If the DLL file contains any intermediate language (IL), you can view the IL code using the IL Disassembler tool, which is installed alongside Visual Studio. Retrieve the LoaderExceptions property for more information. But being able to step through my hypothetically new algorithm on a whim is otherwise known as reverse engineering intellectual property.

VS itself only decompiles declarations. Tested. They are temporary and will be deleted by Visual Studio. Our engineering team is working to integrate ILSpy technology into valuable debugging scenarios. the lost file using decompiling it. I for one can always tell when code has been developed without R# as the gutter lights up like a Christmas tree with all the analysis and resulting warnings. Shows metadata tokens of classes and members. The best possible solution so far is use dotPeek, put all *.dll files into one folder and use Explore Folder option. Includes file header information in the output. We have mitigated the failure by catching these issues and gracefully failing the decompilation attempt. Note that this feature is more about DEBUGGING the de-compiled code inside VS, which is why it is a good feature, not just about de-compiling them. Shows actual bytes, in hexadecimal format, as instruction comments. That's probably the easiest way. My values for given dll are: App_Web_xxxxxx.aspx.cdcab7d2, Version=0.0.0.0, Any help will be appreciated and thanks in advance :).

However it is missing some of the features that other more scary decompilers have like: Get started | dotPeek Documentation When you're debugging and no source code is available, Visual Studio shows the Source Not Found document, or if you dont have symbols for the assembly, the No Symbols Loaded document. Why did DOS-based Windows require HIMEM.SYS to boot?
