Issue:

Visual Studio 2005/2008 solution with mixed projects (both C++ and C#) fails with an out of memory error or with MSB4018: The "MSBuild" task failed unexpectedly

Cause: 

This problem may occur if the C# project is dependent on the C++ project(s).

This problem occurs with older IncrediBuild versions usually (v4.51 and downwards).

Fix:

Please upgrade your version of IncrediBuild to V5.0 or higher. 

If upgrading is not an option, please try the following workaround:

• On the Initiator machine, please create a registry string value named MSBuildNoDep under HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Xoreax\IncrediBuild\Builder and set its value to 1.
