I wrote a C# class Library (.dll) wish as you know does not use a Main() but I am using to be used with a Web Application and PreApplicationStart in assemblyinfo.cs gets called. How can I do a software integrity test or do a internal check sum or the dll to make sure it has not change using HMAC SHA or SHA sum? I've done this with c program but not sure how with C# library.
