I\'m having trouble while building my WPF solution. Everytime I try to build it, I get this error message:

Unknown build error, \'The specified path,

Answer 1

No worry....This error comes because of long path name,Suppose your project folder name is "myproject".

You Just Change location of project folder...Put your Project "myproject" to D:\myproject or or F:\myproject drive.Then You Publish again..Its work...

Happy Coding...
