LogicalThreadContext stops UnitTest in Visual Studio

Hello,

I use log4net in my application for logging. In one day unit tests stopped in visual studio. There was error:

An exception occurred while invoking executor 'executor://mstestadapter/v2': Unable to find assembly 'log4net, Version=2.0.8.0, Culture=neutral, PublicKeyToken=669e0ddf0bb1aa2a'.

I spend much time to find problem.

I have in my ctor this:

public Logger()

{

log = log4net.LogManager.GetLogger(typeof(Logger));

log4net.LogicalThreadContext.Properties["LogRunId"] = 0; //get max+1 log from database

{color:#880000}}

When I comment second line unit test works fine. When I change LogicalThreadContext to ThreadContext it works fine. If there is LogicalThreadContext error is shown. Why?
