dnu restore using old version of Newtonsoft.Json.Dll

[ArryMatt]

When doing a dnu restore I get the following error:

System.MissingMethodException: Method not found: 'Newtonsoft.Json.Linq.JValue Newtonsoft.Json.Linq.JValue.CreateNull()'.

Reading up on this I've found that older versions of Newtonsoft.Json do not have the method CreateNull().

I had v6.0.0.0 in my GAC, which I have removed and added v7.0.0.0. This did not help.

I found a couple of old versions in Native Image directories in my GAC, which I have removed, still no help.

Searching my machine finds a lot of copies of this. So, how can I find out where it's getting the bad one from and either remove it or tell it to use a different one?

You can't tell it to use a different one. You could try to use something like process explorer to see where it's loading that dll from.

Many thanks, process explorer found the dodgy version and once deleted it now works.
