Description Prashant [MSFT] 2017-04-11 07:32:39 UTC
VS 2017 hangs in project loading a Xamarin.Android project with no AndroidManifest.xml file reference

# Steps to reproduce
1. Create a new Xamarin.Android project, and close Visual Studio
2. Remove the `<AndroidManifest>Properties\AndroidManifest.xml</AndroidManifest>` line from `PropertyGroup` in the csproj file
3. Open the Solution in VS 2017

# Expected behavior
The solution should load in the VS 2017 without hanging

# Actual behavior
VS 2017 hangs trying to load the solution. This worked in the Cycle 9 release

Comment 4 John Miller [MSFT] 2017-05-01 20:18:53 UTC
## Bookkeeping note

I will prepare a non-engineering team preliminary quick review for this report. I was able to reproduce with the given steps. 

## Suspected to be a regression or a problem with a new feature?
Unclear. It would be good to test a previous build. 

## Already took up time for many users? 
Unclear. The OP links to the forum posts for the user reporting this. 

## Makes development (a) difficult, impossible, or potentially hazardous, (b) moderately inconvenient, or (c) mildly inconvenient for users?
(b) This seems to be related to a customization for controlling manifests per build configuration and is not the default setup for the .csproj
