signing assembly strong name / signtool

A) STRONG NAME

1) you need SDK Tool SN:
C:\Program Files (x86)\Microsoft SDKs\Windows\v10.0A\bin\NETFX 4.6.1 Tools\x64\sn.exe

2) create key file:
sn -k StrongNameKeyFile.snk

3) sign the assembly in Visual Studio
in VisualStudio open Project Properties,
Signing,
Sign the assembly and choose the StrongNameKeyFile.snk from (2)

4) check if assembly is strong named:
sn -v assembly name
=> output ....exe stellt keine Assembly mit einem starken Namen dar.
oder
=> output Die Assembly "....exe" ist gültig

B) SIGNTOOL

C:\Program Files (x86)\Windows Kits\10\bin\x64

/a automatically selects the code signing certificate with the longest valid date:

signtool sign /a yourApp.exe 

=> output Done Adding Additional Store 

Succeddfully signed: yourapp.exe

=> there is a new Tab in Windows File Properties named "Digital Certificates" which shows the cert owner

buildtarget and BadImageFormatException

http://stackoverflow.com/questions/5229768/c-sharp-compiling-for-32-64-bit-or-for-any-cpu

On a 32-bit machine:

• Any CPU: runs as a 32-bit process, can load Any CPU and x86 assemblies, will get BadImageFormatException if it tries to load an x64 assembly.
• x86: same as Any CPU.
• x64: BadImageFormatException always.

On a 64-bit machine:

• Any CPU: runs as a 64-bit process, can load Any CPU and x64 assemblies, will get BadImageFormatException if it tries to load an x86 assembly.
• x86: runs as a 32-bit process, can load Any CPU and x86 assemblies, will get BadImageFormatException if it tries to load an x64 assembly.
• x64: same as Any CPU.

It is the JIT compiler that generates an assembly code that's compatible with the requested target based on this flag.

UEFI New Boot drive

https://forum.acronis.com/forum/25975

On a Dell Latitude I had to go into the BIOS settings under boot sequence. Then under the UEFI settings it will show the Windows Boot for the old hard drive. It seems to be tied to the serial of the drive. If you click on add new, it will populate with the cloned drive serial, you simply just give it a name (I called it Windows New) and copy the boot location from the existing entry (bottom line). The EFI files it needs to boot with are stored in a hidden partition on the drive (which also much be cloned) - this is what you are pointing to.

certificates / Zertifikate basics

drei Punkte Menü ganz rechts, unteres Drittel weitere Tools, Entwickler => Security Tab (fentesr etwas breiter machen damit Security Tab sichtbar wird)

Klassen

Class 1 for individuals, intended for email.

Class 2 for organizations, for which proof of identity is required.

Class 3 for servers and software signing, for which independent verification and checking of identity and authority is done by the issuing certificate authority.

Class 4 for online business transactions between companies.

Class 5 for private organizations or governmental security.

Formate:

from http://serverfault.com/questions/9708/what-is-a-pem-file-and-how-does-it-differ-from-other-openssl-generated-key-file

• .csr This is a Certificate Signing Request. Some applications can generate these for submission to certificate-authorities. The actual format is PKCS10 which is defined in RFC 2986. It includes some/all of the key details of the requested certificate such as subject, organization, state, whatnot, as well as the public key of the certificate to get signed. These get signed by the CA and a certificate is returned. The returned certificate is the public certificate (which includes the public key but not the private key), which itself can be in a couple of formats.
• .pem Defined in RFC's 1421 through 1424, this is a container format that may include just the public certificate (such as with Apache installs, and CA certificate files /etc/ssl/certs), or may include an entire certificate chain including public key, private key, and root certificates. Confusingly, it may also encode a CSR (e.g. as used here) as the PKCS10 format can be translated into PEM. The name is from Privacy Enhanced Mail (PEM), a failed method for secure email but the container format it used lives on, and is a base64 translation of the x509 ASN.1 keys.
• .key This is a PEM formatted file containing just the private-key of a specific certificate and is merely a conventional name and not a standardized one. In Apache installs, this frequently resides in /etc/ssl/private. The rights on these files are very important, and some programs will refuse to load these certificates if they are set wrong.
• .pkcs12 .pfx .p12 Originally defined by RSA in the Public-Key Cryptography Standards, the "12" variant was enhanced by Microsoft. This is a passworded container format that contains both public and private certificate pairs. Unlike .pem files, this container is fully encrypted. Openssl can turn this into a .pem file with both public and private keys: openssl pkcs12 -in file-to-convert.p12 -out converted-file.pem -nodes

A few other formats that show up from time to time:

• .der A way to encode ASN.1 syntax in binary, a .pem file is just a Base64 encoded .der file. OpenSSL can convert these to .pem (openssl x509 -inform der -in to-convert.der -out converted.pem). Windows sees these as Certificate files. By default, Windows will export certificates as .DER formatted files with a different extension. Like...
• .cert .cer .crt A .pem (or rarely .der) formatted file with a different extension, one that is recognized by Windows Explorer as a certificate, which .pem is not.
• .p7b Defined in RFC 2315, this is a format used by windows for certificate interchange. Java understands these natively. Unlike .pem style certificates, this format has a defined way to include certification-path certificates.
• .crl A certificate revocation list. Certificate Authorities produce these as a way to de-authorize certificates before expiration. You can sometimes download them from CA websites.

---

In summary, there are four different ways to present certificates and their components:

• PEM Governed by RFCs, it's used preferentially by open-source software. It can have a variety of extensions (.pem, .key, .cer, .cert, more)
• PKCS7 An open standard used by Java and supported by Windows. Does not contain private key material.
• PKCS12 A private standard that provides enhanced security versus the plain-text PEM format. This can contain private key material. It's used preferentially by Windows systems, and can be freely converted to PEM format through use of openssl.
• DER The parent format of PEM. It's useful to think of it as a binary version of the base64-encoded PEM file. Not routinely used by much outside of Windows.

            var sbNewClient = new Service1.ServiceClient(cb,endPoint);

WCF BASICS 2

1) ServiceContract & Implementation

you need a contract  (=Interface with     [ServiceContract] Attribute) like

    [ServiceContract]
    public interface IService1
    {
        [OperationContract]
        string GetData(int value);

which contains Methods attributed with [OperationContract]

implement the [ServiceContract] Interface:

    public class Service1 : IService1
    {
        public string GetData(int value)
        {
            return string.Format("You entered: {0}", value);
        }

assume its in namespace WcfServiceLib for hosting below

2) Host the ServiceContract

2a) with IIS

you need a .svc file with one single line:

<%@ServiceHost Service="WcfServiceLib.Service1"%>

and configure the service (provide metadata) within the web.config:

    <system.serviceModel>

      <behaviors>

        <serviceBehaviors>

          <behavior name="MyServiceTypeBehaviors">

            <serviceMetadata httpGetEnabled="true" />

            <serviceDebug includeExceptionDetailInFaults="false" />

          </behavior>

        </serviceBehaviors>

      </behaviors>

        <service name="WcfServiceLib.Service1"      behaviorConfiguration="MyServiceTypeBehaviors">

          <endpoint address="" binding="wsHttpBinding"

               contract="WcfServiceLib.IService1"/>

          <endpoint contract="IMetadataExchange"

             binding="mexHttpBinding" address="mex"/>

        </service>

      </services>

    </system.serviceModel>

2b) With .net app:

        static void Main(string[] args)

        {

            Type serviceType = typeof(MyWCFServices.HelloWorldService);

            string httpBaseAddress = ConfigurationManager.AppSettings["HTTPBaseAddress"];

            Uri[] baseAddress = new Uri[] { new Uri(httpBaseAddress) };

            ServiceHost host = new ServiceHost(serviceType, baseAddress);

            host.Open();

            Console.WriteLine("HelloWorldService is now running. at: " +host.BaseAddresses.First());

            Console.WriteLine("Press any key to stop it ...");

            Console.ReadKey();

            host.Close();

        }

Sql Server Filetable (since 2012)

1.) Filestream TSQL

A) Pepare SQL Server

1) configuration Manager / SQL-Server Db Service Propteries / Filestream Tab: Check all
2) EXEC sp_configure filestream_access_level, 2  RECONFIGURE
3) restart SQL Server Service

B) Prepare DATABASE

ALTER DATABASE testFileTable SET FILESTREAM (NON_TRANSACTED_ACCESS = FULL, DIRECTORY_NAME = N'FilesDir')

alter database testFileTable  ADD FILEGROUP fsg CONTAINS FILESTREAM;
ALTER DATABASE testFileTable  ADD FILE ( NAME = N'fsf', FILENAME = N'D:\sqlData\filesteamtest\' ) TO FILEGROUP fsg;
ALTER DATABASE testFileTable  SET READ_COMMITTED_SNAPSHOT OFF WITH NO_WAIT;

C) Prepare TABLE

CREATE TABLE dbo.MyFiles AS FILETABLE
WITH
(
FILETABLE_DIRECTORY = 'MyFilesDir',
FILETABLE_COLLATE_FILENAME = database_default
)

D) Write Files

just drag them into the filetabledir - get UNC Path of it:

SELECT FileTableRootPath('TestFileTable') AS FileTableRootPath

or
INSERT INTO [dbo].[FileTableTb] ([name],[file_stream])SELECT'NewFile.txt', * FROM OPENROWSET(BULK N'd:\NewFile.txt', SINGLE_BLOB) AS FileData
or
INSERT INTO [dbo].StpFile ([name],[file_stream]) SELECT 'test1.txt', CONVERT(VARBINARY(MAX),'TestFileText') AS FileData

create Dir:
INSERT INTO FileTableTb (name, is_directory)   VALUES ('testFolder', 1)

GO

create file in subdir: have to get pathlocator first:

select GetPathLocator(CONCAT(FileTableRootPath('FileTableTb'), '\testFolder')).GetDescendant(Null,NULL);

INSERT INTO [dbo].FileTableTb  ([name],[file_stream],path_locator) SELECT 'test1.txt', CONVERT(VARBINARY(MAX),'TestFileText'), GetPathLocator(CONCAT(FileTableRootPath('FileTableTb'), '\testFolder')).GetDescendant(Null,NULL) AS FileData

Parent_Path_Locator column is readonly !

E) Read Files

with Explorer - get UNC Path of filetable:
SELECT FileTableRootPath('TestFileTable') AS FileTableRootPath

physical path of filetable isn't available, this UNC Path is given by a virtual device
The Filetable stores the files like filestream in a guid structure but offers a filesystemdriver, which respresents those files in a more readable form under a UNC Path, which is available from:
SELECT FileTableRootPath('TestFileTable') AS FileTableRootPath

select stream_id, name, convert(varchar(max), file_stream) as textContent, file_stream.GetFileNamespacePath() as RelPath,
FileTableRootPath('TestFileTable')+file_stream.GetFileNamespacePath() as AbsPath from TestFileTable

Sql Server Filestream using C#

1) WRITE

            using (TransactionScope transactionScope = new TransactionScope())
            {
             
                //1. create Record with Empty Blob (File)
                SqlConnection sqlConnection1 = new SqlConnection(conStr);
                sqlConnection1.Open();

                SqlCommand sqlCommand1 = sqlConnection1.CreateCommand();
                sqlCommand1.CommandText = @"DECLARE @Out TABLE (ID uniqueidentifier)
                                            Insert Into Blob2(Blob) output inserted.ID into @Out values(Cast('' As varbinary(Max)))
                                            Select BLOB.PathName() As Path From BLOB2 Where Id =(SELECT id FROM  @Out)";
                string filePath1 = (string) sqlCommand1.ExecuteScalar();

                //2. Get SqlFileStream to empty File createt in Step 1
                SqlConnection sqlConnection2 = new SqlConnection(conStr);
                sqlConnection2.Open();

                SqlCommand sqlCommand2 = sqlConnection2.CreateCommand();
                sqlCommand2.CommandText = "Select GET_FILESTREAM_TRANSACTION_CONTEXT() As TransactionContext ";
                byte[] transactionContext1 = (byte[]) sqlCommand2.ExecuteScalar();

                //3. Write Data into Stream and Close
                SqlFileStream sqlFileStream1 = new SqlFileStream(filePath1, transactionContext1, FileAccess.Write);
                byte[] fileData = Encoding.ASCII.GetBytes(nameof(AdoFileStreamTest)+" "+DateTime.Now);
                sqlFileStream1.Write(fileData, 0, fileData.Length);
                sqlFileStream1.Close();
                transactionScope.Complete();
            }

2) READ

            using (TransactionScope transactionScope2 = new TransactionScope())

            {

                SqlConnection sqlConnection3 = new SqlConnection(conStr);

                sqlConnection3.Open();

                //1. Get Path & Transaction Scope

                SqlCommand sqlCommand3 = sqlConnection3.CreateCommand();

                sqlCommand3.CommandText = @"Select Top 1 Blob.PathName() As Path,

                                            GET_FILESTREAM_TRANSACTION_CONTEXT() As TransactionContext

                                            From Blob2 Order by Created desc";

                

                SqlDataReader reader = sqlCommand3.ExecuteReader();

                reader.Read();

                string filePath = (string)reader["Path"];

                byte[] transactionContext2 = (byte[])reader["TransactionContext"];

                //2. read file

                SqlFileStream sqlFileStream2 = new SqlFileStream(filePath, transactionContext2, FileAccess.Read);

                byte[] data = new byte[sqlFileStream2.Length];

                sqlFileStream2.Read(data, 0, Convert.ToInt16(sqlFileStream2.Length));

                res = Encoding.ASCII.GetString(data);

                sqlFileStream2.Close();

            }

3) maybe need to config Distributet Transaction Manager:

In the console tree, click to expand Component Services, click to expand Computers, click to expand My Computer, and click to expand Distributed Transaction Coordinator. Right click Local DTC, and click Properties to display the Local DTC Properties dialog box. Switch to the Security tab. In the Security Settings section, click Network DTC Access. In the Client and Administration section, select Allow Remote Clients and Allow Remote Administration. In the Transaction Manager Communication section, select Allow Inbound and Allow Outbound. In the Transaction Manager Communication section, select Mutual Authentication Required (if all remote machines are running Windows Server 2003 SP1 or Windows XP SP2 or higher), select Incoming Caller Authentication Required (if running MSDTC in a cluster), or select No Authentication Required if some of the remote machines are pre-Windows Server 2003 SP1 or pre-Windows XP SP2. No Authentication Required is the recommended selection. Select Enable XA Transactions, and then click OK.

Entity Framework no InsertFunction element exists

because it has a DefiningQuery and no InsertFunction element exists in the ModificationFunctionMapping element

most likly: No primary key defined => EF treats Table as view and generates read only code

I had to remove the DefiningQuery Element in the .edmx File and also I removed the store: 

like described here:
