error occurrance while validating HRESULT = '80004005'

i have created a windows service in visual studio c#.net ,and i am trying to create a set up and deployment for the service, when i am buiding the windows service project ,it is successful

i have added the Project Output Group as Primary Output with windows service project. i have also added the custom action to the set up project,

when i try to build the set up project it displays"An error occurred while validating. HRESULT = '80004005'" i also noted there is nothing in the detected depende开发者_如何学编程ncies folder.

I had the error code 8000000A, so it might be different, and I'm not sure if this is any help for your problem. But re-adding references did not work for me. However, what worked for me was removing the .suo file (next to the .sln) and (re)building again.

(It might have been caused by accidentally opening a Visual Studio 2010 class library in a Visual Studio 2008 comapct project. I am not even going to try reproducing this!)

Removing the .suo will make you 'loose' your open files (and maybe some other settings?), but IMHO that's just a small sacrifice(?).

I just hope this will save someone some time...

I've just had exactly the same issue with a WinForms project. I had several projects in my solution, they would all build without an issue except for the set up project.

I overcame this by removing all the references to the other projects in the solution in the main project (the one that was being set as primary output) and then re-adding them again by going to add reference >> project. Once I had re-added the references to the other projects in the solution, the project dependencies re-appeared and all built fine.

Hope that helps
