Description James 2015-01-22 17:11:15 UTC
Opening up the project settings for a Xamarin.Forms application in iOS. When opening the iOS project build properties, if you set linker behavior to a new setting, i.e. change from "Link All Assemblies" to "Link SDK assemblies only" and then save with command+s, the dirty dot goes away, but when you close, re-open the project settings the linker behavior is still set to "Link All Assemblies"

It appears the same behavior happens with "Use SGen generational garbage collector"

Verified on there different machines, screen cast here:

This bug is similar to bug 25582.

Upon further investigation, this bug does not appear to be a duplicate of bug 25057 because bug 25057 was reported against 3.8.150, and this bug does not occur on 3.8.150.


Regression status: regression between 3.8.150 and 3.9.228 (see version information below)



## Steps to reproduce

1. Open an iOS project (Classic or Unified).

2. Open the project properties.

3. Change the "iOS Build -> General [tab] -> Linker behavior" from "Link all assemblies" to "Link SDK assemblies only".

4. Save and close the project properties.

5. Re-open the project properties.

6. Toggle either the "iOS Build -> Enable Debugging" setting or the "Optimize PNG images files for iOS" setting twice. This step is just to force VS to treat the properties as if they have changed.

7. Again save, close, and re-open the project properties.



Note: I was _not_ able to hit any similar problem with the "iOS Build -> Advanced [tab] -> Use SGen generational garbage collector" setting using these steps to reproduce.


## Results

After step 3, the `.csproj` file properly records the linker setting:

> <MtouchLink>SdkOnly</MtouchLink>


At step 5, the project properties _incorrectly_ show the linker setting as "Link all assemblies".



After step 6, the `.csproj` file reflects the new _incorrect_ setting from step 5:
> <MtouchLink>Full</MtouchLink>


At step 7, the project properties _incorrectly_ show the linker setting as "Link SDK assemblies only".
