The Solution Rating System

With so many solutions, how can you tell which solutions are most likely to help you and which ones are not? To provide you with a tool to use, we rate our solutions based on various elements that most accurately determine if a solution is a quality solution. To explain what factors affect the solution rating, here are the elements we take into consideration when formulating our solution rating.

The Grade of the Solution
The Zone Rank of the Expert Providing the Solution
The Number of Author and Expert Comments
The Number of Experts Contributing
The Feedback of the Community

Your Input Matters
Because of the way the system is set up, the most important variable in this equation is you. As a member of Experts Exchange, you are able to cast your vote on the quality of the solutions in regard to how complete, accurate, helpful and easy to understand each solution is. When you provide your feedback, each rating is adjusted accordingly. So, if you see a solution that has a poor rating that you think is a good solution, let us know by rating it. As you do, the rating will be adjusted and will become more accurate for other members of our site.

If you have any suggestions that you would like to make for our rating system, please ask a question in the Suggestions Zone of Community Support.

Thank you!

'Cannot convert lambda expression to type'... Same code compiles ok in one class, not the other :O

Zones: Language Integrated Query - LINQ, C# Programming Language, .Net Editors & IDEs

Tags: Microsoft, LINQ, Lambda Expression, C#, 3.0, Cannot convert lambda expression to type 'string' because it is not a delegate type

I have an interesting occurence here... I have fairly basic code (using LINQ for entities with the MS entity framework beta from December) which compiles fine in one class. In another class, i repeated the original code and it comes up with an error.

"Cannot convert lambda expression to type 'string' because it is not a delegate type".
It's a very strange as the same code (ive intentionally made it the same now to show how weird this is!

The error points to the 'where' statement within the LINQ query. If i delete the working version, the busted version still fails. If i add another class with the same code, but never in the TargetRepository.

My 'workaround' is to create a new class and hope this doesn't crop up again. Has anyone ever seen this behaviour... is this a known issue? It makes me wonder that it might happen again which would not be helpful!!
