Loadrunner 12.53 and .net 4.5.1


I've win app developed in .Net 4.5.1. I used LoadRunner 12.53 to record and compile it in LoadRunner editor but it displays the list of errors related to .Net 4.5.1 (it works fine with win app in .net 4.0). But it I opened Script.sln by Visual Studio, it compiled without error and run script again in LoadRunner editor, it works well.

Please help me solve the issue when compile script in LoadRunner editor with .Net 4.5.1

Thanks so much,
