Do as it says! It's a warning/information shared. Do right click, properties of that assemble and unlock it for use. (There will be an option near 'Readonly' at the bottom that will clearly state on how to unlock it.)

Welcome.

@Sandeep it's not recommended the use of untrusted dll. If he downloaded from another site. Dll located on the Blend folder is garanteed. What do you think?

Sandeep Mewara 30-Aug-12 8:36am

If it downloaded from trusted source, then it is fine.

Christian Amado 30-Aug-12 8:39am

Totally true too :)

Christian Amado 30-Aug-12 8:39am

5'ed :)

Christian Amado 30-Aug-12 8:39am

You can download trial. Why you want that library if you haven't got Blend?

Solution 2

Try to load the library from:
c:\ProgramFiles(x86)\Microsoft SDKs\Expression\Blend\Silverlight\v4.0\Libraries\Microsoft.Expression.Controls.dll

"Of course, you must have Microsoft Expression Blend installed on your development computer."

v4.0 can be replaced with your silverlight version used in your project.

Set Local Copy to True in dll reference's property.

Hope it helps
