Q:

dotNetRDF VS Jena.NEt VS others with Dotnet ?

what is the most common tool used for Reading & Writing RDF and Querying with Sparql with different end points .
so far i've found 

Jena (jena.net) :  it's developed for Java but some people managed to   convert it to Assemblies 
DotnetRDF

i wonder if there are others and which one is best to use what the the pros and cons  ? 

A:

Both of the above are good. Other ones include:
Sesame - Java covering RDF, SPARQL, OWL. Actively developed    
Redland, Raptor Rasqal - C & Ruby, covers everything, actively    developed 
ARC2 - PHP, RDF, SPARQL, no longer activel developed
You've also got a lot of supporting frameworks for things like ORDFM that build off the above namely:
Jenabean
Empire
AliBaba
RDFReactor
RDFBean

A:

the best answer i've found in Answers.semantiweb

Give a try to dotNetRDF.
I have been used it in one of my projects and I am satisfied with it.
It is SPARQL-capable, supports both local and remote queries and, the
  most important, it is actively maintained

i've started using dotnetRDF the creator also have left a good documentation on the website 
http://www.dotnetrdf.org/
and a good tutorials as well
