Hi all

I get this error after running some tests in FB:

**(CoreCompile target) -\>

**&nbsp;&nbsp;&nbsp; 3 Warning(s)  
&nbsp;&nbsp;&nbsp; 1 Error(s)**

Which results in a build error, the strange thing is that the results DO&nbsp;get published.

Any ideas where to start?

Kev

Hi Kevin   
  
 A strange one indeed (the fact that mstest reports an error and still actually publishes the tests).   
  
 The way this works is we generate an xml file in the format required by mstest and then execute mstest. To figure out what is happening we really need to see the xml file. Please install this build :   
  
 [https://www.finalbuilder.com/downloads/finalbuilder/630/FB630\_1745.exe](https://www.finalbuilder.com/downloads/finalbuilder/630/FB630_1745.exe)   
  
 What this build does differently is it does not delete the xml file when mstest reports a non zero return code, and the error exception will include the name of the xml file. Please send the file to support at finalbuilder dot com so we can see what it is failing on.
