sudo make install

Build and run the wrapper

From the wolfssl root directory:

cd wrapper/CSharp

Compile server:

mcs wolfSSL_CSharp/wolfSSL.cs wolfSSL_CSharp/X509.cs \
wolfSSL-TLS-Server/wolfSSL-TLS-Server.cs -OUT:server.exe

Compile client:

mcs wolfSSL_CSharp/wolfSSL.cs wolfSSL_CSharp/X509.cs \
wolfSSL-TLS-Client/wolfSSL-TLS-Client.cs -OUT:client.exe

Run the example

In one terminal instance run the server:

mono server.exe

And in another terminal instance run the client:

mono client.exe

Enabling SNI

To enable SNI, just pass the -S argument with the specified hostname to the client:

mono client.exe -S hostname

And run the server with the -S flag:

mono server.exe -S
