ConnectionMultiplexer.Connect breaks while connecting to redis server

问题

I successfully installed the Redis server on my Windows 7 machine. Did a quick hands on, everything works as expected. (installed using the MSI installer from https://github.com/MSOpenTech/redis )

I am using the StackExchange redis client C# for connecting to Redis server.
RedisClient

P.S. : I did not build the application on my machine as I am having VS 2010 and that was throwing some error. So i installed the nuget package and now my Test App in C# has the assembly StackExchange.Redis

My console app is simple with just one line of code

    ConnectionMultiplexer redis = ConnectionMultiplexer.Connect("localhost:6379,allowAdmin=true");

It gives me an error :

System.AggregateException was unhandled
  HResult=-2146233088
  Message=One or more errors occurred.

回答1:

For anyone else who stumbles on this the cause is a version mismatch with the Microsoft.Bcl package. Run the command Update-Package Microsoft.Bcl to resolve.
