Import RAW EC public key and use it to verify signature

I am new to C# language and the Windows platform and I need some help:

• I need to import a Elliptical Curve Public Key provided to me in RAW hexstring format (or byte array) with uncompressed X and Y values. and
• Use the key imported above to verify signature of a message received in a byte array.

I have found the following docs online:

• MSFT CNG: https://docs.microsoft.com/en-us/dotnet/api/system.security.cryptography.ecdsacng?view=net-5.0

Is it the correct starting point? Are there any examples I can look at?

PS: I would like to implement this using native Windows API, and not import additional libs like Sodium, BouncyCastle, OpenSSL, etc.
