ServiceStack NuGet update 4.0.22 to 4.0.31 caused errors on deployment

Question

I\'m hoping not to be to vague here, but I\'ve just done a NuGet update for ServiceStack, updating from version 4.0.22 to 4.0.31, the project compiles fine but once deployed to

Answer 1

I had the same problem, and I believe I've traced it back to not having KB2468871 installed on some client machines. This causes weird errors such as the one you are seeing. My particular one was this:

Method 'GetAsync' in type 'ServiceStack.JsonServiceClient' from assembly 'ServiceStack.Client, Version=4.0.30.0, Culture=neutral, PublicKeyToken=null' does not have an implementation.

I tried adding the System.Net reference and that didn't clear it up either.

For now, I'm sticking with 4.0.24 (the pre-PCL version) until I can come up with a better solution, since I'm not in control of the client environment. Note that if you are using ClickOnce, you can add this particular update as a prerequisite to the bootstrap installer, but it won't have an effect on already-installed machines, thus the problem here.
