I created a new class libary project (Visual Basic Code) and I used the dataset wizard to create a dataset so I could get data from the database, everything seems to work fine but when I try to compile my project I got this error: "Task DevartEntityDeploy couldn't be loaded from the assembly. C:\WINDOWS\Microsoft.NET\Framework\v3.5\Devart.Data.Entity.Build.Tasks.dll. The file or assembly couldn't be loaded 'Microsoft.Data.Entity.Build.Tasks, Version=3.5.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a'. The system couldn't find the file. Confirm that the declaration is correct, and that the assembly and all its dependencies are available."
I look up for the error and I got this file C:\Program Files\MSBuild\v3.5\Custom.After.Microsoft.Common.targets giving some trouble

please I need help, thanks in advantage
PD: sorry my english is not good...
