Nasty MSBuild Error - MSB4126 "Debug|HPD" issue

Today I was trying to put together a simple NAnt build script for a 'play' project of mine. This build script is real simple, it only calls MSBuild right now. However, when I was running the script I kept getting the message 'error MSB4126: The specified solution configuration "Debug|HPD" is invalid.'

For the life of me I could not figure out what this was. I spent time on Google, and could not find anything useful. What made this more strange was that I could compile via the solution file.

Finally it dawned on me to check my Environment Variables on my machine. About half way down was a variable 'Platform' with a value of 'HPD'. I removed that variable, and rebooted, now all is right with the world again (ok, all is right with the build).

Hope this helps someone else out, cause I know it was pissing me of.

Till next time,

Why reboot? You just had to close your command line window and reopen a new one!

You're right ! Many thanks for this tip !

By the way, after having read your post, I found on this page (channel9.msdn.com/.../checkwhetheranenvironmentvariablehasbeenset) that MSBUILD use env var for any property missing.

I also found this page (forums.microsoft.com/.../ShowPost.aspx) where a guy explains that the PLATFORME environment variable is set by an HP utility (see the last post of the page).

Thanks again !

Thanks that tip helped. I opted to notepad my solution file then pick the appropriate platform instead of removing the variable.
