Question

My team and I get this error often but random and we’re not sure why it does this. To get around it we either build the solution a couple of times of have to restart Visual Studio (10). Here’s the error i have when i try to build :

Error 5 The "GenerateApplicationManifest" task failed unexpectedly.

Thanks for your help!

I had run into a similar issue and found that it was because one of my assembly’s path was too long. I don’t really understand why in some cases it may work for you, and in others it doesn’t though, so it may be something else, but never hurts to check it out.

I believe the maximum length is 260 characters.
