ASP.NET strange compilation error

ASP.NET strange compilation error

回答1

I removed Roslyn related packages by NuGet and it does work now.

Roslyn related packages:

• Microsoft.CodeDom.Providers.DotNetCompilerPlatform
• Microsoft.Net.Compilers

P.S: My local IIS doesn't have any problem with Roslyn but as I publish the project on the server (this is why I don't think the server supports Roslyn), it shows the following error message:

Compilation Error

Description: An error occurred during the compilation of a resource required to service this request. Please review the following specific error details and modify your source code appropriately.

Compiler Error Message: The compiler failed with error code -532462766.

OK, after days struggling with this issue, I finally fixed it.

• Not by clearing ASP.NET temp
• Not by reinstalling the .NET framework!

Simple!

• I changed the application pool identity from "Local system" to "ApplicationPoolIdentity"

Apparently there was a permission error with my local system that the C# compiler (csc.exe) could not access some resources and source codes.

In order to change your AppPool identity follow steps given here: http://learn.iis.net/page.aspx/624/application-pool-identities/

What worked for me... It seems if you install (or a dependent package installs) Microsoft.CodeDom.Providers.DotNetCompilerPlatform NuGet package it makes some web.config transforms that allow you to use C#7.x features in ASP.NET Razor pages. Whilst I found these worked fine on my local machine they didn't work on our server (even when the compiler was in the /bin/ folder).

The solution was to locate the element below and remove completely from web.config

  <system.codedom>
    <compilers>
      <compiler language="c#;cs;csharp" extension=".cs" type="Microsoft.CodeDom.Providers.DotNetCompilerPlatform.CSharpCodeProvider, Microsoft.CodeDom.Providers.DotNetCompilerPlatform, Version=1.0.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35" warningLevel="4" compilerOptions="/langversion:6 /nowarn:1659;1699;1701" />
      <compiler language="vb;vbs;visualbasic;vbscript" extension=".vb" type="Microsoft.CodeDom.Providers.DotNetCompilerPlatform.VBCodeProvider, Microsoft.CodeDom.Providers.DotNetCompilerPlatform, Version=1.0.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35" warningLevel="4" compilerOptions="/langversion:14 /nowarn:41008 /define:_MYTYPE=\&quot;Web\&quot; /optionInfer+" />
    </compilers>
  </system.codedom>

I have crawled through a lot of blog posts including a few Stack Overflow pots, and I already had everything in place what these posts suggested (see below) when I got this error.

1. My app pool is running under ApplicationPoolIdentity
2. Load user Profile was set to True in Process Model section
3. IIS AppPool\DefaultAppPool has full permissions on temp ASP.NET files folder

Finally I found some clues in the below mentioned blog post. It looks like there is heap contention with the same user account. So I changed the app pool identity to LocalSystem, for the app which is failing with this error - and my app started working fine.

See blog post C# compiler or Visual Basic .Net compilers fail with error code -1073741502 when generating assemblies for your ASP.net site.

Note: LocalSystem account will not have much permissions. In my case my application does not need any special permissions. So I was fine. If your application needs special permissions try configuring a custom account.
