There are 2 tools, (obfuscator and compressor) that are included in a single utility, which is pretty much what I need for my business. I found the documentation very helpful. However, sometimes I need to use command-line and even that is not very user-friendly. It's kind of confusing for people when they first use it. It is a very secure way to obfuscate a class library. There are a lot of benefits to using it. We are able to give access to less knowledgeable people about the software to be able to have a secure library. This way we have been able to control who gets to have access to the library. It's easy to use, it works well with all versions of Visual Studio (VS). I like that you can set different rules depending on what type of project you are working in. The price is also pretty reasonable compared to other software. If you want something that will work for multiple projects at once then this might be right up your alley! There isn't much to dislike about the product. We have been able to protect our source codes from being stolen or copied by others without getting sued.
