[Bug 46654] dotnet35sp1 fails to install with winetricks

https://bugs.winehq.org/show_bug.cgi?id=46654

--- Comment #2 from Brendan McGrath  ---
Thanks Hans - I can confirm that with this patch applied, I can successfully
install dotnet35sp1 with winetricks.

I also noticed that another issue now appears to be fixed. In Wine 4.1, after
the install of dotnet35sp1, the machine.config under Framework64 was always
missing the:
- system.runtime.serialization;
- system.serviceModel; and
- system.serviceModel.activation

section groups.

But with the latest from GitHub (and this patch applied) that no longer seems
to be the case. So that is fixed too!
