Danko, 

I discovered the problem. It seems that adding the Ingragistics Theme files is the reason for slowness.

thanks

Danko,

I am having exactly the same problem. I am working on a Silverlight 4 project with Infragistics Controls. VS 2010 has got incredibly slow during the last 10 days. It seems to be fine working with projects where I am not using Infragistics SL controls.

many thanks 

Hello JohnWidhalm,

I have created the following case for you, where we could continue with our conversation about this issue : CAS-74026-P5HKFF

Please feel free to let me know here or through the case if you have any other questions.

Thank you for the reply.  I followed your instructions and cannot find a specific version under the "Service Releases" section - it only says "Service Release".  The only section I see version information is under the "Source Code" section. I have no way of know which service release I am using.  I installed the version I am using in late August (August 22 I believe) so that may help.

Hello johnWildhalm

Thank you for the provided information.

I would like to ask you what service release for NetAdvntage 2011 vol1 you are using in your test application?

If this is not the latest one could you please log to your account in our web site and under "My IG"  select ‘Keys & Downloads’. Select the appropriate tab for this product, then the license key. The available service releases should now be listed on the page.

If you are able to perform your tests one more time against the latest service release could you please let us know what are the results after that.

Thank you for your assistance.
