I am trying to run a simple ASP.NET application in a Docker Container. Unfortunately, this application is a .NET Framework (not .NET Core), and because of that, I need to run in Windows Containers.

I created a very basic ASP.NET App, and I use a Dockerfile exact as described in the docker image documentation. The build went successfully, and I used the command docker run -it --rm -p 8001:80 container_name to run the container.

When I tried to access the page, I got the following error:

Access to the path 'C:RoslynCompilers-3.6.0toolscsc.exe' is denied.

After some google search, I found that a solution would change the OutputPath to bin1 (or anything different from bin), but, instead, I got an error different:

Configuration Error

That seems to be a missing detail in the configuration or the build process, but as I don’t have much experience with .NET, I fail to find the solution.

If it helps, my package config:

<?xml version="1.0" encoding="utf-8"?>
<packages>
  <package id="Antlr" version="3.5.0.2" targetFramework="net48" />
  <package id="bootstrap" version="3.4.1" targetFramework="net48" />
  <package id="jQuery" version="3.4.1" targetFramework="net48" />
  <package id="Microsoft.AspNet.Mvc" version="5.2.7" targetFramework="net48" />

  <package id="Newtonsoft.Json" version="12.0.2" targetFramework="net48" />
  <package id="WebGrease" version="1.6.0" targetFramework="net48" />
</packages>

And my project.csproj.

I had the same issue with Docker Desktop 4.7.1. Try to downgrade to 4.7.0. It helped in my case.

I solved this issue by making sure the base image referenced in my dockerfile matched my Windows OS install. In my case:
```
FROM mcr.microsoft.com/dotnet/framework/aspnet:4.8-windowsservercore-ltsc2022
```
