System.InvalidOperationException: Unable to generate a temporary class (result=1)

C#Input

C# Problem Overview

I have developed an application using .net 3.5 and have deployed it as an .exe on a number of machines with the same environment. However, on one particular machine I get the following error. Stack Trace:

See the end of this message for details on invoking just-in-time (JIT) debugging instead of this dialog box.

************** JIT Debugging ************** To enable just-in-time (JIT) debugging, the .config file for this application or computer (machine.config) must have the jitDebugging value set in the system.windows.forms section. The application must also be compiled with debugging enabled.

For example:

When JIT debugging is enabled, any unhandled exception will be sent to the JIT debugger registered on the computer rather than be handled by this dialog box.

Could someone help me with this?

As I am new to .net could someone also tell me when why a temporary class needs to be created in the first place?

C# Solutions

Solution 1 - C#

I just spent a lot of time searching for the answer to this so I thought I'd add it here to save some headache for others. If you use the xsd.exe tool to generate your cs it may have added double arrays [][] where an array should be []. Replace all [][] with [] in your generated cs file and retry.

Solution 2 - C#

XML Serialisation works by generating code to perform the serialisation. This is done in a temporary assembly created for that purpose the first time it is needed.

However this relies on being able to write the assembly to disk.1

Your options are either to (1) given the user account which is running the process write permission (for an ASP.NET application this is likely to be a bad idea). (2) Use the SDK tool (sgen.exe) to pre-generate (at development/compile time) the serialisation assembly, and then use (and deplot) that assembly.

1Open question: the APIs exist to create assemblies dynamically in memory: why not do that?

Solution 3 - C#

You only have to give the List Folder Contents and Read permissions on %windir%\Temp.

I found this post when trying to fix my problem, and didn't have to give my user account write access.

From Microsoft

Solution 4 - C#

You Need to give the permission to the temp folder which is in windows folder. And Your Problem is Solved...........

Solution 5 - C#

You need to add IIS_IUSR user with read write permission to C:\Windows\Temp folder.

NOTE: Everyone user will not work with full control.

Solution 6 - C#

Surfacing @grzenio's comment a bit further for recent users:

If you go to Project Properties -> Build -> Generate serialization assembly -> On, it forces the generation of the XML serializers assembly at compile time, eliminating the need to do so at runtime.

In turn, this means you don't need to change filesystem permissions (useful if you're, for example, hosting on Windows Azure Web Sites, where that isn't an option).

Solution 7 - C#

It may be also just some simple error in the serialized class (typically a result of some copy/paste). For example the following class will cause this error:

  public class Foo
  {
      private string[] contexts;

      /// <remarks/>
      [System.Xml.Serialization.XmlArrayItemAttribute("Context", 
       typeof(Property), IsNullable = false)]
      public string[] Contexts
      {
          get { return this.contexts; }
          set { this.contexts = value; }
      }
  }

Notice that typeof(Property) parameter in XmlArrayItem attribute is not compatible (most likely) with string causing similar exception:

System.InvalidOperationException: 
Unable to generate a temporary class (result=1).

If typeof(Property) is replaced with typeof(string) serialization will work again.

Solution 8 - C#

> the APIs exist to create assemblies dynamically in memory: why not do that?

Just a wild guess: I assume this possibility did not exist yet in .NET 1.0, or at least when the XmlSerializer was created and MS doesn't like changing existing behavior...

Solution 9 - C#

Give Read/Write Privileges to 'C:\WINDOWS\TEMP' folder. It will work.

Solution 10 - C#

It may be bacause you are switching application pooling identity in IIS to be password instead of predefined so you have one off the following

  1. return to predefined
  2. give prmission full control to user IWAM_WBSRV-01 on the windows temp folder

Solution 11 - C#

In case this helps anyone, my problem was coming from an inherited class used in the serialization. The problem went away when I made a full copy/paste of my class I was serializing and quit using ineritance. Unfortunately, the advantages of inheritance went away, but that is better than having this problem. (Hey, at least I'm pretty sure that's what solved it. Happened to do a reboot in there somehwere too.)
