NetMQ Version: latest at 6 Aug (probably 4.0.0.0 as *.csproj says).
Built from sources for .NET FW 4.8
Operating System: Win7 x64 SP1
.NET Version: Framework 4.8
Sample
Sample is taken from "HelloWorld" of the author:
var client = new RequestSocket("tcp://localhost:5556");
client.SendFrame("123");
After SendFrame is executed, clumsy dialog with "Assert" appears (which says me literally nothing what and where is wrong). In V2Encoder.cs I replaced line 38 (with assertion) to this:
if (m_inProgress.UnsafeData == null) throw new Exception("m_inProgress.UnsafeData is NULL!");
...and only then I could catch in VS debugger where problem happens (client or server) and what's going on + stack: m_inProgress.UnsafeData really was null, but... WHY??

It's elementary program, which must work w/o any efforts! In reality I cannot send even "123". I repeat: code is taken from author sample, so it should be verified 100%.
