How to specify assembly:ThemeInfo() with the new project system?

[lennartb-]

I just migrated a pre-2017 csproj to the new 2017 format. I noticed that default styles specified in themes\generic.xaml were not automatically applied anymore, and after comparing to the old project found out that [assembly: ThemeInfo(ResourceDictionaryLocation.None, ResourceDictionaryLocation.SourceAssembly)] was omitted from the now auto-generated AssemblyInfo file. I know that you can add certain attributes, such as InternalsVisibleTo with an AssemblyAttribute in the csproj file, but apparently only strings are supported. Is it possible to somehow insert that without disabling GenerateAssemblyInfo (and continue using the normal AssemblyInfo)?

Assembly-level attributes can go in any file you want - you don't need to put them in a file called "AssemblyInfo.cs".

Now (VS2022) you can do this:

<AssemblyAttribute Include="System.Windows.ThemeInfoAttribute">
	<_Parameter1>System.Windows.ResourceDictionaryLocation.None</_Parameter1>
	<_Parameter1_IsLiteral>true</_Parameter1_IsLiteral>
	<_Parameter2>System.Windows.ResourceDictionaryLocation.SourceAssembly</_Parameter2>
	<_Parameter2_IsLiteral>true</_Parameter2_IsLiteral>
</AssemblyAttribute>

Dont forget to add GenerateAssemblyInfo :

<PropertyGroup>
  <GenerateAssemblyInfo>true</GenerateAssemblyInfo>
</PropertyGroup>
