Could not load file or assembly 'Microsoft.SqlServer.BatchParserClien.dll File Name


I have this crazy issue where a SMO operation is failing, and the only difference is this odd file in my bin folder:

Could not load file or assembly 'Microsoft.SqlServer.BatchParserClien.dll

NOTE: That is not a typo, that is the actual name of the file in the file system.

I don't know what to make of this, I have never seen anything like this in my bin folder before.

The operation that I am doing is :

var distributor = new ReplicationServer(conn);
                    if (!distributor.DistributorInstalled)
                        distributor.InstallDistributor((string)null, distributionDb);

I am using the Microsoft.SqlServer.SqlManagementObjects nuget package with version 140.17177.0.

The fusion log in the exception is :

=== Pre-bind state information === LOG: DisplayName = Microsoft.SqlServer.BatchParser, Version=, Culture=neutral, PublicKeyToken=89845dcd8080cc91 (Fully-specified) LOG: Appbase = file:///C:/tfs/Back Office/Persistence/ReplicationManagement/Worker/bin/Debug/ LOG: Initial PrivatePath = NULL Calling assembly : Microsoft.SqlServer.BatchParserClient, Version=, Culture=neutral, PublicKeyToken=89845dcd8080cc91. === LOG: This bind starts in default load context.

ERR: Failed to complete setup of assembly (hr = 0x8007000b). Probing terminated.

The BatchParser file does exist in the bin with the same version specified. I have one project where this works, and the only difference is the file name in the output.

I had a similar issue. I have an SMO application which uses the Microsoft.SqlServer.SqlManagementObjects nuget package.

The app all runs perfectly on my p.c however when it came to deploying it and running it on our app server i was getting the error.

Could not load file or assembly 'Microsoft.SqlServer.BatchParser.dll' or one of its dependencies. The specified module could not be found.

To fix the issue I needed to build the project again targeting x86 platform. I then also had to install the corresponding x86 C++ Redistributable Package

Open PM Console and paste below line
