Hi Rowan,

thx for your response. both assemblies are logical completely the same (i used tools such NDepend, BitDiffer & Framework Design Studio) = both are based on the same source code. if i take a look at a bit comparison (with WinMerge) the assemblies have some different bits (I have no idea why). but I would expect only logical changes lead to problems for ef migrations? i can send you a repro... ricardo.wickel at bewotec de

@Ricardo GER - This suggests that the model in the dll doesn't match the model that was used to generate the last migration (i.e. there have been changes to the model after the last migration was generated). Could this be the case?

We have problems with our build server (tfs) in connection with the ef migrations. with our local builded release dlls, all is ok. but if we build the same code on build server and then run the unit tests, ef migrations have an error with "AutomaticMigrationsDisabledException: Unable to update database to match the current model because there are pending changes and automatic migration is disabled". have you any idea?

@Mike Nacey - There are APIs you can use but that's not going to be a great option for you. I'm running the same setup - Windows 7 X64 VS 2010 SP1 without issue... of course there are a lot of other variables at play too :) Do you have the latest version of NuGet? I'm wondering if upgrading might get rid of the issue for you. If you have the latest version of NuGet and VS is consistently crashing for multiple solutions, then use the 'Email Blog Author' link at the top right of the page to make contact with us and we'll try and work out what is happening.

My package manager console just crashed VS 2010 whenever I try to use it, so this is not helpful. Is there some other way to enable migrations?

@IsmailS - Brice is on the EF team too, you probably noticed that he opened a couple of bugs against the MySQL provider to get the issues fixed.

@Rowan thanks for considering the issue.

I found today on stackoverflow.com/.../148271 that some digging on this issue has already been done here brice-lambson.blogspot.in/.../using-entity-framework-code-first-with.html.

Just thought it will be useful to you.
