Is System.ServiceModel.Channels.BufferManager thread safe?

I create a buffer manager through the static member BufferManager.CreateBufferManager . This newly created BufferManager used by multiple threads.

Should I use lock with TakeBuffer() and ReturnBuffer() or is it thread safe by design?

Internally, BufferManager.CreateBufferManager returns an instance of WrappingBufferManager that does not use the concurrency form, but wraps multiple SynchronizedPool<T> instances that use the internal lock on Take() in a new buffer. Therefore, judging by the simplicity of the WrappingBufferManager , we can safely assume that any lock on your part will be redundant, and that the returned class is actually thread safe.

I am having problems with the BufferManager. I created my own message encoder in WCF, and based on my observation, it did not always guarantee that a buffer manager is created for each call. Therefore, bytes are reused / returned by other threads, which leads to damage to my data.

So, to answer your question ... No, they are NOT . Since you are reusing the same instance, they are not guaranteed to be thread safe .
