Exception while running simple WPF application published with PublishTrimmed=true

[MartinStrbak]

Steps to reproduce:

1. Create new WPF application (via CLI - dotnet new wpf).
2. Add Textblock element to MainWindow.xaml, so it contains
   <Grid> <TextBlock>Hello, world</TextBlock> </Grid>
3. Publish application with PublishTrimmed set to true (dotnet publish -c Release -r win-x64 -o C:\example /p:PublishTrimmed=true)

Application does not start and exception is logged in Event Log:

Application: example.exe
CoreCLR Version: 4.700.19.30373

Seems to be duplicate of dotnet/linker#595.
