Twitterizer 2 and C# - Namespace could not be found

Question

I have a silly problem with Twitterizer2 and probably me :) . I add the reference twitterizer 2.3.1 from my downloads directory along with the newtonsoft one by right clicking on references and browsing to find them.

I then add

using Twitterizer;

lo and behold all my squiggly red underlines go away

on all this sort of code:

OAuthTokens tokens = new OAuthTokens();

when I go to run it(with debug), I get an error:

Error 2 The type or namespace name 'Twitterizer' could not be found (are you missing a using directive or an assembly reference?)

Now using Twitterizer;

becomes in error(red and squiggly). It is like it has been dereferenced. I add it back and all is well until I run it - arggh

TIA

Answer 1

Are you using VS2010? If so, try to go project properties -> Application Tab and make sure that you are not using a Framework version that has "client profile" in it.

Answer 2

If you are using VS2010 vb.net you need to go to project properties ->Publish Tab-> Prerequisites

Uncheck ms .net framework 4 client profile, and check ms .net framework 4
