Compiler Error C3163
'construct': attributes inconsistent with previous declaration
The attribute(s) that are applied to a definition conflict with the attribute(s) that are applied to a declaration.
One way to resolve C3163 is to eliminate attributes on the forward declaration. Any attributes on a forward declaration should be less than the attributes on the definition or, at most, equal to them.
A possible cause of the C3163 error involves the Microsoft source code annotation language (SAL). The SAL macros do not expand unless you compile your project by using the /analyze flag. A program that compiles cleanly without /analyze might throw C3163 if you attempt to recompile it with the /analyze option. For more information about SAL, see SAL Annotations.
Example
The following sample generates C3163.
// C3163.cpp
// compile with: /clr /c
using namespace System;
[CLSCompliant(true)] void f();
[CLSCompliant(false)] void f() {} // C3163
// try the following line instead
// [CLSCompliant(true)] void f() {}
