I was referring to "https://github.com/ewoutkramer/fhir-net-api".
Can any one help me with sample implementation, on evaluating FHIRPath expressions in c#.

Thanks in Advance.

Note that the R4 support is a little older in that from the source perspective, waiting for the official NuGet package to be released. And as such this is still using the 0.96 version of the fhir package references...
If you're wanting to see how to write the code to use the expression evaluation, it will now look a little different, but not too much.

But if your content is DSTU2 or STU3, the expression evaluation is pretty simple...

Note that the way I detect which version of FHIR the document is, I just attempt to parse with each of the versioned parsers which changed with the 1.x series of assemblies so is broken to just update at the moment too.
The more recent versions might have better luck using the PermissiveParsing settings, but I haven't had time to update and try with that yet.
