Attempts to compile a library file in IBM Rational Functional Tester (RFT) .NET 2010 result in a compile error on the first row and column.
The consequence is that you cannot compile any script.
You upgraded RFT to 188.8.131.52. In your previous environment the project compiled error free. Re-installation and downgrade to RFT 184.108.40.206 does not improve the situation.
The cause is unknown.
Resolving the problem
Roll back to your last check-in that you compiled successfully.
