+ms.date: 11/6/2024
+---
+
+# Dev cert export no longer creates folder
+
+When you export the ASP.NET Core development certificate (which is used to enable HTTPS in local development), it no longer creates the directory into which the certificate is being exported if that directory doesn't exist.
+
+This change first appears in .NET 8.0.10 and .NET 9 RC 1.
+
+## Version introduced
+
+.NET 9 RC 1
+
+## Previous behavior
+
+Previously, if the destination directory didn't exist when the `dotnet dev-certs` command was run, it was created (with permissions inherited from the containing directory). For example, *C:\\NonExistent\\* would have been created given the following command:
+
+```dotnetcli
+dotnet dev-certs https -ep C:\NonExistent\cert.pfx
+```
+
+## New behavior
+
+Starting in .NET 9, if target directory doesn't exist, the export fails with a message like:
+
+> There was an error exporting the HTTPS developer certificate to a file.
+
+## Type of breaking change
+
+This change is a [behavioral change](../../categories.md#behavioral-change).
+
+## Reason for change
+
+The development certificate is exported with its private key, so unauthorized access can be problematic. It might, nevertheless, be necessary to make it readable to multiple accounts, for example, if the consuming process won't be run as the current user. Rather than attempting to determine (and securely establish) permissions for the target directory, `dotnet dev-certs` requires that it already exist.
+
+## Recommended action
+
+Create the target directory (with appropriate permissions) before invoking `dotnet dev-certs`.

+description: Learn about the breaking change in ASP.NET Core 9 where having multiple constructors in a middleware type can cause an exception at run time.
+ms.date: 11/6/2024
+---
+
+# Middleware types with multiple constructors
+
+Previously, when a middleware type with multiple satisfiable constructors was instantiated from the dependency injection container, the one with the most parameters was used. Now that only happens if the dependency injection container implements <xref:Microsoft.Extensions.DependencyInjection.IServiceProviderIsService>. If it doesn't, an exception is thrown at run time.
+
+## Version introduced
+
+.NET 9 RC 1
+
+## Previous behavior
+
+Previously, the first of the following two constructors was preferred (when both were satisfied) because it has more parameters.
+
+```csharp
+public class CookiePolicyMiddleware
+{
+    public CookiePolicyMiddleware(RequestDelegate next, IOptions<CookiePolicyOptions> options, ILoggerFactory factory)
+    {
+        // ...
+    }
+
+    public CookiePolicyMiddleware(RequestDelegate next, IOptions<CookiePolicyOptions> options)
+    {
+        // ...
+    }
+}
+```
+
+## New behavior
+
+Starting in .NET 9, neither constructor is preferred, and construction fails with an error like:
+
+> System.InvalidOperationException: 'Multiple constructors accepting all given argument types have been found in type 'Microsoft.AspNetCore.CookiePolicy.CookiePolicyMiddleware'. There should only be one applicable constructor.'
+
+## Type of breaking change
+
+This change is a [behavioral change](../../categories.md#behavioral-change).
+
+## Reason for change
+
+The activation mechanism was changed to help support keyed dependency injection.
+
+## Recommended action
+
+If this happens and you can't upgrade to a dependency injection container that implements <xref:Microsoft.Extensions.DependencyInjection.IServiceProviderIsService>, you can add the <xref:Microsoft.Extensions.DependencyInjection.ActivatorUtilitiesConstructorAttribute> to the preferred constructor of the affected middleware type.
+
+## Affected APIs
+
+This change is known to cause errors when instantiating <xref:Microsoft.AspNetCore.CookiePolicy.CookiePolicyMiddleware?displayProperty=fullName> with [Autofac.Extensions.DependencyInjection](https://www.nuget.org/packages/Autofac.Extensions.DependencyInjection) 7.x.

+---
+# 'dotnet watch' incompatible with Hot Reload for old frameworks
+
+.NET 9 introduces a change that requires [`dotnet watch`](../../../tools/dotnet-watch.md) to launched with Hot Reload disabled for projects targeting .NET 5 or earlier versions.
+
+## Previous behavior
+
+Previously, [`dotnet watch`](../../../tools/dotnet-watch.md) automatically disabled Hot Reload when used with projects targeting .NET 5 or earlier.
+
+## New behavior
+
+Starting in .NET 9, an error is reported when [`dotnet watch`](../../../tools/dotnet-watch.md) is launched without `--no-hot-reload` for projects targeting .NET 5 or earlier versions. The error is similar to:
+
+> Hot Reload based watching is only supported in .NET 6.0 or newer apps.
+
+## Version introduced
+
+.NET 9 RC 1
+
+## Type of breaking change
+
+This change is a [behavioral change](../../categories.md#behavioral-change).
+
+## Reason for change
+
+The internal architecture of the `dotnet watch` tool underwent significant improvements. Preserving behavior for out-of-support .NET versions did not warrant increasing the complexity of the new implementation.
+
+## Recommended action
+
+Pass `--no-hot-reload` to `dotnet watch` on the command line, or update your project to target `net6.0` or later (using the `TargetFramework` property).
