Limitations

The library reads the compiled code, so it does not see the uses that leave no trace in it:

• Constants: the compiler copies the value of a const field and of an enum value into the code that uses it, so using Limits.Max gives no dependency on Limits. A default parameter value is a constant too.
• nameof: nameof(Order) is a string in the compiled code.
• Reflection and configuration: a type created with Activator.CreateInstance, found by name, or registered from a configuration file is not a dependency of the code that does it.
• Types named in strings: an attribute argument that names a type in a string is not a dependency. A typeof argument is.

Other limits:

• The assertions of Assert.Architecture apply to types. To check members, query the model and use Assert.All, as shown in Type rules.
• The types marked with CompilerGeneratedAttribute are not part of the architecture, including the types a source generator marks with it.
• The source locations require a portable PDB. Windows PDBs, produced by old projects with DebugType set to full or pdbonly on .NET Framework, give no location.
• The base types and interfaces defined outside the architecture are read from the referenced assemblies, searched in the folders of the loaded assemblies, the folders of ReferenceSearchDirectories, and the assemblies of the running .NET. When an assembly is not found, the hierarchy stops at the type it defines.
