❔ Startup File to Program file

services.AddTransient<ISqlDataAccess, SqlDataAccess>();
            services.AddTransient<IContactData>, ContactData>();

services.AddTransient<ISqlDataAccess, SqlDataAccess>();
            services.AddTransient<IContactData>, ContactData>();

I watched a tutorial video where the code above was called in the Startup.vsmean while I only have a Program.cs . Is there a way I can call this in Program.cs

short answer: yes it's code you can call whatever code you want in code that you write it's called writing code long answer: that's presumably a snippet of setup code for the Microsoft.Extensions.DependencyInjection library where services is an IServiceCollection if you're building something like ASP.NET or something based on Microsoft.Extensions.Hosting or maybe a MAUI app the app framework already has an IoC/DI container, you just need to configure it as an example

anita•2y ago

builder.Services.AddTransient etc

JakenVeina•2y ago

using var host = Host.CreateDefaultBuilder()
    .ConfigureServices(services => services.Whatever())
    .Build();

host.Run();

using var host = Host.CreateDefaultBuilder()
    .ConfigureServices(services => services.Whatever())
    .Build();

host.Run();

this would essentially be your Main() method if you're not using something like this, you can still use the MS.E.DI library, you just have to set it up yourself

using var rootServiceProvider = new ServiceCollection()
    .AddWhatever()
    .BuildServiceProvider();

rootServiceProvider.GetRequiredService<Whatever>()
    .DoSomething();

using var rootServiceProvider = new ServiceCollection()
    .AddWhatever()
    .BuildServiceProvider();

rootServiceProvider.GetRequiredService<Whatever>()
    .DoSomething();

This didn't work

anita•2y ago

can you show how your program.cs looks? @dlaw_code

dlaw_codeOP•2y ago

Ok. In a jiffy

dlaw_codeOP•2y ago

anita•2y ago

oh, what doesnt work? you are already doing the same thing with the AddSingleton<>. Just put in this code after the addsingleton call:

builder.Services.AddTransient<ISqlDataAccess, SqlDataAccess>();
builder.Services.AddTransient<IContactData, ContactData>();

builder.Services.AddTransient<ISqlDataAccess, SqlDataAccess>();
builder.Services.AddTransient<IContactData, ContactData>();

dlaw_codeOP•2y ago

I put it but it's bringing error

anita•2y ago

Ok, but this has nothing do to with the difference between startup.cs and program.cs. You are just missing some import statements and/or nuget package references. what tutorial are you following?

dlaw_codeOP•2y ago

Tim Corey What nuget package reference do you think am missing

anita•2y ago

that's a youtube channel, what tutorial are you following? not shure tbh, i cant find anything that has and IContactData Interface. is this an interface that you have created?

dlaw_codeOP•2y ago

Yeah I thought maybe it's cos he's using an older version of .NET Cos am working with .Net 6

anita•2y ago

if you have defined the interface and class, then this shouldn't make a difference you just need do add a using statement

dlaw_codeOP•2y ago

I thought so too Now i have no idea of what using statement i can use

anita•2y ago

in what namespace is the interface defined?

Pobiega•2y ago

Those seem to be self-created types, not library provided

anita•2y ago

yes, thats why i am trying to find out in what namespace the types are

Pobiega•2y ago

Ctrl+T, type "IContactData" select first hit. check namespace.

dlaw_codeOP•2y ago

Pobiega•2y ago

so in your program.cs using DataAccessLibrary; you need to have a reference to that project, if they are different projects (which I assume they are)

dlaw_codeOP•2y ago

This is what it brought

Pobiega•2y ago

The entire purpose of that was to find IContactData and check the namespace something you already did 8 minutes ago :p

dlaw_codeOP•2y ago

Lol. Am sorry. Didn't get that ???

Pobiega•2y ago

???

dlaw_codeOP•2y ago

What should i do next?

Pobiega•2y ago

Did you add the using statement to program.cs?

dlaw_codeOP•2y ago

U mean the

using DataAccessLibrary?

using DataAccessLibrary?

Pobiega•2y ago

yes.

dlaw_codeOP•2y ago

Yeah i did but it didn't work

Pobiega•2y ago

"didn't work" doesnt help me at all what exactly do you mean by that Im sure VS is giving you some errors

dlaw_codeOP•2y ago

I mean it brought error

Pobiega•2y ago

So show the errors. I cant see your screen

dlaw_codeOP•2y ago

Pobiega•2y ago

hm, this seems odd your Program class isnt in a namespace thats.... very unusual also, I think you are missing a project reference

dlaw_codeOP•2y ago

Pobiega•2y ago

so add the missing ; then we add the project reference

dlaw_codeOP•2y ago

I added it. Stil the same thing How do i add the project reference

Pobiega•2y ago

find your project in the solution explorer expand "dependencies" and right click it then do "add project reference"

dlaw_codeOP•2y ago

Ok. In a jiffy

dlaw_codeOP•2y ago

This is what brought. Is it the one?

Pobiega•2y ago

yep check that box. then click ok Your program is split in multiple projects, and they are not by default aware of eachother

dlaw_codeOP•2y ago

Ok I have done that. What's next?

Pobiega•2y ago

your problem should now be solved.

dlaw_codeOP•2y ago

still showing

Pobiega•2y ago

open your .csproj for the blazor project show content

dlaw_codeOP•2y ago

How do i locate that

Pobiega•2y ago

its your project file

dlaw_codeOP•2y ago

u mean this?

Pobiega•2y ago

yes, doubleclick that should open it as text

dlaw_codeOP•2y ago

U mean this?

Pobiega•2y ago

your project reference wasnt saved did you press cancel :p

dlaw_codeOP•2y ago

Nah

Pobiega•2y ago

If you say so but the fact is that it wasnt saved. ¯\_(ツ)_/¯

dlaw_codeOP•2y ago

How do i save it?

Pobiega•2y ago

by clicking the "OK" button after checking the box

dlaw_codeOP•2y ago

I have done that already

Pobiega•2y ago

If you say so. but from what I can see, the project reference was not saved

dlaw_codeOP•2y ago

Am confused bro with the project

Pobiega•2y ago

I can see that. I think you've been moving a bit too fast in your ambition and should repeat the basics a bit more

dlaw_codeOP•2y ago

Okies Bro. Thanks. I would just take my time to go through the project again and see where the error is coming from. Thanks for the help anyways

Pobiega•2y ago

best of luck.

dlaw_codeOP•2y ago

Bro. I figured it out Already

Pobiega•2y ago

Great. What was it?

dlaw_codeOP•2y ago

I moved the Sqldata and the Contactdata class into the Data folder But i encountered another error someplace again🙁

Was this issue resolved? If so, run /close - otherwise I will mark this as stale and this post will be archived until there is new activity.
