Description Brendan Zagaeski (Xamarin Team, assistant) 2015-05-22 20:33:21 UTC
"Enable developer instrumentation" has no effect in XVS because it corresponds to unused DevInstrumentationEnabled property

This is a companion bug for Bug 30372 to provide a "practical use scenario" that can be tested in relation to that bug. Bug 30372 should be fixed first, just keeping this bug in mind. Then this bug can be verified as an extra assurance that the fix for Bug 30372 has the desired behavior in a "practical use scenario."

(Note: if I were to attach a zipped up test case on this bug, it would be identical to the new project template, and the steps to reproduce would be identical after step 2. So I won't worry about attaching a test case.)

## Steps to reproduce

1. Create a new "Visual C# -> Android -> Blank App (Android)" project.

2. Open "Project Properties -> Android Options".

3. Un-check "Enable developer instrumentation (debugging and profiling)". (As described in Bug 30372, this sets the $(DevInstrumentationEnabled) property to False, but it should probably instead set $(DebugSymbols) to False and $(EmbedAssembliesIntoApk) to True.)

4. (Optional) Also un-check "Use Fast Deployment" to more closely match the Xamarin Studio behavior at step 3.

5. (Optional) On XVS 3.9 and earlier (where Bug 30057 is not a problem), you can also optionally disable Use Shared Runtime, and even enable the Linker if you like.

6. Save the project properties.

7. Set a breakpoint in the `OnCreate()` override, for example on `SetContentView(Resource.Layout.Main)`.

8. Start debugging the app on device or emulator (for example via "Debug -> Start Debugging").

## Results

The debugger _does_ break on the breakpoint in the `OnCreate()` override.

## Expected results

The debugger should NOT break on the breakpoint. The user has explicitly disabled the "developer instrumentation," so the user would expect breakpoints _not_ to work. Indeed if you try the same steps in Xamarin Studio on Windows, the breakpoint is _not_ hit after step 8.
