We are seeing this error randomly when compiling a big Winforms project. On Rebuild All this goes away. However I am seeing this many times throughout the day.

The Visual Studio is 2008 SP1 We are using WinXP SP3 and DevExpress Winforms controls in a SCSF project. LLBLGen version is version 3 - July 02, 2010.

Any clue why this is happening?

Looks like somewhere you referenced a v2.6 version of the ormsupportclasses as well?

Hi Otis,

I suspect that may not be true. I will double check just in case I missed it. Actually all the DLLs are in a single folder on this machine.

Further if it was that, then why would the clean rebuild fix it?

It's midnight here. Will let you know tomorrow morning.

I second what Frans said. Most probably this is a version mismatch issue, where you have 2 versions of the ORMSUpportClasses referenced in your solution.

Most probably the generated code references one version while your application references the other.

Nah. This machine is a clean machine with fresh Windows/VS2008sp1 install. We fetch the source (including the ORMSUpportClasses DLL) via SVN. Even searched on the system. Only version 3 DLLs.

Here's more detail. We have an address control. When we add the address control the RESX is getting some bad data. For trial we commented the section in resx of a form where we have this control and then we are not seeing this error.

See the two data sections commented.

<?xml version="1.0" encoding="utf-8"?>
<root>
  <!-- 
    Microsoft ResX Schema 
    
    Version 2.0
    
    The primary goals of this format is to allow a simple XML format 
    that is mostly human readable. The generation and parsing of the 
    various data types are done through the TypeConverter classes 
    associated with the data types.
    
    Example:
    
    ... ado.net/XML headers & schema ...
    <resheader name="resmimetype">text/microsoft-resx</resheader>
    <resheader name="version">2.0</resheader>
    <resheader name="reader">System.Resources.ResXResourceReader, System.Windows.Forms, ...</resheader>
    <resheader name="writer">System.Resources.ResXResourceWriter, System.Windows.Forms, ...</resheader>
    <data name="Name1"><value>this is my long string</value><comment>this is a comment</comment></data>
    <data name="Color1" type="System.Drawing.Color, System.Drawing">Blue</data>
    <data name="Bitmap1" mimetype="application/x-microsoft.net.object.binary.base64">
        <value>[base64 mime encoded serialized .NET Framework object]</value>
    </data>
    <data name="Icon1" type="System.Drawing.Icon, System.Drawing" mimetype="application/x-microsoft.net.object.bytearray.base64">
        <value>[base64 mime encoded string representing a byte array form of the .NET Framework object]</value>
        <comment>This is a comment</comment>
    </data>
                
    There are any number of "resheader" rows that contain simple 
    name/value pairs.
    
    Each data row contains a name, and value. The row also contains a 
    type or mimetype. Type corresponds to a .NET class that support 
    text/value conversion through the TypeConverter architecture. 
    Classes that don't support this are serialized and stored with the 
    mimetype set.
    
    The mimetype is used for serialized objects, and tells the 
    ResXResourceReader how to depersist the object. This is currently not 
    extensible. For a given mimetype the value must be set accordingly:
    
    Note - application/x-microsoft.net.object.binary.base64 is the format 
    that the ResXResourceWriter will generate, however the reader can 
    read any of the formats listed below.
    
    mimetype: application/x-microsoft.net.object.binary.base64
    value   : The object must be serialized with 
            : System.Runtime.Serialization.Formatters.Binary.BinaryFormatter
            : and then encoded with base64 encoding.
    
    mimetype: application/x-microsoft.net.object.soap.base64
    value   : The object must be serialized with 
            : System.Runtime.Serialization.Formatters.Soap.SoapFormatter
            : and then encoded with base64 encoding.

    mimetype: application/x-microsoft.net.object.bytearray.base64
    value   : The object must be serialized into a byte array 
            : using a System.ComponentModel.TypeConverter
            : and then encoded with base64 encoding.

Would it be possible for you to attach the entire solution so that we can try it for our selves...?

Does this happen on more than one machine...?

No. Its not possible to provide entire solution. This is a big application and contains our proprietary code and algorithms.

Yes this is happening on multiple machines. All the machines are configured in exactly the same way. However I do not thing it is the machine config.

Thanks

No. Its not possible to provide entire solution. This is a big application and contains our proprietary code and algorithms.

Could you please provide a simple repro solution? Coz we can't reproduce it over here.

Sorry but I can't. Even we cannot reproduce this here except our project. I guess we will need to keep this as a dead duck.

Thanks

We will mark this as done for now. Please come back if you can give us some steps to reproduce it consistently or even better, a tiny repro solution.

The resx files have types dragged onto the control binary serialized inside them. This might be the problem. Also where the exception occurs, you might try to set a breakpoint and in the debugger try to obtain the codebase property of the assemblies of both types which apparently aren't the same.

Though I think it's the types onto the control / form (e.g. an entity collection) which are tied to a specific assembly and serialized as such into the resx file, otherwise I don't know.
