How to connect certificate to C # client for ODATA service?

Question

We have an ODATA service that is protected using certificates. We use AddWebReference to get proxies in our C # code.

Is there a way to bind a certificate that is in our certificate store to this generated proxy class?

We can add a certificate using HTTPClient, but we would like to avoid using HTTPClientto talk to our ODATA service and prefer to use the AddWebReference method.

I think this is probably already 3 years for you, but I hope it will help someone.

ClientCertificate :

// Get the store where your certificate is in.
var store = new X509Store(StoreName.My, StoreLocation.LocalMachine);

store.Open(OpenFlags.ReadOnly);

// Select your certificate from the store (any way you like).
X509Certificate2Collection certColl = store.Certificates.Find(X509FindType.FindByThumbprint, yourThumbprint, false);

// Set the certificate property on the container.
container.ClientCertificate = certColl[0];

store.Close();
