# Enforce Code Style in Builds
# For builds, outside of Visual Studio, you can enable code style analysis for .NET projects by
# setting the EnforceCodeStyleInBuild property to true in the VS .csproj file.
# Example:
# <PropertyGroup>
# <EnforceCodeStyleInBuild>true</EnforceCodeStyleInBuild>
# </PropertyGroup>
# See https://docs.microsoft.com/en-us/dotnet/core/project-sdk/msbuild-props#enforcecodestyleinbuild
# Note: This feature is currently experimental and may change between the .NET 5 and .NET 6 releases.
