winapi - Cannot install Microsoft.NETCore.UniversalWindowsPlatform -


seemed related this: nuget error install package microsoft.netcore.universalwindowsplatform not, because checkbox checked default in vs2017. running creators update way , up-to-date.

i have started new c# background iot project , got this:

enter image description here

when manually installing package in package console got this:

...

successfully installed 'microsoft.net.native.compiler 1.6.0' projectnamehere

install failed. rolling back...

package 'microsoft.netcore.jit.1.0.3' not exist in project

...

package 'microsoft.netcore.jit.1.0.3' not exist in folder

...

install-package : not install package 'microsoft.netcore.jit 1.0.3'. trying install package project targets '.netcore,version=v5.0', package not contain assembly references or content files compatible f ramework. more information, contact package author.

seems related https://connect.microsoft.com/visualstudio/feedback/details/1617801/newly-created-universal-app-projects-dont-work

but have no idea how fix it. have seen website suggesting remove project.json file, did did not resolve it.

i have closed vs2017 , modified installtion verify creators update sdk checked , installed.

i have lowered target version in project props, did not either.

enter image description here

edit manual install jit package did not work either:

could not install package 'microsoft.netcore.jit 1.1.1'. trying install package project targets '.netcore,version=v5.0', package not contain assembly references or content files compatible framework. more information, contact package author.

edit2 funny thing solution explorer tells me there project.json while there none in windows explorer:

enter image description here

i verified sdk installation hitting modify button of vs2017 installation , tried create new project afterwards got exact same issue again.

update: microsoft updated templates in github (https://github.com/ms-iot/samples/commit/2e2aa34ab514b8c0725a53263898a412e0a1be1c) didn't push updated templates package visual studio yet. changed answer accordingly.

temporary fix:

  • replace in .csproj file

<itemgroup>   <!-- reference entire .net framework , windows sdk automatically included -->   <none include="project.json" /> </itemgroup>

with 

<propertygroup>   <restoreprojectstyle>packagereference</restoreprojectstyle> </propertygroup>
  • add microsoft.netcore.universalwindowsplatform package

optional extra: add windows iot extension sdk via references dialog

inversion of control - Autofac named registration constructor injection -

does autofac support specifying registration name in components' constructors? example: ninject's namedattribute . you need use autofac.extras.attributed package on top achieve this so let's have 1 interface , 2 classes: public interface ihello { string sayhello(); } public class englishhello : ihello { public string sayhello() { return "hello"; } } public class frenchhello : ihello { public string sayhello() { return "bonjour"; } } then have consumer class, in want select instance injected: public class helloconsumer { private readonly ihello helloservice; public helloconsumer([withkey("en")] ihello helloservice) { if (helloservice == null) { throw new argumentnullexception("helloservice"); } this.helloservice = helloservice; } public string sayhello() { return this.helloservice.sayhello()...

verilog - Systemverilog dynamic casting issues -

i've code snippet following in testbench function void write_to_port( my_data_type_base data ); my_data_type_extended data_ext; if(!$cast(data_ext, data)); `uvm_error(get_type_name(), "failed cast"); `uvm_info(get_name(), $psprintf("data_ext :\n%s", data_ext.sprint()), uvm_medium) // write data_ext out port.... endfunction when run it, i'm getting uvm_error "failed cast." i'm not quire sure why $cast not returning 1. can see, i'm printing out extended class data item after casting uvm_info. can see it's being cast properly. if don't use $cast if condition, don't runtime error. isn't coding practice use if dynamic cast check if $cast returning 1 ? what might reason behind cast not returning 1 in above case? i think semicolon on line 'if' not belong? i think consumes if statement, , uvm_error executes regardless of how if evaluates: if(!$cast(data_ext, data)); <- no semico...
