Dotfuscator ships with a simple command line utility that ‘tampers’ with an assembly. It is called TamperTester.exe and is installed in the same folder as Dotfuscator itself.
Usage: tampertester <file_name> [destination folder]
By running your Dotfuscator assemblies through this utility, you can test that the tamper notification messages are being generated and sent as expected. You can also test any application code you have written to execute in response to tamper detection.
