Could not determine whether 'assembly' is a multifile assembly. The assembly manifest may be corrupt. Assuming a non-multifile assembly.
The project system was unable to read an assembly referenced by your project, such that the project system is unable to determine whether you are referencing a multifile assembly. Therefore, the assembly may not be copied properly to the output directory.
To correct this error
- Reinstall Visual Studio (if the assembly came with Visual Studio or the .NET Framework).
- or -
- Reinstall the appropriate third-party control.
This error will not prevent the project from building. However, a run-time error is possible.
