Summary0001841: NoesisPostProcessor Fails Importing Fonts
Description

I am unable to import the following two fonts within the same project. I tried placing each font in a different directory but it fails.

Those two .ttf files refer to the same family name "Proforma", but I was able to import them to the Unity project by adding them to different folders.
The error you are getting is originated when a xaml gets imported (I guess using those fonts), could you please share how are you referencing them in the xaml?

Just to make it clear, I meant that both ttfs have the same family name and weight (400) so if you import both in the same directory, only the first registered one will be in fact used.
If you edit for example Proforma-Medium.ttf with a program like FontForge to set its Weight to 600 then both fonts can be imported in the same directory and used in xaml by selecting the corresponding FontWeight.

I've been doing some tests and I was able to reproduce that "Sharing violation" exception by having the font opened in windows and then reimporting the xaml in Unity.

To fix this I had to change how we open files in NoesisPostprocessor adding "FileShare.Read":

line 188: using (FileStream file = File.Open(font, FileMode.Open, FileAccess.Read, FileShare.Read))
line 248: using (FileStream file = File.Open(filename, FileMode.Open, FileAccess.Read, FileShare.Read))

This should work, could you try it yourself until we release a new version?

Hi Sergio -- I was referencing both versions like this:

<FontFamily x:Key="Proforma">Fonts/#Proforma</FontFamily>
<FontFamily x:Key="ProformaSemiBold">Fonts2/#Proforma</FontFamily>

The fonts conflicted despite existing in a different directory. To my knowledge, the font was not open in a third-party program other than Unity.
