Hey friends, as I have promise you to come up with new things in web stack, I have decided to write on ASP.NET beta 7 release.
Microsoft has just released ASP.NET beta 7 as a NuGet Package, it also include tooling update for VS 2015 RTM. With this release announcement Microsoft has also announce its first public preview of the DNX.
What is DNX?
There is an obvious question for new developers about DNX. DNX is .NET Execution Environment for .NET core on Linux and Mac machines. DNX is independent execution environment and you don’t need Mono anymore to build and run the application in Linux and Mac.
Improvements and bug fixes in ASP.NET 5 beta 7
With the new release, there is obvious new features and some bug fixes. You can find then in following sections.
In scenario mention in the article, the error message says that required anti-forgery cookie “
__RequestVerificationToken” is not present and it mention the form field. Now they fixed that with appropriate error message.
ASP.NET beta 7 now supports following Caching
- Output caching
- In memory cache
- Distributed cache
- Using Redis
There was some architectural changes after BCL API review and rename some names. They also fix issue that
ConfigurationBinder throw a
TargetParameterCountException. You can find more about the issue on GitHub.
CORS (Cross-Origin Resource Sharing)
To prevent malicious sites from accessing your data and page content from another site and that restriction is called Same-Origin request. Cross-Origin Request was also prevented in the case of AJAX call. However, sometimes you are in a need to give access or let another site to access or make Cross-Origin Requests.
CORS (Cross-Origin Resource Sharing) is a w3c standard, and server let specific site make Cross-Origin Request and say good bye to Same-Origin Request policy, but intact for another site. This technique is also powerful and flexible than JSONP.
Now a day e-Commerce is bursting and sites are storing more sensitive information than banks, hence data protection is more important for security reasons. Microsoft Window has support for DPAPI for the desktop application, but this is unsuitable for web stack. So, ASP.NET has Data Protection API to protect web data with more reliable and secure way with key encryption, management, and rotation.
There was some improvements and bug fixes in Dependency Injection that you can found at GitHub. With the addition to that you can get better error message with incompatible package dependencies.
ASP.NET 5 come up with new features Diagnostics API that help developer to diagnose issues in development and production environment. Now you can configure it in
Configure() method inside
Startup class. You have ability do display less information in production and descriptive error messages for production environment by controlling error page and
Now, You can also configure runtimeinfo page by simply calling
UseRuntimeInfoPage extention method in Startup class. After adding runtimeinfo page you can browse /runtimeinfo page to look at your ASP.NET runtime information.
.NET SDK Version manager is use full to manage DNX. DNVM has a set of command line utilities to configure .NET runtime version on Linux and MAC environment.
This topic required more attention as DNX very helpful to run your code into Linux and MAC environment. There is lots of improvement and bug fixes that you can find at GitHub.
With the release of ASP.NET beta 7 there was new feature that reverse engineer model from database and convention based model builder support for Data Annotations, which includes following attributes to be implemented.
There was also some relational attributes
There was not support for complex types yet.
Still, There is lot more in release of ASP.NET beta 7, hence I have divided this post into couple of post and shortly I will come up with rest of features that released with ASP.NET beta 7. Thank you.
