aspnet core 2.0 dotnet run running with warning - asp.net-core

I upgraded to dotnet core SDK 2.0 from dotnet SDK 1.1, but on dotnet run projects that have been created with version 2.0.0 they run but with warnings.

Projects that were created with version 1.1 before the upgrade are running as expected. I have tried to search for guidance on how to overcome this but I have failed.
Looked at the config files, but not clear on what todo.
I have reinstalled the SDK after removing all old version, Upgraded Visual Studio Community 2017 to 15.3.5 but still stuck with the warnings.
When I browse the url http://localhost:5000 I get error

After reading .NET Core 2 does not work.... #920 resolved the problem by renaming the NuGetFallbackFolder, deleting the bin and obj folders from the project, running dotnet restore from command prompt with elevated privileges

I deleted .vs folder in beside of my solution file and the problem gone.

WindowsCryptographicException: Keyset does not exist

I want to create or obtain a certificate, create a pfx-file, load it and have IdentityServer use it. However, IdentityServer is not able to use my pfx.
How to successfully create a pfx and have IdentityServer use it?
I have an IdentityServer4 web solution running on localhost with ASP.Net Core. I am preparing the solution for production running on Azure, and is adding a certificate to the IdentityServer pipeline instead of the developer signing certificate.
Typically this means to swap code like
services.AddIdentityServer()
.AddDeveloperSigningCredential()
with
services.AddIdentityServer()
.AddSigningCredential(cert)
where "cert" is an object instance of X509Certificate2 which has loaded a PFX-file containing the certificate (with public and private keys).
The certificate I am using is self signed and is created by following the steps on Ben Cull's Blog https://benjii.me/2017/06/creating-self-signed-certificate-identity-server-azure/
The certicate and private key is exported to a PFX-file in order for both public and private key to be contained in the file.
The loading of the PFX-file succeeds. The code for loading is
cert = new X509Certificate2(Path.Combine(Environment.ContentRootPath, "MyPfxFile.pfx"), "password-used-when-exporting-pfx");
The Pfx-file is located within the web project and is found and read into the X509Certificate object.
When inspecting the X509Certificate2 in Visual Studio the property HasPrivateKey return true, but the PrivateKey property resolves to an exception in the watcher.
'cert.PrivateKey' threw an exception of type 'Internal.Cryptography.CryptoThrowHelper.WindowsCryptographicException'
All other properties look sound and good in the watcher.
Also, when I execute the GetRSAPrivateKey in the Immediate Window method on the certificate object instance, it returns an exception.
cert.GetRSAPrivateKey()
'cert.GetRSAPrivateKey()' threw an exception of type 'Internal.Cryptography.CryptoThrowHelper.WindowsCryptographicException'

I have tried loading the pfx-file with different settings for X509KeyStorageFlags, but the behaviour and exceptions are the same.
I have also tried to install the PFX into the Windows machine's certificate manager, and I am successfully loading it from there, but the same exceptions are thrown.
At last, when requesting an access token from IdentityServer, the same exception is thrown. I have pasted the exception trace below.

The problem was resolved by adding IIS_IUSR group.
From this link Add group IIS_IUSR:
The problem was that the Permissions for the Private Key of the Certificate in the Windows Certificate Store did not have the IIS_IUSRS group set to allow read access.
Right click certificate -> All Tasks -> Manage Private Keys -> Add group "IIS_IUSRS"
I followed that blog post too and also had that issue.
The problem was when you run this to create PKCS12 file:
openssl pkcs12 -export -out example.pfx -inkey example.key -in example.crt -certfile example.crt
Try to remove -certfile example.crt and it should work.
Also according to .NET Core X509Certificate2 usage (under Windows/IIS, Docker, Linux) you can test if certificate was loaded from file correctly by accessing cert.PrivateKey.
E.g.
X509Certificate2 cert = new X509Certificate2(Path.Combine(Directory.GetCurrentDirectory(), "cert.pfx"), "password");
Console.WriteLine("cert private key: " + cert.PrivateKey);
On IIS 10 I had to change my app pool identity to LocalSystem
Oh hey, that's my blog post! Glad to see that it's... well hopefully helping despite problems people run into. Speaking of which I have now run into this exception myself!
My problem was that I created the certificate and tried to load it from disk using the new X509Certificate2(path, password) syntax, but for some reason I had to import the cert into the registry on my development machine to stop the exception from occuring. I'm not actually sure why.
Make sure to import the certificate to the My/Personal store of the CurrentUser registry.
There are so many different answers on this thread, I hope one of them works for you, reader :)
In my case, which by the way wasn't an API but a class library, I just had to make sure I was running visual studio in admin mode and that this user I was opening the visual studio with, was the same one who had the certificate installed in the store/mmc. Reach out if any question.

GET of smidge'd scripts/css fails with 500 error - InternalCreateDirectory throws

Smidge 3.0.0
I am following the instructions in https://github.com/Shazwazza/Smidge to the tee. But havent been able to get smidge to work for me. I get a 500 error on GET of the bundle js/css files. After some digging in Chrome debugger, I was able to find that the error seems to be related to Smidge being unable to create the cache folders. Here's the stack - I repro'd it by just trying to navigate to the bundle JS file like this:
GET http://localhost:8241/sb/app-scripts.js.v3
results in:
UnauthorizedAccessException: Access to the path 'C:\Users\USERNAME\source\repos\PROJECTNAME\App_Data\Smidge\Cache\MACHINENAME\3' is denied.

IIS is running on a different account and it does not have permissions to write to your profile folders. Change the application so that it does not have to access profile folders or folders that require specific permissions.

Value cannot be null. Parameter name: address at IdentityModel.Client.TokenClient

We have create IdentityServer4 application with ASP.NET Core(http://docs.identityserver.io/en/release/quickstarts/0_overview.html) and deployed it on our qa server(i.e. https://identityserver.mydomain.com). We have also created the AWS Server application in .NET Core(https://aws.amazon.com/blogs/developer/preview-of-the-aws-toolkit-for-visual-studio-2017/) and this serverless application internally call the connect/token endpoint of identity server application.(i.e. https://identityserver.mydomain.com/connect/token).
public async Task<TokenResponse> CreateAccessToken(string baseUrl, string client, string clientSecret, string scope)
{
//discover endpoints from metadata
var disco = await DiscoveryClient.GetAsync(baseUrl);
//request token
var tokenClient = new TokenClient(disco.TokenEndpoint, client, clientSecret);
var tokenResponse = await tokenClient.RequestClientCredentialsAsync(scope: scope);
return tokenResponse;
}
Everything is working on our localhost but after deploying the Serverless application on AWS we are getting following error:
Unknown error responding to request: ArgumentNullException:

So it turns out that I renamed my web project and it's namespaces but forgot to do the rename in the _ViewImports.cshtml file.
I feel really stupid.
This error happens because your views don't have a namespace reference to the classes in the Models folder.In the older versions of MVC you would solve this problem by adding <add namespace="MyProjectNamespace.Models" /> to the Web.config file inside the Views folder.
In .NET Core this issue can be solved by adding the following line to your _ViewImports.cshtml:
#using MyProjectNamespace.Models

GenerateEmailConfirmationTokenAsync(user) generates error Encryption Failed

A call to GenerateEmailConfirmationTokenAsync(user) method returns with the error message Encryption Failed
This is a .Net Core Application with a resource server and an authentication Server.The User Accounts Management is being done on the resource server. When execution gets to
var code = await _userManager.GenerateEmailConfirmationTokenAsync(user);
I get the error message Encryption Failed
