The exception seems to be thrown by System.Linq.Expressions.Compiler.LambdaCompiler.Compile. Do you have more exception details, such as exception type and exception message?

dotnetjunkie avatar Jun 30 '21 19:06 dotnetjunkie

Is there a command I can put in WinDb to get that? All I used was !analyze -v. This issue was reported by LeanSentry.

cblaze22 avatar Jun 30 '21 20:06 cblaze22

I'm not that familiar with windbg. Can't help you with that.

dotnetjunkie avatar Jun 30 '21 20:06 dotnetjunkie

Ok let me dig deeper

cblaze22 avatar Jun 30 '21 20:06 cblaze22

The issue you are having sounds familiar, but the last time issues like these were reporting were when Dynamic Assembly Compilation (DAC) was on by default. For more details, see #274. From the stack trace, however, it seems you have DAC turned off. Perhaps there is another tool that uses DAC, which corrupts the IIS process, which also impacts Simple Injector?

dotnetjunkie avatar Jul 14 '21 20:07 dotnetjunkie

It says Options.EnableDynamicAssemblyCompilation is obsolete. So should it still be used?

cblaze22 avatar Jul 14 '21 21:07 cblaze22

Setting that property has no effect any longer. To enable DAC, you need to pull in the SimpleInjector.DynamicAssemblyCompilatipn NuGet. If you're not using that extra NuGet, you're not using DAC on Simple Injector. Other libraries, however, might still do DAC.

dotnetjunkie avatar Jul 14 '21 21:07 dotnetjunkie

In the past, these kinds of issues would typically occur when Simple Injector's dynamic compilation feature was used in combination with tools like:

  • Microsoft IntelliTrace
  • JetBrains dotTrace
  • Microsoft's test runner (MSTest)
  • TestDriven.NET
  • .NET profiling API (which seems what all the above tools rely on)

Simple Injector's Dynamic Assembly Compilation feature has been disabled by default since version 3.3 and after that point error reports stopped.

I remember seeing these crashes happen once or twice in combination with IIS recycling an app domain, but I believe this was still in combination with other tooling. Did anything change on your server before you experienced the first crash of this kind? Was any kind of monitoring tooling installed that might interact with the app domain? Profiling tooling perhaps?

Also consider the following issues, because they might be related:

  • https://github.com/dotnet/runtime/issues/10275
  • https://github.com/dotnet/efcore/issues/11543

Are you sure its calling a DAC path because the screenshot below starts at the .Verify method. Seems that is a normal default thing to do.

cblaze22 avatar Nov 01 '21 13:11 cblaze22

Are you sure its calling a DAC

No, I'm pretty sure that your code doesn't use DAC as it is using the DefaultExpressionCompilationBehavior, which simply calls System.Linq.Expressions.Compiler.LambaCompiler.Compile. This uses Lightweight Code Generation (LCG) (a.k.a. dynamic methods), which is different from Dynamic Assembly Compilation (although both can be achieved through the Expression API).

my experience is that LCG does usually not cause the issues you are having, but there are exceptions, as the previous Microsoft issues show.
