React website with ASP.NET and IIS : API not working
Hi, I have found a lot of similar issues on the web but none was working for me, and I am so desperate after days so I am posting here and hope someone can help. I have an ASP.NET server that serves a React website, and also works as an API for the website itself. The server runs on a Windows 11 PC with IIS, in C:/MyWebSite. This folder contains the ASP.NET server (.exe, .dll, etc), the IIS configuration (web.config) and the build React website (index.html, favicon.ico and assets folder). The server succeed to show my main page, but it fails doing an API request. The API request fails as well when I call it from Postman, and gives me the error "HTTP 404.0 - Not Found" with these details : Module IIS Web Core Notification : MapRequestHandler Handler : StaticFile Error code : 0x80070002 FYI, the request is GET http://localhost:5058/api/configuration/settings Concerning ASP.NET, here is my Program.cs : using Microsoft.AspNetCore.Authentication.JwtBearer; using Microsoft.IdentityModel.Tokens; using System.Text; // Create the web application builder var builder = WebApplication.CreateBuilder(args); // JWT authentication builder.Services.AddAuthentication(options => { options.DefaultAuthenticateScheme = JwtBearerDefaults.AuthenticationScheme; options.DefaultChallengeScheme = JwtBearerDefaults.AuthenticationScheme; }) .AddJwtBearer(options => { string? tKey = builder.Configuration["Jwt:Key"]; options.TokenValidationParameters = new TokenValidationParameters { ValidateIssuer = true, ValidateAudience = true, ValidateLifetime = true, ValidateIssuerSigningKey = true, ValidIssuer = builder.Configuration["Jwt:Issuer"], ValidAudience = builder.Configuration["Jwt:Audience"], IssuerSigningKey = tKey != null ? new SymmetricSecurityKey(Encoding.UTF8.GetBytes(tKey)) : null }; }); // Add the controllers to the application (for input http requests) builder.Services.AddControllers(); // Configure CORS policy builder.Services.AddCors(options => { options.AddPolicy("AllowAllOrigins", builder => { builder.AllowAnyOrigin() .AllowAnyHeader() .AllowAnyMethod(); }); }); // Create the App var app = builder.Build(); // Applies the CORS policy app.UseCors("AllowAllOrigins"); // Serving the static files app.UseDefaultFiles(); app.UseStaticFiles(); app.UseRouting(); // Map the routes to the controllers app.MapControllers(); // Undefined route will lead to index.html app.MapFallbackToFile("index.html"); // Run the App app.Run(); Of course, I have created some controllers, here is ConfigurationController.cs for example : using Microsoft.AspNetCore.Mvc; namespace AspReact.Server.Controllers { [ApiController] [Route("api/configuration")] public class GeneralController : ControllerBase { [HttpGet("settings")] public ActionResult GetSettings() { return Ok(new { language = 'fr', theme = 0 }); } [HttpPost("settings")] public ActionResult SetSettings([FromQuery] string language, [FromQuery] string theme) { m_tLanguage = language; m_tTheme = theme; return Ok(); } } } Here is my IIS configuration : <?xml version="1.0"?> <configuration> <system.webServer> <rewrite> <rules> <rule name="React Routes" stopProcessing="true"> <match url=".*" /> <conditions logicalGrouping="MatchAll"> <add input="{REQUEST_FILENAME}" matchType="IsFile" negate="true" /> <add input="{REQUEST_FILENAME}" matchType="IsDirectory" negate="true" /> <add input="{REQUEST_URI}" pattern="^/(api)" negate="true" /> </conditions> <action type="Rewrite" url="/" /> </rule> </rules> </rewrite> </system.webServer> </configuration> NB : At first I was not doing : <add input="{REQUEST_URI}" pattern="^/(api)" negate="true" /> And the API request was returning the content of index.html... If it can help. Please note that all this is working during development with the server running in a debug console. I would be grateful for any help! Thanks.Solved86Views0likes2Comments
Dynamic form generation from dictionary
ASP.NET Blazor app brand spanking new to the stuff here. Trying a move from Apache PHP. Trying to create a dynamic form from a dictionary generated from a separate class I've banged my head against the wall for hours and can't get past this point.

ajax and connection to mvc .net
I need to access some c# code from javascript in MVC ,NET (not blazor). I have the below. This is very specific to .NET and MVC stack and not a generic ajax question like another one in stack overfow. I get no error message it just continues to the next statement after the ajax call. There could be 2 possible issues i think. My url: '/Home/CreatePostcodeFromCoordinates', is wrong. Or my C# assembly is not part of the assembly? or something similar. I am not that experienced with Web techs, I come from a DB background but can't be that difficult to get this link working right? Can't see anything else wrong. Also does the return value from C# need to be some special format or a string (as per now) is ok? this could be another reason? Thank you! console.log("just before /Home/CreatePostcodeFromCoordinates"); $.ajax({ type: "POST", url: '/Home/CreatePostcodeFromCoordinates', data: { param1: longitude, param2: latitude }, success: function (response) { console.log('success'); console.log(response); }, error: function (error) { console.error(error); } });Solved107Views0likes1Comment
Checkbox values empty if other form fields are empty when POST form
I have hit a road block on a ASP.NET/Razor Pages project I am working on. I have a form with checkboxes. I have a List<int> field that is bound to the Id of the checkboxes. If I submit the form with only the checkboxes checked the List is always null. However, if I type text in a textbox in the form before submitting, the checkbox values are POST'd correctly. Looking for any hints on things to try or check to to help me narrow down the problem. Thank for any suggestions.Solved236Views0likes2CommentsEF Core : foreign key column with same name as existing navigation property
Iwant to use EF Core to map a legacy database. I cannot scaffold as there are hundreds of tables and I am only interested in very few and besides scaffolding generates names for the navigation properties which are not the ones I want. The situation is: I have a required many-to-one relationship linked by a column name that matches the name of the property that I want to give. The code (simplified) is: public class EntityProperty { public ControlType ControlType { get; set; } } public class ControlType { public List<EntityProperty> Properties { get; set; } = new List<EntityProperty>(); } Nothing more is required, eg, I'm not using foreign key properties, just navigation. The problem is, the foreign key column from theEntityPropertiestable to theControlTypesis also calledControlType. So, when I try to map it as: builder.HasOne(x => x.ControlType) .WithMany(x => x.Properties) .IsRequired() .HasForeignKey("ControlType"); I want to use EF Core to map a legacy database.

The problem is with HasForeignKey, I guess it's because I am adding a shadow property when a "physical" property already exists, but I what I really mean to say is to use a different column name to link the two entities: what I want is to be able to specify a "not standard" column name for the foreign key, which I am not able to. I do not have a foreign key property, only a navigation property, and I do not want to have one.Solved1.7KViews0likes1CommentMSB4011 warnings

If you create a Windows Forms project in Visual Studio 2022, it creates a Form1.cs file, a Form1.cs [Design] form, and a Form1.Designer.cs file. You can then drag items from the toolbox onto the form or select the form and using the form properties window to add event handlers like OnPaintForm1, and the Designer will handle those actions appropriately. However, if after creating the project, you immediately rename Form1.cs and its counterparts to, say, MyForm.cs, etc. and then drag items from the toolbox to the form or select the form and use the properties window to add event handlers, the Designer does not appropriately update the renamed form files or form design. What I have to do is use the original Form1 files, add the tools and event handlers, and build the application. After that, I can rename the files and they still work.

So I have a C# app that reads from Excel (using Microsoft.ACE.OLEDB.12.0) in order to then add those rows into a larger consolidated sheet. It's worked fine for a long time. Suddenly the past couple of weeks I received trouble reports from endusers that the app isn't functioning. When I debugged it, seems that the Excel source files have zero rows read. No runtime errors or anything. I have verified that the column headings are correct, against theOleDbCommand.CommandText query. And the column headings are based on a generic template that all of these source sheets use. The source sheets have rows of valid data. A year or two ago I recall there was a Windows Update that affected some of these Excel OLEDB operations. Due to MDAC era components being deprecated. Hence why I changed over to ACE OLEDB 12.0. Since I did that this app has run without fail. Anyone know if there was indeed a Windows Update that would've affected things? Running this on Windows 10 Pro.

PrimitiveDataFrameColumn<DateTime> dateTimeCol = new("Dates", 0); // Fill it. dateTimeCol.Append(DateTime.Now + TimeSpan.FromDays(1)); dateTimeCol.Append(DateTime.Now + TimeSpan.FromDays(2)); dateTimeCol.Append(DateTime.Now + TimeSpan.FromDays(3)); // Create a Ticks column. PrimitiveDataFrameColumn<long> ticksCol = new("Ticks", dateTimeCol.Length); // Create a DataFrame of the above two columns. DataFrame df = new(); df.Columns.Add(dateTimeCol); df.Columns.Add(ticksCol); At this point, what I want to do isdf["Ticks"] = df["Dates"].Ticks. Of course, this doesn't work. I could do this: for (int i = 0; i < df.Rows.Count; i++) { DateTime tempDate = (DateTime) df[i, df.Columns.IndexOf("Dates")]; df[i, df.Columns.IndexOf("Ticks")] = tempDate.Ticks; } But... is there a better way?Solved2.5KViews0likes4Comments
