# Directory.Build.props and Directory.Build.targets files These files allow you to easily configure property defaults for all projects in a folder. For details see [Customize Your Build](https://docs.microsoft.com/en-us/visualstudio/msbuild/customize-your-build) on Microsoft docs. Due to an MSBuild bug, when using this file for AssemblyInfo, the attributes are generated for the first target framework only. See this issue: https://github.com/dotnet/msbuild/issues/3802. For differences about these two files and for help about which one to use see [[Readwise/Articles/Difference Between Directory.Build.props and .Targets Is Not Clear]].
