Question

Current static source analysis tools for C# (or other .NET languages) usually operate on the assembly-level. They use reflection to analyse the code.

Are there tools available that operate on a source code level only (like lint for C)?

Answer 1

IIRC, SourceMonitor works at the code level and also Microsoft StyleCop.

SourceMonitor:

The freeware program SourceMonitor
lets you see inside your software
source code to find out how much code
you have and to identify the relative
complexity of your modules.

StyleCop:

StyleCop analyzes C# source code to
enforce a set of style and consistency
rules. It can be run from inside of
Visual Studio or integrated into an
MSBuild project.
