Issue: I have a.Net Core 3.0 app that I'm unable to load in a browser ONLY when running it using the Mac OS X CLI, like so: $ dotnet new webapp $ dotnet watch run watch: Started info: Microsoft.AspNetCore.DataProtection.KeyManagement.XmlKeyManager0 User profile is available.
The runtime is used to run apps created with.NET Core. When an app author publishes an app, they can include the runtime with their app. If they don't include the runtime, it's up to the user to install the runtime. There are three different runtimes you can install on macOS: ASP.NET Core runtime. I was able to compile my project and execute it. Is there any way to remove to dlls i dont need? There is a Microsoft.CodeAnalysis.VisualBasic.dll. I would like to have a smaller sized version. After publish i get a 46 MB folder for my little app:) – dknaack Aug 5 '16 at 15:30. So, What is Microsoft.NETCore.App anyways? 09 June 2016 by Micheal Colhoun. Getting my head clear on the new ASP.NET Core platform is taking a lot longer than I anticipated. A lot has to do with dotnet core going cross platform and having to support many different eco systems. NET Core is made up of the runtime and the SDK. The runtime is used to run a.NET Core app and may or may not be included with the app. The SDK is used to create.NET Core apps and libraries. The.NET Core runtime is always installed with the SDK. The Office apps available from the Mac App Store provide the very latest version of Office on the Mac. Word, Excel, PowerPoint, and Outlook require a Microsoft 365 subscription to activate. OneNote and OneDrive do not require a Microsoft 365 subscription, but some premium features may require a Microsoft 365 subscription. Building a.NET Core single exe for Linux on macOS or Windows. Run the.NET Core SDK docker image and share your working directory containing your.csproj file at /home in the container.
.NET Core 2.2.7 is available for download and usage in your environment. This release includes .NET Core 2.2.7, ASP.NET Core 2.2.7 and updates to the .NET Core SDK.
We've created an issue at dotnet/core #3345 for your questions and comments.

Changes in 2.2.7
.NET Core 2.2.7 release carries both security and non-security fixes.
CVE-2019-1302: ASP.NET Core Elevation Of Privilege Vulnerability
Microsoft is releasing this security advisory to provide information about a vulnerability in ASP.NET Core. This advisory also provides guidance on what developers can do to update their applications to remove this vulnerability.
Microsoft is aware of an elevation of privilege vulnerability exists when a ASP.NET Core web application, created using vulnerable project templates, fails to properly sanitize web requests. An attacker who successfully exploited this vulnerability could perform content injection attacks and run script in the security context of the logged-on user.
To exploit the vulnerability, an attacker could send a specially crafted email, containing a malicious link, to a user. Alternatively, an attacker could use a chat client to social engineer a user into clicking the malicious link. However, in all cases to exploit this vulnerability a user must click a maliciously crafted link from an attacker.
The update addresses the vulnerability by correcting how the .NET Core web application handles content encoding and updates the application templates to depend on the corrected code libraries.

Affected Package and Binary updates
| Package name | Vulnerable versions | Secure versions |
|---|---|---|
| Microsoft.AspNetCore.SpaServices | 2.1.0-2.1.2 2.2.0 | 2.1.2 2.2.1 |
CVE-2019-1301: Denial of Service Vulnerability in .NET Core
Microsoft is releasing this security advisory to provide information about a vulnerability in .NET Core. This advisory also provides guidance on what developers can do to update their applications to remove this vulnerability.
Microsoft is aware of a denial of service vulnerability when .NET Core improperly handles web requests. An attacker who successfully exploited this vulnerability could cause a denial of service against a .NET Core web application. The vulnerability can be exploited remotely, without authentication.
The update addresses the vulnerability by correcting how the .NET Core web application handles web requests.

###CVE-2018-8269: Denial of Service Vulnerability in OData
Microsoft is releasing this security advisory to provide information about a vulnerability in ASP.NET Core. This advisory also provides guidance on what developers can do to update their applications to remove this vulnerability.
Microsoft is aware of a denial of service attack in the Microsoft OData library used in ASP.NET could cause a denial of service against an OData web application. A remote unauthenticated attacker could exploit this vulnerability by issuing specially crafted requests to the OData application.
The update addresses the vulnerability by updating the version of OData ASP.NET Core uses.
