I'm trying to define a P/Invoke signature for the following method (defined in propsys.h)

PSSTDAPI PSRegisterPropertySchema(
    __in PCWSTR pszPath);

I've seen on the WinNT.h that PCWSTR is an alias to LPCWSTR as

typedef __nullterminated CONST WCHAR *LPCWSTR, *PCWSTR;

And the PSSTDAPI is an alias for HRESULT

So how should be the P/Invoke signature for the PSRegisterPropertySchema method?

Dynamic Type to do away with Reflection

The dynamic type in C# 4.0 is a welcome addition to the language. One thing I’ve been doing a lot with it is to remove explicit Reflection code that’s often necessary when you ‘dynamically’ need to walk and object hierarchy. In the past I’ve had a number of ReflectionUtils that used string based expressions… >>> More
