My solution has an absolute output path (OutDir), since the output is on a different drive from the solution, m:\exaplus\bin. However, the NCrunch runner does not handle this case and simply appends this absolute path to the workspace. Thus, the built assembly is not found (and also not properly generated). As output text in the processing queue I get the following, for example:
ERROR (Compilation): Core: (0): Unable to find built assembly. Checked locations: C:\Users\rose\AppData\Local\NCrunch\8144\9\WindowsAPI.Core\m:\exaplus\bin\Microsoft.WindowsAPICodePack.dll
