Working with a precompiled VB.net website

I am working with a precompiled ASP.net website. I have most of the *.aspx.vb files, but I am missing some of the library files, and only have the DLLs. Can I still selectively compile aspx.vb files? When I just hit build, It errors with 'This application is alread开发者_开发知识库y precompiled'

If you have DLLs, then most likely those are external assemblies which are not part of the project, to which the source files belong. So if you have a project file, try compiling it and see if it reports missing source (.vb) files. Most likely compiler will give you hints regarding particular problems.

If you don't have a project file, the situation becomes more complicated. You might need to use some decompiler tool (9rays.net decompiler is a good one) to restore the source files from compiled DLL (note - main project DLL, not those library DLLs) and analyze what's missing and what was included.
