Known issues

Razor compilation is slow if you have a space in your username

aspnet/Razor#2406 - when building an ASP.NET Core app as a user with a space in username, build times may be a few minutes more than it takes when building as a different user.

Solutions:

1. Add a PackageReference to your project file (.csproj) to update the Razor compiler.

<PackageReference Include="Microsoft.AspNetCore.Razor.Design" Version="2.1.2" />

2. Change your username to something without spaces.

EntityFrameworkCore commands in the Visual Studio Package Manager Console issue a warning

When using EntityFrameworkCore commands in the Package Manager Console, you may see a warning with this text.

The EF Core tools version '2.1.1-rtm-30846' is older than that of the runtime '2.1.2-rtm-30921.' Update the tools for the latest features and bug fixes.

Available solutions:

1. Do nothing. This warning can be ignored for now. We are working on a fix for a future 2.1 update.
2. Update the version of the Microsoft.AspNetCore.App package.

<PackageReference Include="Microsoft.AspNetCore.App" Version="2.1.3" />

⚠️ This may have unintended consequences on your deployment environment. If the deployment environment does not have the the 2.1.3 runtime, apps will fail to start with an error. In Azure or apps hosted behind IIS, this may appear as HTTP 502.5 error.

It was not possible to find any compatible framework version
The specified framework 'Microsoft.AspNetCore.App', version '2.1.3' was not found.

Version mismatches can cause apps to fail with System.IO.FileLoadException

Some ASP.NET Core 2.1 applications will be affected by a bug in the .NET Core host (see dotnet/core-setup#4512) which can cause apps to fail with System.IO.FileLoadException. The issue may also be present in your app, even if the app does not fail with System.IO.FileLoadException.

This issue and workarounds are described in greater detail in #3503

Known Issues

• Warning when building new ASP.NET Core project that targets .NET Framework
  Building a new ASP.NET Core project that targets net461 produces the following warning:

  There was a mismatch between the processor architecture of the project being built "x86" and the processor architecture of the reference "c:\Program Files\dotnet\sdk\NuGetFallbackFolder\microsoft.aspnetcore.mvc.razor.viewcompilation\2.1.0-rtm-30796\build\netstandard2.0\Microsoft.AspNetCore.Mvc.Razor.ViewCompilation-x64.exe", "AMD64". This mismatch may cause runtime failures. Please consider changing the targeted processor architecture of your project through the Configuration Manager so as to align the processor architectures between your project and references, or take a dependency on references with a processor architecture that matches the targeted processor architecture of your project
  

  Workaround: Remove the reference to the Microsoft.AspNetCore.Mvc.Razor.ViewCompilation package.

• Windows authentication is not enabled after creating project with the Windows authentication option selected
  When creating a template with Windows authentication, the settings to enable Windows authentication in launchSettings.json are not applied.
  Workaround: Modify launchSettings.json as follows:

  "windowsAuthentication": true,
  "anonymousAuthentication": false,
  

• NullReferenceException when using a custom IAuthorizationPolicyProvider and AllowCombiningAuthorizeFilters is set to true
  Using a custom IAuthorizationPolicyProvider and setting AllowCombiningAuthorizeFilters to true causes a NullReferenceException.
  Workaround: Disable AllowCombiningAuthorizeFilters or use a single AuthorizeFilter

• XmlSerializerOutputFormatter throws InvalidCastException for async action methods
  Invoking an Async action method may result in an InvalidCastException when using the XmlSerializerOutputFormatter.
  Workaround: Wrap the return type in ActionResult<T>. Ex. replace the return type Task<IEnumerable<string>> with Task<ActionResult<IEnumerable<String>>>.
