Unity，Dll上的WebServices，与.Net 4.0兼容

Question

I'm trying to use web services on unity. I used svcutil to generate a proxy class, however the proxy class was using "System.Threading.Tasks".

I noticed that System.Threading.Tasks wasn't aviable on .Net 3.5. So I went to player setting and I changed to .Net 4.x

But now I have an other issue, and I cannot find a way to fix it, I need to use System.Web.dll and System.Web.Services.dll to make my web service work, however, the dll that are include in Program Files\\Unity\\Editor\\Data\\Mono\\lib\\mono\\2.0 are all targets for .Net 3.5.

So that mean I cannot use them on .Net 4.x

I've been looking for quiet long and was unable to find any answer. I can add the code to the proxy class here if it's require, but I don't think it would be useful. Should I download those dll somewhere? Anyone ever seen thoses issues somewhere?

Answer 1

You are using the wrong dll version.

Once you change Api Compatibility Level to Net 4.x, you have to copy the System.Web.dll and System.Web.Services.dll files from <UnityInstallationDirectory>\\Editor\\Data\\MonoBleedingEdge\\lib\\mono\\4.5 to your <Project>\\Assets path.

That's it. Restart Visual Studio and Unity.
