[SOLVED] .Net 8 Publish configuration - Trying to add the IIS requestFiltering option to our pubxml

.Net 8 Publish configuration - Trying to add the IIS requestFiltering option to our pubxml

We recently came across an issue where a specific front end feature was blocking file uploads, where the file was greater than 30MB (Angular front end, and .Net 8 API).

In the past we had the web.config, but the current approach is appsettings.json.

In the older web.config, we had the following requestLimits property:

<system.webServer>
 <security>
   <requestFiltering>
     <requestLimits maxAllowedContentLength="2147483648" />
     </requestFiltering>
 </security>
</system.webServer>

which can NO LONGER be added to appsettings.json in .Net 8 projects.

So, the question is: how can we build this requestFiltering section into the web.config at Publish time.

Here is an example of FolderProfile.pubxml in our project:

<?xml version="1.0" encoding="utf-8"?>
<!--
https://go.microsoft.com/fwlink/?LinkID=208121.
-->
<Project>
  <PropertyGroup>
    <DeleteExistingFiles>false</DeleteExistingFiles>
    <ExcludeApp_Data>false</ExcludeApp_Data>
    <LaunchSiteAfterPublish>true</LaunchSiteAfterPublish>
    <LastUsedBuildConfiguration>Release</LastUsedBuildConfiguration>
    <LastUsedPlatform>Any CPU</LastUsedPlatform>
    <PublishProvider>FileSystem</PublishProvider>
    <PublishUrl>bin\Release\net8.0-windows8.0\publish\</PublishUrl>
    <WebPublishMethod>FileSystem</WebPublishMethod>
    <_TargetId>Folder</_TargetId>
  </PropertyGroup>
</Project>

Is this something that can be somehow injected into the web.config at build time or publish time ?

Solution

Try placing the web.config with only the needed lines in your project.
