+1. Install vs-android from [Source4Android Project](https://github.com/GuestSneezeOSDev/source4android) or [vs-android GitHub repo](https://github.com/gavinpugh/vs-android)
+2. Edit your `server.vcxproj` and `client.vcxproj` and add this between line 5 or 12 or somewhere else. [1](https://github.com/GuestSneezeOSDev/source4android)
+```xml
+<PropertyGroup Condition="'$(Configuration)|$(Platform)'=='Release|Android'">
+  <OutputPath>$(SolutionDir)bin\$(Configuration)\android\</OutputPath>
+</PropertyGroup>
+```
