We used to have asp.net website projects, which does not come with project files like .csproj. We also have fckEditor folder in our project. So now every time when I build my project it unnecessarily also build fckEditor folder also which is really annoying to me ( I hate when something takes too long to build :) ).
If you are working on Asp.Net Web Application then the solution is very simple, you just have to “Exclude it” from the project. BUT we are working on WebSite project not web application project.
In fact it is quiet simple. Just hide the folder, I mean, Make the folder ( the one that you don't want to be included in compiling process) hidden and it will not be there in the build list. So simple. :)
