c# - How do I make my Web API project actually see the System.Data.SqlClient NuGet package? -


there seem number of questions related this, haven't found solution problem yet. apologize if answer here , haven't found it.

i'm trying create web api project gives me middle layer between html page uploading file , sql database stores files. know it's bad approach store files in database, i'm trying make smaller test app me diagnose bigger problem in existing database can't change.

i can set controller path "api/docs/save" fine, saving file in database has become of nightmare. can't seem reference "system.data" or "system.data.sqlclient" work in project. i've tried nuget packages no luck. tried making class library using normal c# .net, adding reference class library doesn't work either.

how set web api project can use data base access methods i'm used to?

as side note: don't have access existing front end code app, can't add test page there. need create can run locally through visual studio.

i can replicate problem in vs 2017 using core 1.1 , there seem problem.

after installing nuget package save , reload project , should fine.

i'm implementing inapp billing in android app. works well, however, i'm trying decouple broadcast receiver activity manifest. suggestion in android's trivialdrive sample: // important: dynamically register broadcast messages updated purchases. // register receiver here instead of <receiver> in manifest // because call getpurchases() @ startup, therefore can ignore // broadcasts sent while app isn't running. // note: registering listener in activity bad idea, done here // because sample. regardless, receiver must registered after // iabhelper setup, before first call getpurchases(). currently there's class extends broadcastreceiver : public class iabbroadcastreceiver extends broadcastreceiver { /** * intent action receiver should filter for. */ public static final string action = "com.android.vending.billing.purchases_updated"; private final iabbroadcastlistener mlistener; public iabbroadcastreceiver(iabbroadcastlistener listener) { m
