exception when viewing pages of security\authentication-with-identity sample

[LeiYangGH]

I'm using .net 5.0.102 and when viewing pages got following exceptions.
Did I miss something? but the readme doesn't say any special configurations.

Oh bummer. Let me check it tonight when I have access to my computer. Thanks for the report.

[dodyg]

Didn't get a chance last night. Will try today.

[LeiYangGH]

thanks!

[dodyg]

It's fixed. Just download the latest version.

You can see the fixes in these two commits

Thanks for filling an bug report.

[LeiYangGH]

Sorry for late response but i still fail to run this sample( different error this time). Before creating a new issue, i'd like to post the issue here and see if there's any feed back.

Steps:

1. clone latest repo, branch net5.0
2. go to projects\security\authentication-with-identity, run build.bat
3. run authentication-with-identity.exe

Exceptions:

[dodyg]

I will review this today.

[LeiYangGH]

maybe it was due to lack of some database in my environment?
but if the readme contains steps to setup(such as where to specify connection strings, and whether some initialize sql is needed) then it will be great.

[dodyg]

There shouldn't be. The DB is in memory.

Cannot resolve scoped service 'WebApplication.Data.ApplicationDbContext'

This is weird

practical-aspnetcore/projects/security/authentication-with-identity/src/Program.cs

Line 34 in b86266d

services.AddDbContext<ApplicationDbContext>(options=>

The code is right there.

Can you try changing the UseSqlite

=> options.UseSqlite(@"Data Source=C:\identity.db");

[LeiYangGH]

Changed to this:

			services.AddDbContext<ApplicationDbContext>(options=>
				options.UseSqlite("Data Source=C:\\identity.db"));

But error is the same.

@lohithgn What do you think is the problem here? We need a third pair of eyes

[lohithgn]

@dodyg will take a look at it and will update

[lohithgn]

@dodyg I have no issue running the sample. I tried the following two ways of running the app:

1. Navigate to projects/security/authentication-with-identity/src. then dotnet build. then dotnet run. Was able to register a user, login and logout
2. Navigate to projects/security/. Execute build.bat. Navigate to projects/security/authentication-with-identity/src/bin/debug/net5.0. Execute exe authentication-with-identity.exe. I was able to register a user, login and logout.

The logs are not providing any other information. so that's tricky to iron this out.

[lohithgn]

having said that - i tried above steps from command line.

I just opened the project in Visual Studio and i put a breakpoint in line 81 in program.cs. I see the exception.

interesting ...

[lohithgn]

@dodyg @LeiYangGH can you try the following code for Configure()

public void Configure(IApplicationBuilder app, IWebHostEnvironment env, ApplicationDbContext dbContext)
        {
            if (env.IsDevelopment())
            {
                app.UseDeveloperExceptionPage();
            }

            app.UseRouting();

			app.UseAuthentication();
            app.UseAuthorization();
            app.UseEndpoints(endpoints =>
            {
                endpoints.MapDefaultControllerRoute();
            });

            using (var client = dbContext)
            {
                client.Database.EnsureCreated();
            }
        }

[Tratcher]

It's recommended to set up the database in Main and to directly create the DI scope required.
https://docs.microsoft.com/en-us/aspnet/core/tutorials/razor-pages/sql?view=aspnetcore-5.0&tabs=visual-studio#add-the-seed-initializer

[lohithgn]

@Tratcher that is true.

@dodyg may be you can update the sample. Dont do the DB initialize check in Configure() instead do it in Main.

[LeiYangGH]

@lohithgn I CAN run the sample if update code like you wrote above. Thanks!

Configure(IApplicationBuilder app, IWebHostEnvironment env, ApplicationDbContext context)
...

[lohithgn]

@LeiYangGH we are working on a better solution than what i proposed. i am in the middle of creating a PR. I suggest you wait for the PR to be merged.

[lohithgn]

@LeiYangGH here is the PR which is the correct way of doing the DB creation - #291

[dodyg]

Excellent - thanks everyone. I never use EF Core so I have no idea about this subtleties in behavior.

[lohithgn]

Startup is a magic. You need to know when the Configure() and ConfigureServices() are called in the lifecycle :). This was not EF thing - rather - what is the right place to ensure database is created. Happy to help anytime :)

[dodyg]

You need to know when the Configure() and ConfigureServices() are called in the lifecycle :).

This can be a new sample
