System.InvalidOperationException: Unable to genera

Question

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?

Answer 1

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

Answer 2

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

Answer 3

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.

Answer 4

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.

Answer 5

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).

Answer 6

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.
