On an ASP.NET Core 2.0 application I need to render a partial view and pass a few parameters: @Html.Partial("Form", new { File = "file.pdf" }) On the partial view I tried to access it using: @Model.File And I get the error: RuntimeBinderException: 'object' does not contain a definition for 'File' If I simply use on my partial: @Model I get the following printed on the page: { File = file.pdf } So there the model is being passed and there is a property File in it.

问题 With the recent release of .NET Core 1.0, we're in the process of migrating our RC1 applications to the final release.

Previously in the RC1 applications, we had used the System.DirectoryServices.AccountManagement library to handle the LDAP authorization queries. However, we can no longer mix this library with .NET Core v1. Generally, what is the best way to integrate Active Directory

Read appsettings.json in Main Program.cs

阅读更多关于 Read appsettings.json in Main Program.cs

First of all my main purpose is to setup the IP and Port for my application dynamically. I'm using IConfiguration to inject a json config file, like some tutorial mentioned. However, I can't retrieve the configuration in Program.cs, because my WebHostBuilder will use the StartUp and Url at the same time. So at the time the host build up, there is nothing in my configuration. WebProtocolSettings settings_Web = new WebProtocolSettings(); var host = new WebHostBuilder() .UseIISIntegration() .UseKestrel() .UseContentRoot(Directory.GetCurrentDirectory()) .UseStartup<Startup>() .UseUrls(settings_Web

I also do not want to use the IIS built in support for Basic authentication , since it uses the Windows credentials. ASP.NET Security will not include Basic Authentication middleware due to its potential insecurity and performance problems. If you require Basic Authentication middleware
