"Type or namespace ‘Aspose’ could not be found" Error Occurs in VS2010 and .NET 4.0 Client Profile

Hello, Team.
I have been tried for using Aspose.Slides, but “Type or namespace ‘Aspose’ could not be found” error occurs while building a project.
Words, Cells and Note work fine, but only Slides makes a problem.
I’m using VS2010 in Win7, and .NET 4.0 Client Profile(a link for my test project is attached)
I got 21.10 dll only from “Download .NET DLL to Read Edit Presentations | Aspose.Slides
If I have been something wrong, please let me know.
Thank you for your help.

@54ms,
Welcome to our community! Thank you for the issue description.

Unfortunately, I was unable to reproduce the error you described. I logged the issue with ID SLIDESNET-42900 in our tracking system. Our development team will investigate this case. We will inform you of any progress.

Thank you for your help.
I found out that the Slides works fine in the target framework “.NET 4.0”.
If the target framework is “.NET 4.0 Client Profile”, the error occurs even I use dlls in “net4.0_ClientProfile” directory

@54ms,
Thank you for the additional information.

@54ms,
Please try to add System.Web assembly in your project and let us know if it helps.
