Some RSACryptoServiceProvider methods not available in .net 4.5.2

Question

I'm facing an issue trying to use some RSACryptoServiceProvider methods, more specific the VerifyData().

I'm working on a project which compiles in both net452 and netstandard2.0.

When I add the nugget and try to use it's methods, I see the following message. enter image description here

Does anyone knows why is this happening? Because regarding to the official microsoft documentation this library is compatible with net452.

Thank you so much!

I did a research in order to find different rsa tools

.NET Standard 2.0 is aligned with .NET Framework 4.7.2, not .NET Framework 4.5.2. The particular method you're looking at was added in .NET Framework 4.6.

FWIW, .NET Framework 4.5.2 (and 4.6, and 4.6.1) went out of support in 2022 so you should hopefully be able to move your netfx minimum to 4.6.2 with little resistance.
