error CS0246 未能找到类型或命名空间名AssemblyVersionAttribute

Translation: error CS0246: Could not find type or namespace name "AssemblyVersionAttribute"

This error message indicates that the compiler was unable to find a reference to the "AssemblyVersionAttribute" class. This class is typically used in .NET applications to specify the version number of an assembly.

To resolve this issue, you may need to add a reference to the assembly that contains the definition for the "AssemblyVersionAttribute" class. Alternatively, you could try qualifying the attribute with the namespace in which it is defined, like this: [System.Reflection.AssemblyVersionAttribute("1.0.0.0")]
