These aren't errors, per se. They're informational messages saying that debug symbols could/couldn't be found for the each of the assemblies in question.

'iisexpress.exe' (CLR v4.0.30319: /LM/W3SVC/2/ROOT-1-131958557689752173): Loaded 'C:\Windows\Microsoft.Net\assembly\GAC_MSIL\System.Web.DynamicData\v4.0_4.0.0.0__31bf3856ad364e35\System.Web.DynamicData.dll'. Cannot find or open the PDB file.

That's an assembly that forms part of the .NET Framework, for which PDB files aren't supplied, vs:

'iisexpress.exe' (CLR v4.0.30319: /LM/W3SVC/2/ROOT-1-131958557689752173): Loaded 'C:\Windows\Microsoft.NET\Framework\v4.0.30319\Temporary ASP.NET Files\vs\42793b1e\10d72f95\assembly\dl3\09c0d87d\54d37bdf_9bcfd401\BAH.IS_Finance.JE_API.dll'. Symbols loaded.

That's (presumably!) one of the assemblies that forms part of your application. Note that at the end it states Symbols loaded, which indicates that a PDB file has been found and loaded, because Visual Studio generated them and thus they're available.
