[XVS 3.9.221] Opening the iOS Build properties changes MtouchDebug on unmodified template projects


The symptoms of this bug are similar to bug 24150, but this bug is about the `MtouchDebug` property.

Regression status: Regression between 3.8.150 and 3.9.221.



## Steps to reproduce

1. Create a new iOS project, for example a "Visual C# -> iOS -> Classic API -> iPhone -> Blank App".

2. Wait for the template to finish loading.

3. Right click the project name in the Solution Explorer and select "Properties".

4. Note that the "iOS Build -> Debugging Options -> Enable Debugging" checkbox is empty and the tab shows an asterisk indicating something has changed.

5. Close the Properties pane.

6. Click the start debugging button to attempt to build and debug the app on device.



## Results

XamarinVS removes the "Enable Debugging" setting every time it opens the iOS project properties.


I suspect this corresponds to the `MtouchDebug` property in the `.csproj` file:
> <MtouchDebug>False</MtouchDebug>


This causes VS to display the following error message in an alert dialog after step 6:

> Microsoft Visual Studio
>
> Debug is not enabled in the current configuration. Please Start Without
> Debugging or change it in Properties -> iOS Build.



## Expected Results

Opening the project properties should not change the "Enable Debugging" setting.

We were indeed overwriting some configurations while loading the iOS Build property panel, which was confusing and annoying.

Fixed

v3.9

Comment 4 Mohit Kheterpal 2015-01-02 05:14:14 UTC
I have checked this issue using XVS 3.9.230 and this issue is working fine now i.e. I am able to save setting of enable/disable debugging in a solution as shown in screencast : http://screencast.com/t/oygaOC2mtI

Xamarin.VisualStudio_3.9.230_34e781562d8fb4ba7eff85874271bce6c999619a

Hence closing this issue.
