked with the new version:

Compile, remove old version and store new version to the device (Samsung Tablet SM 900) takes about (long) 55 Seconds

This is a long (but acceptable) time and has (felt) not changed

The break-point is reached in “normal” time VS is now servable immediately

So… this seems to be fixed…

But… as I wrote, the behavior is not every day the same… the time will show, if really is fixed…

4.4 Problem „VS has to be restarted after debugging” (ConvertPdbToMdbTask-Errormessage) As I wrote in the Introduction, I had since a long time the problem, that an error message to “ConvertPdbToMdbTask” (access not possible as it is in use of another process).

Sometimes I had this problem immediately (after first debug session after boot the windows machine and start VS), sometimes the problem came after a time working

I then had to close and restart VS to be able to debug further one time

4.4.1 Conclusion (ConvertPdbToMdbTask error message) I have tried to provocate the problem by doing a “stress-test”:

Debug to iOS-Simulator a few times, then to Android-Device then to WP-Device, then to iOS-Simulator, and so on

I was not able to provocate it

So… this seems to be fixed… or at least much better…

But… as I wrote, the behavior is not every day the same… the time will show, if really is fixed…



4.5 Problem „debugging to iPhone 5 device don’t work” As I wrote in the Introduction, I was not able to debug to/on my iPhone 5 device (while the Emulator has worked).

4.5.1 Re-Test

If I debug to my iPhone 5:

The message “Launching Application for debugging…” ( 1 ) is showed with a brown background (like it normally should be)

After a while, the background-color change ( 2 ) and the error message ( 3 ) is showed ch Error-message in plain text (in German): Fehler 105 error MT1007: Failed to launch the application 'com.yourcompany.MatrixGuide' on the device 'iPhone von Fredy Wenger': Look for earlier warnings returned: 0x454. You can still launch the application manually by tapping on it. Xamarin.iOS Extension 0 0 The error-message suggest in my understanding, that I should be able to debug anyway, if I start the app on the device manually… I was not able to do it..

4.5.2 Try to find out the reason Note: If you don’t know this function already, it may be useful for you anyway… Some time ago, I have noted (randomly) that under Help ( 1 ) - Xamarin ( 2 ) ther is an option “Zip Xamarin Logs” ( 3 ) where I (you) can export some log-files to / for Xamarin in a .zip-file ( 4 )

I have done this and tried to check it out… (see next page)

I have store the .zip-file in c:\temp\ ( 6 ), opened the .zip-file and sort it to datetime ( 7 )

Then, I have double-clicked the latest ”WCF Trace File” ( 8 ), set a filter to “Error or higher” ( 9 ) and double-clicked the Item ( 10 )

Then I have tried to find the correct entry to the issue ( 11 ) and was able to find it ( 12 ) Plain-Text: Build server returned an Error. warning MT1003: Could not kill the application 'com.yourcompany.MatrixGuide'. You may have to kill the application manually. warning MT1108: Could not find developer tools for this 8.3 (12F70) device. Please ensure you are using a compatible Xcode version and then connect this device to Xcode to install the development support files. error MT1007: Failed to launch the application 'com.yourcompany.MatrixGuide' on the device 'iPhone von Fredy Wenger': Look for earlier warnings returned: 0x454. You can still launch the application manually by tapping on it. Please ensure your device is connected... Connected to: iPhone von Fredy Wenger

According to the (bold) error message I tried to check, if a new XCode-Update is available but don’t find any option “Search for updates” or something similar in Code in the MAC. I then have found how to update XCode in StackOverflow:

Done and found no update… Then have noted, that there is an error-message to Android in the same second as the error message is to the iOS-deploy:

Details:

Plain text: MonoTouchDebuggerSession Mono.Debugging.Soft.ConnectionException: Could not connect to the debugger. ---> System.IO.IOException: DWP Handshake failed. Server stack trace: bei Mono.Debugger.Soft.Connection.Connect() bei Mono.Debugger.Soft.VirtualMachine.connect() bei Mono.Debugger.Soft.VirtualMachineManager.Connect(Connection transport, StreamReader standardOutput, StreamReader standardError) bei Mono.Debugger.Soft.VirtualMachineManager.ConnectInternal(Socket dbg_sock, Socket con_sock, IPEndPoint dbg_ep, IPEndPoint con_ep)

bei System.Runtime.Remoting.Messaging.StackBuilderSink._PrivateProcessMessage(IntPtr md, Object[] args, Object server, Object[]& outArgs) bei System.Runtime.Remoting.Messaging.StackBuilderSink.AsyncProcessMessage(IMessage msg, IMessageSink replySink) Exception rethrown at [0]: bei System.Runtime.Remoting.Proxies.RealProxy.EndInvokeHelper(Message reqMsg, Boolean bProxyCase) bei System.Runtime.Remoting.Proxies.RemotingProxy.Invoke(Object NotUsed, MessageData& msgData) bei Mono.Debugger.Soft.VirtualMachineManager.ConnectCallback.EndInvoke(IAsyncResult result) bei Mono.Debugger.Soft.VirtualMachineManager.EndConnect(IAsyncResult asyncResult) bei Mono.Debugging.Soft.SoftDebuggerSession.<>c__DisplayClass9.<StartConnecting>b__8(IAsyncResult ar) --- Ende der internen Ausnahmestapelüberwachung --- So.. I think the error-messages are related I have sent this problem already to Xamarin and also mentioned it on a thread posting in

February 2015 here: http://forums.xamarin.com/discussion/comment/106850/#Comment_106850

Comment Xamarin (Brendan) “Looks interesting” I will fill a bug

He then has filled a bug here: https://bugzilla.xamarin.com/show_bug.cgi?id=27776

Actual state in Bugzilla is still “New”

4.5.3 Conclusion Problem „debugging to iPhone 5 device don’t work” Bug still exists

I have investigated it already in February 2015, a bug is filled, nothing heard about…

The same is true for my iPad

So… I’m not able to debug in my iOS-devices (iPhone and iPad) So... please check it out and solve it!

4.6 Problem „strange behavior with break-points” As I wrote in the Introduction, I have noted some strange behaviors with break-points (especially in async functions).

Unfortunately, I don’t had the time to check this out with the new version yet.

4.7 Further (general) Problems

4.7.1 Problem „Error-Messages on MAC to the Xamarin-Certificate“ Since some time ago I have the problem, that Xamarin Studio on the Mac shows error-messages to a Xamarin-Certificate (unfortunately I don’t have a Screenshot from).

If the error message is showed, the messagebox has to be confirmed (felt) 30-40 times, before XS on the MAC becomes servable again.

Don’t had the error message since the update but that does not means, that the issue is gone.

4.8 Problem „Xamarin is not reachable for check updates “ Often (right now), the Xamarin Update-server is not reachable ( 1 ), although the Internet connection works ( 2 )
