Activities of "trendline"

And, I am using asp.net core Zero, it seems in the StartUp.cs no extensions like app.SetDataProtectionProvider(), like below:

        app.UseAbp();

        app.MapSignalR();

Yes, some error in logs, this maybe related with SignalR

I already checked the post, I am not using Azure, I am using my own server.

On more question:

where to implement a custom Cryptography logic in Protect/Unportect methods? which file to modify?

Is there a v4.7.1 download available? The download url you provided I can't access, GitHub.com display 404 page, is there permission issues with my account?

One more question, Where to get the latest metronic theme?

I got this exception log from windows application logs, but now the issue resolved, but I don't know how it is be fixed. May be it caused by the connection string to database is not correct, but before I update the connection string when the website first running the dataset also be initialed created, so I don't think it is caused by database connection string, really is an outlandish exception, and it cost me a lot of time investigate it.

Many thanks for your support.

I already fixed by install .Net core 1.1.0 runtime on my machine.

It already existed the configurations in global.json. It seems no entrance to install the Microsoft.NetCore.App 1.1.0

Could you write some walkthrough code?

If more than one DbContext under the *.EntityFramework.project, and other DbContexts also inherit from AbpZeroDbContext, that will cause the DbSets in AbpZeroDbContext be instanced more than once?

<cite>ismcagdas: </cite> Hi,

Actually changing solution name after project creatin is not suggested but I understand there might be such a need after some time of development.

We didn't share our project renaming code because of licensing issues, see <a class="postlink" href="https://github.com/aspnetzero/aspnet-zero/issues/200">https://github.com/aspnetzero/aspnet-zero/issues/200</a>.

In your case I think you need to change project names in WebContentDirectoryFinder.cs. But if you even solve this problem, there might be some other issues.

Where I can find WebContentDirectoryFinder.cs file?
