problem using the trial of SimpleDB

I just installed the most recent AWS SDK as well as the SimpleDB Management Tools and it seems there is a version mismatch with the new Amazon SDK (see screenshot).

I tried to manually copy the latest version of the AWSSDK.dll over but when I did that, the input dialog to connect changed and I was no longer able to enter my AWS credentials.

I am sure this is probably a simple recompile, repackage. Anything you could do to facilitate this so I can continue my evaluation would be appreciated.

Thank you, Tommy Fannon

Hello Tommy,

Thanks for letting us know about this. It looks like installing the AWS SDK into the GAC is overriding our ability to load the version we need. We could recompile to get around this, but that would unfortunately cause problems for people who are using other versions of the SDK. The best solution is actually to reinstall the AWS SDK and turn off the "Install SDK into GAC" option (see screenshot) -- there's usually no reason to have a non-system library in the GAC as it's more maintainable to use private deployment for each application that needs it.

If that's not an option for you, or it doesn't solve the problem, let us know.

I seem to have a similar issue:

{"Could not load file or assembly 'AWSSDK, Version=1.0.7.0, Culture=neutral, PublicKeyToken=cd2d24cd2bace800' or one of its dependencies. The system cannot find the file specified.":"AWSSDK, Version=1.0.7.0, Culture=neutral, PublicKeyToken=cd2d24cd2bace800"}

I am following the screencast for SimpleDB Getting Started tutorial and when I execute a basic query such as "uow.Apps.Count()" I get an exception with LS unable to load the AWSSDK. Here's the code snippet:

    private static LightSpeedContext<LightSpeedModel1UnitOfWork> _context;

    public void ProcessRequest(HttpContext context)
    {
        context.Response.ContentType = "text/plain";
        context.Response.Write("Hello World<br>");


        _context = new LightSpeedContext<LightSpeedModel1UnitOfWork>("default");

        using (var uow = _context.CreateUnitOfWork())
        {
            context.Response.Write("Num of apps: " + uow.Apps.Count() + "<br>");

            App app = new App();
            app.Name = "Foo";

            uow.Add(app);
            uow.SaveChanges();

            context.Response.Write("Created new app type in SDB<br>");
        }
    }

I've installed the AWSSDK with the "Install into GAC" both checked and unchecked. My env and project settings:

• VS2012 Ultimate
• Win8 x64
• Latest AWS SDK for .Net installed successfully

Please advise, thanks.

By manually browsing and adding a reference to the (very outdated) AWSSDK.DLL that is located within the Mindscape/Tools/Designer directory, I was able to get LS a little further down the road. But, now, when I called the "uow.Add(app)" method mentioned above, I get the following error:

System.NotImplementedException was unhandled by user code HResult=-2147467263 Message=The method or operation is not implemented.

So, any ideas? I'm hopeful I can get this working as I need a fast visual prototyping tool for SimpleDB. I couldn't find any docs for the Mindscape SimpleDB tool around exactly what to include in our app.config. But, through digging and deduction, I believe the following is correct. Perhaps though it is part of the problem?

<configuration>

  <configSections>
    <section name="lightSpeedContexts" type="Mindscape.LightSpeed.Configuration.LightSpeedConfigurationSection, Mindscape.LightSpeed" />
  </configSections>


    <system.web>
      <compilation debug="true" targetFramework="4.5" />
      <httpRuntime targetFramework="4.5" />
    </system.web>



  <connectionStrings>
    <add name="Dev" providerName="AmazonSimpleDB" connectionString="Access Key=foo;Secret Access Key=foo"/>
  </connectionStrings>

  <lightSpeedContexts>
    <add name="default"
          connectionStringName="Dev"
          dataProvider="AmazonSimpleDB" />
  </lightSpeedContexts>

</configuration>

More testing, more problems. I wonder does Mindscape support this tool any longer? After adding a domain with a few properties, I clicked Update Database and received the attached error. Msg -> "LightSpeed does not support updating this type of database". Hopefully I just have a basic configuration issue.

Hi Chris,

Yes the tool is most definitely still supported however the error you are describing is coming from LightSpeed rather than SimpleDB. SimpleDB Management Tools provides a DDEX provider for the Server Explorer which will allow you to drag entities on, however LightSpeed is ultimately responsible for fetching that schema and making any changes. In regards to the error itself this is because we dont have any means within LightSpeed of performing the schema update operations so unfortunately you will need to make those changes manually rather than through the designer.

Thanks for response. Then I find the marketing on your page for SDB Tools incredibly misleading:

SimpleDB Management Tools provides this and makes building LightSpeed domain models and entities over SimpleDB a breeze.

LS seems like a great tool. But, I wasted my time with SDB...
