.NET Instrumentation

The Antithesis platform can automatically instrument compiled .NET assemblies by means of bytecode weaving. No changes to your source code or build system are required.

Place directories, files, or symlinks to the code you want instrumented or cataloged in the directory /opt/antithesis/catalog/ within your container image. Antithesis will follow all symlinks while resolving the path to the cataloging directory.

However, it will follow only one symlink deep into each item placed within /opt/antithesis/catalog/. That is, you should not symlink to a symlink.

Example cataloging directory:

> ln -s /usr/share/my_app /opt/antithesis/catalog 

> ls -lAh /opt/antithesis/catalog
lrwxrwxrwx  1 me users 4 Apr  8 17:32 /opt/antithesis/catalog -> /usr/share/my_app

> ls -lAh /opt/antithesis/catalog/
-rwxr-xr-x  1 me users  20K Apr  8 17:33 dotnet_file.dll
lrwxrwxrwx  1 me users 27 Apr  8 17:52 more_files -> /opt/my_project/java_files 
-rwxr-xr-x  1 me users  10K Apr  8 17:33 python_script.py

> ls -lA /opt/antithesis/catalog/more_files/
-rw-r--r--  1 me users  16K Apr  8 17:51 main.jar
lrwxrwxrwx  1 me users  16K Apr  8 17:51 my_other.jar -> /some/other/place.jar

Based on the example above, the following files would be instrumented:

• dotnet_file.dll
• python_script.py
• main.jar

Ignored files:

• my_other.jar - this will be ignored as we already encountered one symlink when traversing down from opt/antithesis/catalog/more_files.

Antithesis will recursively instrument all *.dll or *.exe files except System.*.dll and Microsoft.*.dll, which are excluded by default.

Symbolization

Antithesis will automatically gather the symbol information from your code. You do not need to separately provide us with symbol files.
