问题 I have an ASP.NET Core MVC app attempting to upload an IFormFile. However, the IFormFile is always null. None of the other solutions I've found have solved this issue. What am I doing wrong? Model public class EmailForm { [Display(Name = "Add a picture")] [DataType(DataType.Upload)] [FileExtensions(Extensions = "jpg,png,gif,jpeg,bmp,svg")] public IFormFile SubmitterPicture { get; set; } } Controller public async Task<ActionResult> Contribute([Bind("SubmitterPicture")] EmailForm model) { if

问题 Have a look at this code: var callbackUrl = Url.Page("/Account/ConfirmEmail", null, new { userId = user.Id, code }, Request.Scheme); The result is this: http://localhost:5000/Account/Register?userId=614d16ae-4e95-4796-8d67-cb829e12585b&code=CfDJ8OeNFdnFCrtCsRU7ofatUuROudlTo%2BFQe84oAiL%2BPJSoYwGH9q1Xadg8XBbpOFg5DiRH1vDoGeQ8l3qIFHjB3NMM3ZDTlQexawj1b%2BJ7P6X3SHoBsYs7jLYwcfGQCbnk1SJA5koFkoDcWj04nsjzQlJMe8ttR0DFdi%2B6TTbWI8WkPBaS083O3aU%2BL2bbYGNwwikhrkbB0nHy4PRzK1LZuZo%3D&page=%2FAccount

问题 We have an internal JavaScript library that we'd like to share between multiple projects. Actually we are already sharing it via file copying, but this has (predictably) resulted in multiple forks of the code. The consuming projects are a mix of "full" ASP.NET (MVC and Web Forms) and ASP.NET Core MVC. (I'm planning on creating two separate packages.) Installing into ASP.NET projects seems to work fine, but I'm having problems with ASP.NET Core. Initially I had all the artifacts within a files

问题 When i try to publish the .net core app Dlls using ftp via filezilla tool it shows an error message that the file is in use by another process. It's understandable that the above message shows because the the file is used by dotnet.exe which is a separate process. To overcome the issue i have to stop the application in iis each time then upload the dlls and then restart it. Due to which a very small down time is experienced , the asp.net identity session expires and it needs rdp to the server

问题 I created an ASP.NET MVC Core (1.1.0) application using VS2015. In the dialog, I selected the option to connect to Azure AD, so VS generated the boilerplate code and, as expected, the app redirects me to Microsoft's login page, where I can login with my work&school account. Now, after the user logs in, and before serving the first page (say, /home/index) I need to get some information from the user that I have stored in a database (like the display name, the contact information such as an

问题 I would like to delete a temporary file after returning it form action. How can i achieve that with ASP.NET Core: public IActionResult Download(long id) { var file = "C:/temp/tempfile.zip"; var fileName = "file.zip; return this.PhysicalFile(file, "application/zip", fileName); // I Would like to have File.Delete(file) here !! } The file is too big for returning using memory stream. 回答1: File() or PhysicalFile() return a FileResult -derived class that just delegates processing to an executor

问题 I have a website which has subdomains such as ali.sarahah.com but if a user logs in from www.sarahah.com then goes to ali.sarahah.com the session is not saved. After searching I added the following in Startup.cs : app.UseCookieAuthentication(new CookieAuthenticationOptions { CookieDomain = ".sarahah.com" }); I found out that .AspNetCore.Identity.Application cookie domain is still showing the subdomain and not the the domain and that session problem is still there. Am I doing something wrong?
