问题 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.

RequireHttpsAttribute with .NETCore RC2 causes HTTP302 redirect loop on Azure

阅读更多关于 RequireHttpsAttribute with .NETCore RC2 causes HTTP302 redirect loop on Azure

I've been trying to get a .NETCore RC2 web app working on Azure with the RequireHttpsAttribute set but I'm having issues. To remove the possibility of this being a problem that I've introduced with my code, I cut things back to the bare minimum and recreated it using the "out of box" VS2015 .NETCore RC2 template. If I deploy the standard VS2015 .NETCore RC2 web app the site runs fine. If I then add [RequireHttps] to the controllers it works fine locally, but on Azure it causes an HTTP302 redirect loop. This seems to be something which has changed since RC1 since the RequireHttpsAttribute works

阅读更多关于 EntityFramework code first: Set order of fields

问题 I am using EntityFramework with the "Code first" approach with migrations. I have successfully generated tables from my models, but the columns are being added in an alphabetical order rather than the order inside my model. I have tried this: [Key, Column(Order=0)] public int MyFirstKeyProperty { get; set; } [Column(Order=1)] public int MySecondKeyProperty { get; set; } But that doesn't seem to be working. How can I manually set the order of the fields in the database? I am using ASP.NET Core

问题 I have created an mvc site and I'm posting a large amount of json form data ( Content-Type:application/x-www-form-urlencoded ) back to the mvc controller. When I do this, I receive a 500 response that states: "InvalidDataException: Form value count limit 1024 exceeded."

So at the time the host build up, there is nothing in my configuration. WebProtocolSettings settings_Web = new WebProtocolSettings(); var host = new WebHostBuilder() .UseIISIntegration()
